How to check what your computer is capable of. What could be causing your computer to slow down? Cleaning your hard drive

Hi all! Many PC owners often catch themselves thinking that their machine is not working fast enough, or “freezes,” so to speak.

In this case, it is worth testing your “iron friend” and identifying the reason for this behavior. Today I will tell you how to check the speed of your computer. But first, let's decide why we need to do this.

Why is verification needed?

You should spend valuable time on tests for a number of reasons:

• Testing will allow you to understand which tasks your computer can perform easily and which are difficult for it.
• If you are going to purchase a new PC or laptop, then using the results of the check, you can choose the most suitable model that will meet all your needs.
• You'll know which components are slow and can replace them during the upgrade.
• You can compare the characteristics of your computer with the PC of one of your friends and find out whose PC is the most powerful.

How to do it?

Well, checking speed is a very necessary and important thing, but how can you find out the speed, how can it be measured? In order to find out the speed of your computer, you will need a PC with Windows installed on it, the usual set of applications for this OS, and my instructions, which I will describe below.

You can check with with the help of three simple ways:

1. using the Windows Performance Level Index;
2. using the windows task manager, which should already be familiar to you;
3. usage-based special programs.

Let's look at each of them in detail.

First way

In Windows OS there is one extremely useful utility program called "Performance Index". This application takes measurements of your PC's performance, shows you a score for each, and, of course, evaluates overall system performance. In this case, the size of the overall indicator does not exceed the smallest indicator among the elements.

In versions 7, 8 of Windows and Vista, in the Control Panel you need the “Performance Counters and Tools” section (in Windows xp you cannot check performance in this way).

If we talk about the 7th version: the maximum score is 7.9, the average is from 3.5 to 5. If the performance level index is more than five, then you don’t have to worry about anything. However, if the scores are below the “3.5” rating, then your PC should either be replaced with a new one or upgraded to the old one (which will be much cheaper).

In Vista the maximum is 5.9, and in 8 it is 9.9.

In windows 8.1 and 10, performance testing is carried out using shell PowerShell. To open it in the search bar on start screen write “PowerShell”, in the search results, right-click on the icon of the found utility and select context menu"Run as administrator" line.

IN windows program PowerShell type winsat formal and press Enter. As a result of these actions you will see the following:

There is one small feature: if you are doing the test on a laptop, it must be connected to a 220V network, otherwise the program will generate an error.

The whole process may take a few minutes, and the result will be saved here: C:\windows\Performance\WinSAT\DataStore\...Formal.Assessment (Recent).WinSAT.xml.

In a programme windows PowerShell You cannot test the system without administrator rights; you can only view the performance ratings given as a result of the previous test. To do this, write “Get-CimInstance Win32_WinSAT” and press Enter. As a result you will see:

Second way

If you want to have an extremely accurate idea of ​​what the speed of your system is, then this method will be most convenient for you. Its main advantage over the above is that it is able to demonstrate not only how fast the computer itself is, but also how fast its individual elements are.

To determine the quality of work using this method, it is necessary to perform the following actions:

1. Press the Alt, Ctrl, Delete keys simultaneously.
2. Click on “Task Manager”.
3. In the task manager, select the tab called “Performance”.

In “Performance” you will see how well your computer is functioning. If the level of quality of its work is insufficient, then you can try to upgrade your machine.

The graphs allow you to determine whether your PC is running slowly due to CPU load or lack of random access memory. The green line indicates great job, yellow - about the acceptable level, but if the line is red, then it is urgently necessary to take action.

Third way

This method involves using special programs. There are special applications that are created specifically to collect data about the state of the computer.

There's just a ton of all kinds of tests, numbers and information. With these products you can get the most comprehensive data about the performance of your PC. What kind of programs are these? Here is a list of those that I have used at least once:

Everest. Created primarily for analysis of PC configuration, but provides a large number of various tests.

SiSoftware Sandra. At the moment, the best option if you want to test the level of performance.

3Dmark. His main specialization is testing computer video cards. Consists of a huge amount different tests texturing, working with 3D modeling, etc. There is also a comprehensive testing option, reminiscent of a video game that is played not by you, but by the program. During its work, it evaluates the stability of the video card during heavy loads and measures the frame rate.

PCMark. This is lightweight software designed for limited use. Serves only to check performance. Allows you to perform integral testing of any PC component. main feature is the ability to compare the performance of your own computer with the world average.

You can download these programs from the official Internet resources of their developers online.

Well, that’s all, dear friends! In the end, I would like to tell you about a training course, the effectiveness of which I was able to “test” on myself. We are talking about the course “Secrets of successful computer work.”

What distinguishes this course from a huge number of other similar courses is primarily the author’s high professionalism and simplicity of presentation. All the intricacies of working on a PC are presented so simply and clearly that even elderly people, who are known to shy away from modern technology, within a couple of months of training they turn into experienced users.

I wish you to be computer literate people, and I and my blog will help you become so. Therefore, do not forget to subscribe to updates and follow the release of a new article.

How to check computer performance: 3 working options

Hello! Sometimes you want to rejoice at the high power of your personal computer (PC), and sometimes you want to find out what is causing the drop in performance. I hope you have a reason to rejoice. If not, then the problems can be eliminated. There's nothing wrong.

Today we’ll look at how to check your computer’s performance in three ways. The first two of them are quite simple, but the last one is more suitable for conducting professional tests of the equipment and software of the device.

My previous publication will be a useful addition to the current material. It describes what PC performance depends on.

Let's start looking at specific options.

A way to check the power and performance of a computer

Let's look at the data that the operating systems (OS) Windows XP and 7 can output. In both, I will do the following:

• I’ll find the “my computer” icon and right-click on it;
• In the context menu that opens, I’ll select “properties” and take a look at the results.

Now I'll show you what happened. First for XP, then for Windows 7.

Data about the power of the computer and its maximum performance is enough only for a superficial assessment. Despite this, the information is quite useful. Find out more information additional ways, which we will talk about later in the text.

If you use seven, then in the above window you can click on the phrase “performance index”. Extended information about the PC's capabilities will be displayed.

As you can see, more detailed evaluations of the work are presented here various components systems.

Real-time performance test

For this we need a task manager. We call it via the Ctrl, Alt, Del buttons on the keyboard. After it appears, open the “performance” tab.

This provides summary information about memory and central processing unit (CPU) load in real time. My CPU load is divided into two graphs. Their number corresponds to the number of cores in the processor.

Based on the data displayed on the screen, we can draw a couple of conclusions about the performance of the computer:

• All or almost all resources are used. This means that one or more programs or processes are creating an overload. It may be due to weak computing power, software or hardware failure. It happens that everything has an effect at once.
• There are no overloads, there is a supply of resources and everything is working fine. In this case, everything is in order, you can only rejoice.

It happens that the data obtained as a result of the above-described checks is not enough. In this case, you can use special programs that can display the mass detailed information. We will now briefly consider one of them.

Professional computer speed tests

They can be carried out using the AIDA64 program. Have you ever heard of her? It has trial and paid versions. This is not surprising, because it allows you to really get mass useful information. In particular, its functionality allows you to display detailed information about the configuration of the software and hardware of the PC.

Individual functions allow you to evaluate the speed of your computer when performing various operations. After testing is completed, it is also possible to compare the capabilities of the current configuration with its possible modifications.

In general, the usefulness of the program is very high. If you wish, you can study it in more detail.

What are these checks for?

If you saw in previous publications, then you know that I professionally do PC maintenance and computer networks. I periodically have to check the performance and configuration of computers. In short, the test results are useful for the following types of work:

• troubleshooting errors in programs, including various operating systems;
• identifying microcircuits that have ceased to function normally;
• selection of programs based on the technical capabilities of the equipment;
• selection of compatible components (chips) for PC modification.

Of course, we are pleased with situations when, after checking the performance, it turns out that everything is working properly and technical intervention is not yet required.

I will conclude today’s topic with this. Was the information useful? I hope they will help you understand how to check the performance of your computer in detail and help you carry out some work on competent maintenance computer technology.

PC maintenance, working with programs and global network- these are related topics to the main ones. These include work and part-time work on the Internet, professional website promotion. The efficiency of earnings can be significantly affected by the condition of working equipment. Therefore, I delve into some of the intricacies of working with it.

By the way, do you know which areas of earning money online are really promising and can bring good money? I have already talked about some ways to earn money in previous publications. Have you read it?

The blog is updated periodically. You can receive information by email. There is a free subscription. I also created pages and groups on social networks. Publication announcements can be viewed there. See you later.

How to check the speed of your computer and why is it necessary?

Why do tests to check your computer's speed?

1. The tasks that the computer can perform are determined.
2. Individual components of the computer assembly are checked for subsequent replacement.
3. The characteristics of a newly purchased computer are checked to select a model suitable for specific needs.

Options for measuring the performance of a laptop or PC:

• Determine the Windows performance level index.

In the seventh and eighth versions of Windows installed standard program, giving a performance rating (index). Behind average The lowest rating of one of the components (processor, RAM, graphics and hard drive) is taken.

The function is not available in versions XP and 10; the performance index can be calculated using command line or PowerShell (the screenshot shows the command that calculates the score and execution result).

• Check performance through the task manager.

Press CTRL+ALT+Delete, selecting "Task Manager" in the dialog box. Open the Performance tab.

The performance of computer hardware system components is presented in the form of graphs.

• Use appropriate programs.

Download one of the programs that collect data about the state of your computer from developer web pages (Everest, 3DMark, PCMark, etc.).

How to increase computer speed

1. Replacement of components (RAM, hard drive, video card or processor).

The “weak link” in the assembly is determined using a performance index. It is preferable to replace the processor - the performance of other components depends on the speed of data processing by the processor.

1. Cleaning your hard drive, checking for viruses.

Additionally, clean the computer system unit or laptop cooling system. Due to overheating of the motherboard, performance is noticeably reduced.

Defragmentation allows you to collect parts of information stored on a disk into one whole. This reduces the time it takes to access a document or file, and improves overall productivity.

The partition of the disk where operating system files are stored must contain at least 1 GB of free space, and the entire HDD– at least 30% of the total volume.

It is not necessary to act on the principle of “seven troubles - one reset”. But if you often download new programs to your computer or delete old ones, parts of the uninstalled programs will remain in folders on the disk, in registry entries, etc. If you are not sure that you will clean the registry or system storage correctly, reinstall Windows once a year.

1. Changing BIOS settings.

BIOS is a routine that automatically starts when the device is turned on. It contains minimal PC settings.

Go to the BIOS menu (when starting the OS, press F2, F10 or Delete, depending on the laptop model) and set the optimal parameters by checking the “Load Optimal Settings” item.

Increasing the speed of the user's PC

If there are a lot of programs on the computer (games, text editors, utilities, etc.), then it will slow down. How to release resources?

1. Quit unused applications. At the bottom right of the monitor are icons for running programs, some of which run in the background. Right click on the program icon → Exit.

Or use the Task Manager (CTRL+ALT+Delete) to kill unnecessary processes.

1. Optimize startup mode. Press the Win key combination (with the Windows logo) and R at the same time and type msconfig in the dialog box. On the Startup tab, check programs and disable utilities that you do not need every time you start the device (programs for printers, screenshots, CCleaner, etc.).
2. Modify your desktop style. Go to Control Panel → System and Security → Other system settings. Click on “Advanced” and “Performance”. In the settings, select “Visual Effects” and check the “Ensure the best performance” checkbox.

Computer speed and web page loading speed

The loading speed of websites on a PC or laptop is checked online (special programs and utilities will not be downloaded to your computer). Follow the links to start testing:

• http://2ip.ru/speed/
• http://ru/
• http://internet.yandex.ru/

Speed ​​values ​​based on testing results are measured in Kbit/s or Mbit/s. Divide the values ​​by 8 to get regular kilobytes and megabytes per second.

For example, on the provider’s website in the tariff description the speed is 80 Mbit/s. By connecting to the tariff, you will receive web pages loading at a speed of 10 megabytes per second.

Software that evaluates the loading speed of web pages

1. Google PageSpeed Insights

Created by the company's developers Google tool gives a speed rating from 0 to 100. Convenient in that it gives both the test result and recommendations for speeding up loading, indicating “ weak spots» site.

Calculates the average time required to load a page and the number of hits to the server for a specific period. Each request to the server is decomposed into received scripts, images and other page elements, and then using this data, components that slow down loading are determined.

The program is useful for web developers to evaluate the performance of their website and a competitor’s website. Shows a comparison of two sites and highlights the page that loaded faster.

It differs from similar utilities in that it contains a history that allows you to track the development of the site and check whether loading has accelerated or slowed down. When problems are found, it issues recommendations from Yahoo and Google, first downloading those that are priority for the user.

How to find out how many cores there are on a computer?

To determine how many cores a computer has, you do not need to install new software on the device. Let's use the built-in windows tools.

Start menu → right click on “Computer” → Device Manager.

In the window that appears, expand the “Processors” branch. The number of elements in the drop-down list is the number of cores on the laptop/computer.

The second way to determine the number of cores:

• Click right key mice on empty space panels quick access.
• From the list, select “Starts Task Manager.”
• Open the Performance tab.
• At the top of the window there are several windows for the CPU load chronology. The number of windows is equal to the number of processor cores. The graphs in the windows show how busy central memory over the past period of time.

For versions 7, 8 and 10 of Windows, laptops with quad-core processors are released. Therefore, if your device has fewer than four cores, install the appropriate OS version to increase performance.

How to improve computer performance

It would seem that a quite fast computer, which at first completely satisfied with its capabilities, begins to slow down over time. What could cause this decrease in performance? Or there is another situation when you need to work in very resource-intensive programs (games), but the computer simply cannot handle them. In any case, the user is faced with a PC performance problem that needs to be solved.

In this article we will look at the main reasons that lead to a decrease in power and tell you how to increase computer performance.

The main signs of a slow computer are:

The points:

1. Long switch on and the same long shutdown of the computer.
2. Many programs take a very long time to launch, loading games takes a very long time.
3. The cursor response may not keep up with mouse movements, may slow down, or there may be a late response to a click.
4. And other signs of slow PC operation, which makes the user nervous.

What could be causing your computer to slow down?

If the computer slows down, then the reason (or several reasons at once) may be the following:

1. Poor compatibility of software, operating system, games with the hardware configuration of the computer itself.
2. Large fragmentation of the file system, a lot of software junk has accumulated on the hard drive.
3. Problems with the operating system, crashes, incorrect setting.
4. A large number of running services that are not needed.
5. Infecting your computer with malware.
6. Software conflicts (between drivers, antiviruses, etc.).
7. Poor thermoregulation, cooler failure, clogged radiators.
8. Violation of basic parameters in the BIOS.

How to solve this problem and improve computer performance?

There are many ways to speed up your computer. We offer ten methods for improving PC performance that have shown their effectiveness in practice.

1. Let's upgrade the hardware.
2. Cleaning the insides, repairing faulty elements of the cooling system.
3. We clean the hard drive of everything unnecessary and perform defragmentation.
4. Reinstalling the operating system.
5. We optimize the operation of the OS.
6. Setting up the BIOS.
7. Disable everything unnecessary, control autoloading.
8. We are updating drivers.
9. We install the operating system corresponding to our PC.
10. We clean the system from viruses.

Determining performance

Windows 7 is already built into the operating system special function to check system performance and computer speed.

Open the Start menu and in the special search field (located at the bottom of the menu) enter “proiz”, as shown in the figure.

Among the search results will be the program “Improving computer performance.” Launch it and the following window will open.

Click on the “Repeat assessment” button below. The program will begin to analyze the productivity of your system and upon completion will provide results from which you can draw a conclusion about the speed of your computer.

After this, you can begin to improve your computer's performance using the chosen methods.

We upgrade computer components

Many who are the “lucky” owner of a slow computer have a strong desire to replace it with something more powerful. But we will not move in this direction; it is only suitable for seriously outdated computers. In most cases, replacing just one or a few weak parts is enough to get the whole system flying again - this method will be much cheaper than buying a new PC.

• CPU. The point of replacing the “stone” will be truly justified only if the new one greatly exceeds the old one in power, by at least 30%. Otherwise, you won't feel a big difference, but you will spend a lot of money.

Risk-takers can try to overclock the central processor. This method is not suitable for many, because not every CPU can be overclocked. But if successful, the purchase of a new “stone” can be postponed for another year. Read our recommendations for choosing a processor. The essence of this operation is to increase the voltage on the central processor, and thereby increase its clock frequency. The operation itself is quite risky and not for all processors; in some cases, you can simply disable the CPU, or significantly reduce its service life.

To roughly determine the weak points of the system, use the built-in function for assessing computer performance, which we have already discussed above. The “weak link” can be determined by the assessments that are obtained after checking the performance. Where the score is lowest, in that direction it is necessary to increase the PC power. For example, if the disk data transfer speed has the lowest rating, then you should think about buying a faster hard drive.

Cleaning the insides, repairing faulty elements of the cooling system

Various faults in the cooling system can also significantly slow down the operation of the entire system. If the cooler on the central processor breaks down, this leads to its overheating and a decrease in clock frequency.

Overheating is generally a dangerous thing and can occur even with a working cooling system. Take it, remove the cover from your system unit, and see how much dust there is. It not only covers all surfaces, but also gets tightly packed into all radiators and settles on the cooler blades. Dust acts as a kind of heat insulator, which leads to overheating. Clean the system unit very carefully and you will be able to increase the speed of your computer, as well as extend the life of its components and get rid of the main breeding ground for various allergens and bacteria - dust.

We clean the hard drive of everything unnecessary, perform defragmentation

Those who hear the term “defragmentation” for the first time should understand that this is the very first thing to do to improve system performance. Defragmentation allows you to collect various fragments of programs that are in different parts hard drive, in one pile. Thanks to this, the hard drive reader does not need to perform many unnecessary movements across the disks, because everything is in one place. This way productivity increases.

In addition, you need to get rid of unnecessary information and any software junk that accumulates on the disk over time. This is especially important when there is practically no free space on the operating system partition. If the space is less than 2 GB, the system loses its performance. So don’t overload the disk and try to have thirty percent free space on it, if possible, of course.

Reinstalling the operating system

This step almost always helps speed up your computer. In some cases, productivity can triple. This is simply the essence of the operating system; over time, various errors accumulate in it, it becomes clogged unnecessary services, which even perform major changes to the system itself. This and much more leads to a deterioration in the speed of the computer; many operations now require much more time.

If you carefully monitor the cleanliness of the system and do not install anything there, you can use the same Windows for years. But most often, there is constant movement on the computer: programs are installed and uninstalled, drivers are updated, large volumes are downloaded various information- in such conditions the system gradually begins to “stupid”. It is best, for prevention, to format the disk about once a year and install a new operating system from scratch.

We optimize the operation of the OS

We recently made a selection of the best programs for optimizing a computer, because a properly configured and optimized system is the main guarantee of computer performance! The system can be configured quickly and without unnecessary hassles using special utilities. For example, AeroTweak copes well with these tasks.

The PCMedic program performed well. The main feature of this utility is the complete automation of all operations. You just need to select the appropriate parameters and start the setup process.

The program consists of only one main window. Here we select our operating system, the type of central processor (for example, Intel or AMD), then we need to choose one of two optimization methods - Heal (cleaning the system), or Heal & Boost (in addition to cleaning, acceleration is also performed). After selecting all the parameters, click on the “Go” button - the program will do everything necessary changes.

There is another program that boasts truly powerful functionality - Ausloqics BoostSpeed, which, unfortunately, is paid. It consists of several utilities that allow you to optimize the system in almost all directions. Using this application you can defragment, clean the file system, clean the registry, increase Internet speed and much more. The program has a built-in advisor that helps determine priority areas in system optimization. Although I recommend not to blindly trust an adviser and see whether all these actions are really necessary for you.

In order to clean the system of all junk, there are many special applications for the cleaning. For example, CCleaner can be a good help. It is capable of cleaning the disk from unnecessary, temporary files and cleaning the registry. By deleting unnecessary files, you can increase the amount of free space on your hard drive. But when cleaning the registry, there is no significant increase in performance. But if some important parameter is accidentally deleted, the system will begin to generate errors and this can lead to serious failures.

ATTENTION! Before performing all these steps, it is highly recommended that you create a restore point!

ALWAYS look at the files that system cleanup utilities remove. There are cases permanent deletion necessary and even important files that programs falsely mistook as unnecessary, or temporary files.

Windows 7 users can slightly improve the speed of their computer by simplifying the graphical interface. To do this, open the Control Panel and go to the “System” section, open the “Advanced” item and select “Settings”. Here we remove some of the unnecessary checkboxes, or set the switch to the position to ensure best performance.

Setting up the BIOS

The BIOS stores computer parameters that are responsible for hardware, OS loading, time and other key elements. To get into BIOS settings, while turning on the PC, before loading the operating system itself, press the Del, F2 or other key (this depends on the motherboard manufacturer, usually the name of the key is displayed on the screen). Most often, BIOS settings do not cause any performance degradation and it’s not even worth messing with. But in rare cases, if critical parameters are incorrect, your computer may start to slow down.

If you doubt the correctness of the settings, but don’t know which ones you need to specify, you can use the option automatic settings optimal parameters“Load Optimal Settings” (the name of the function may be different depending on the manufacturer). After this, save all settings and restart your computer.

Disable everything unnecessary, control startup

Nowadays, almost every program tries to register itself in startup. And it's not much fun for your system. Gradually, programs in startup accumulate and they all need to be launched every time the system starts. Because of this, the computer takes a very long time to turn on and off. Additionally, after startup, all these applications remain in working order, devouring resources. Just look at how many unnecessary icons are on the taskbar (near the clock), do you really use them? Therefore, it is best to delete unnecessary applications, or at least disable autoloading for them.

To view all applications that start with Windows and disable unnecessary ones, simultaneously hold down two Win + R keys and in the next window write msconfig, then press Enter. A system configuration window will appear, now go to the startup section. There will be a list of startup applications here. Just uncheck all the ones you don't use. If something happens, the program can always be returned to startup by checking the required box. The main thing is to have an idea of ​​what these programs are and what their purpose is.

In the most extreme cases, you can disable the antivirus and the system will be slightly unloaded. Due to this, productivity will increase. But this should not be done when you are on the Internet or installing new programs, because there is a risk of infection with viruses.

We update drivers

This step may have the desired effect if installed outdated drivers or those that were installed with the system. The driver for the motherboard can have the greatest impact, although others also have a good effect on the speed of operation.

It is safest to manually update drivers. But the laziest can use special utilities that can determine for themselves necessary drivers, find them on the Internet and install them. For example, you can use Drover Checker.

Install the operating system corresponding to our PC

If you have powerful computer, with 2 GB of RAM and you are using Windows XP, then you should think about switching to the “seven”, after which you will immediately feel a positive difference. And if the computer has a dual-core processor and 4 GB of memory (or maybe even more), then you need to use 64-bit Windows 7. All this means that if the computer is powerful, then you should not hesitate to install an OS specially designed for such hardware, especially since more modern systems are much better at using resources compared to their predecessors.

And yes, avoid artisanal ones windows assemblies, such as Zver and the like. Use only clean, original distributions.

Cleaning the system from viruses

Don't pay attention to the fact that this item is number ten. In fact, this is one of the most common reasons for a slow computer. If you notice that your computer suddenly begins to “think” for a long time, immediately scan for malware. It is best to scan the system with a standard antivirus (for example, Kaspersky Anti-Virus), and then scan with additional anti-virus utilities such as Dr. Web CureIt, AVZ, etc. You will also be interested in how to remove a virus from your computer for free

That's all the main ways to increase the speed of your computer. In many subsequent articles, we will repeatedly touch upon the problem of system performance and all these recommendations will be considered in even more detail, with all the subtleties. Well, that’s all for today, if you have any questions, feel free to ask them in the comments to the article.

How to check the speed of your computer and Internet

Computer speed is a bit of a vague concept. I think it would be more correct to say performance, or the speed of the computer. And also, some people mean by this concept “the Internet speed of my computer.” So in this post I will try to cover both topics.

How to check your computer speed:

I think you yourself feel how fast your computer is when working with it. But since you came here, you probably want to know more numbers and comparisons.

Let's categorize methods for checking computer speed by degree of difficulty, starting with the easiest. Actually, they are all easy, so it would be more accurate to say from the fastest method.

First way:

This method works in windows 7. Using standard means windows we can find out the “Windows Experience Index”. It is calculated on an eight-point scale.

Let's go: Start\Control Panel\System and Security. In the “System” section, select “Windows Experience Index Check”

Or copy the following into the address bar of Explorer:

Control Panel\All Control Panel Items\Counters and Productivity Tools

And press Enter.

The overall rating is based on the lowest. For example, your computer configuration is set to 6.0, except for the hard drive. Let's say he gets 3.5. As a result, the overall rating is three and a half.

How can one judge here? I think if the score is four to five points, then there is nothing to worry about yet.

>Second method:

Using the task manager. Open the task manager using the key combination:

Ctrl + Shift + Esc

Go to the “Performance” tab. Here you can see the CPU load ( Central Processor) and Memory. You can also check various other data about the operation of your PC there.

Third way:

Using special programs. There are programs designed specifically for collecting information about a computer.

This is where there is a sea of ​​various data, numbers and tests. With the help of such programs you will get the most full information about your PC. What kind of programs are these?

1) SiSoftware Sandra - perhaps best program, if you need performance tests.

2) Everest - is more intended for analyzing the computer configuration, but the program also offers many tests.

How to check Internet speed on a computer:

It's not that hard to find out. There are sites specifically designed for this purpose:

Http://2ip.ru/speed/

Http://pr-cy.ru/speed_test_internet/

Http://internet.yandex.ru/

Follow one of the links and run the test. After some time, you will see the assessment results.

It is worth saying that the speed will be shown in Kbit/s or Mbit/s. How to convert these values ​​into the kilobytes and megabytes we are used to? Very simple. You just need to divide the speed values ​​by eight.

For example, if the provider claims that the speed on such and such a tariff is 40 Mbit/s, then this means that 5 MB will be downloaded per second. I hope I was able to help you. Good luck with your tests and revisions.

The need to check one or another component of a computer system may arise for various reasons. Some people just want to check the stability of the hardware, others are looking for the reasons for the device malfunction or achieving maximum performance. To do this you need a computer testing program.

Computer performance test online

Equipment inspection should always begin with collecting information about it. If you don't know exactly what components are installed and what software is being used, it will be more difficult for you to test your computer's performance. These parameters may indicate that to fix the problem you only need to change the operating mode (often happens in laptops) or update the driver.

To collect data, it is not necessary to download utilities; at the first stage, you can check online. The ma-config.com service is well suited for this, as it can also perform diagnostics. remote computer. For the tester to work, you first need to download and install the browser add-on. In terms of functionality, this online service is similar to the popular SiSoft Sandra. The report will provide you with complete data:

• about the manufacturer and model of the motherboard;
• chipset type;
• the amount of RAM, its operating frequency;
• processor models;
• BIOS data;
• about the USB bus and connected peripherals.

It will also be useful to check the performance of your computer on the network, for example, bandwidth. To do this, go to the website speedtest.net, click the Begin Test button on the website and the service will give you data on the speed of uploading data to the network and downloading it. This is one of the simple ways to check the “honesty” of the provider, whether it is cutting off your speed. According to the test results, it should match the data of your Internet service package.

How to check your computer for functionality

When errors occur on the computer’s hardware side, a person encounters failures in the form of a “blue screen of death”, spontaneous reboots, freezes and system slowdowns. Sometimes this condition is caused by a virus and should be checked full check to search for threats, but in the worst case this is due to hardware failures. First you need to find out which part is causing the problem, then determine what caused this behavior.

Checking RAM

Failures from this part of the computer are extremely rare, but when “overclocking” the system, it still happens that they burn out. A RAM test can be carried out using the Memtest+86 program. Test scheme:

1. Download the utility.
2. Create bootable USB flash drive.
3. Run the program from the flash drive and check the RAM.
4. The test will last indefinitely. If after several runs no errors are detected, then the RAM is working properly.

How to test a video card

More often, the desire to test a video adapter arises when you need to find out its maximum power. This is necessary to increase its performance beyond the factory settings in case of insufficient resources for new games. Sometimes such “overclocking” leads to breakdown, but this remains on the conscience of the owner. If you are buying a used part, then you should definitely know how to test the video card. This will allow you to avoid purchasing counterfeits, of which there are many. In addition, the test will help identify hidden failures at the chip level during operation.

To test a video card under load, FurMark is a good choice. It supports all modern operating systems, adapter models, and provides the most complete data on all parameters. First, you should download and install the utility itself; after launch, a window will open in which you should do the following:

1. By clicking on the CPU-Z button, you can get complete data on the video card: release date, operating frequency, amount of video memory, and RAM, model.
2. The Sensors tab displays the load and temperature of the device at the moment - these are the indicators when idle.
3. To test the adapter, click the Burn in Test button and then Go.
4. A graph with temperature data will appear, and a “hairy donut” will spin on the main screen.
5. The minimum to evaluate the performance of the card is to wait 15 minutes. If there are no freezes or reboots, the test can be considered passed.
6. Pay attention to the temperature, it should not be higher than 80 degrees Celsius. If the indicator is higher, there is a possibility that the part will behave unstable and at some point may burn out. The problem is either poor cooling of the fans or incorrect operation of the chipsets.

CPU stress test

To test CPU performance you can use CPU program Tester Pro. This program helps to test not only the CPU, but also other parts of the system. Used for testing at home and in commercial organizations. The program contains several modules that conduct CPU check, cache, memory, chipset.

Computer stress test creates heavy loads. This is done to check the extreme stability of parts and detect defective fragments. The program can conduct a test for 6 hours; if the system passes all the tests, then during normal use, failures are simply excluded. Before you test your computer using this method, think about whether you really need it. Stress is not normal for any processor and can cause it to fail.

How to check your hard drive

Another important part of a computer system is the hard drive or HDD. When it breaks, no utilities will be of much help, because you won’t be able to simply start the “machine.” As a rule, programs are used when you need to test a used part or identify possible causes of an operating system failure. The Victoria HDD utility is considered the most popular at the moment. After starting the program you need to:

1. If you have more than one hard drive, select the one you want to test in the right window.
2. First, check the SMART status in the second tab of the top menu. Click the Get SMART button. The results should contain the word GOOD. The hard drive temperature should be no higher than 40 degrees.
3. Next you need to select the Tests tab. On the right side of the screen, select the “read” item, under it check the ignore box and press the START button.
4. The program has rectangles of different colors. There should be no red ones at all, there may be 5-10 orange ones, but the fewer there are, the better. It is better if all sectors are gray.

After you have managed to test your computer for bad sectors, you can start replacing, restoring or erasing them. This will ensure more stable operation of the system. To do this, you need to select the required action instead of the Ignore item.

Many PC owners encounter various errors and malfunctions in their computer, but cannot determine the cause of the problem. In this article, we will look at the main methods for diagnosing a computer, allowing you to independently identify and fix various problems.

Keep in mind that high-quality diagnostics of a computer can take the whole day; set aside a day in the morning specifically for this, and do not start everything in the late afternoon.

I warn you that I will write in detail as for beginners who have never disassembled a computer, in order to warn about all possible nuances that can lead to problems.

1. Disassembling and cleaning the computer

When disassembling and cleaning your computer, do not rush, do everything carefully so as not to damage anything. Place components in a pre-prepared safe place.

It is not advisable to start diagnostics before cleaning, since you will not be able to identify the cause of the malfunction if it is caused by clogged contacts or the cooling system. Additionally, diagnostics may fail to complete due to repeated failures.

Unplug the system unit from the outlet at least 15 minutes before cleaning so that the capacitors have time to discharge.

Perform disassembly in the following sequence:

1. Disconnect all wires from the system unit.
2. Remove both side covers.
3. Disconnect the power connectors from the video card and remove it.
4. Remove all memory sticks.
5. Disconnect and remove cables from all drives.
6. Unscrew and remove all discs.
7. Disconnect all power supply cables.
8. Unscrew and remove the power supply.

There is no need to remove the motherboard, processor cooler, or case fans; you can also leave the DVD drive if it works normally.

Carefully blow out the system unit and all components separately powerful flow air from a vacuum cleaner without a dust bag.

Carefully remove the cover from the power supply and blow it out without touching the electrical parts and the board with your hands or metal parts, as there may be voltage in the capacitors!

If your vacuum cleaner does not work on blowing, but only on blowing, then it will be a little more difficult. Clean it well so that it pulls as hard as possible. When cleaning, it is recommended to use a soft bristled brush.

You can also use a soft brush to remove stubborn dust.

Thoroughly clean the processor cooler heatsink, having first examined where and how much it is clogged with dust, since this is one of the common reasons CPU overheating and PC crashes.

Also make sure that the cooler mount is not broken, the clamp is not opened and the radiator is securely pressed to the processor.

Be careful when cleaning fans, do not let them spin too much and do not bring the vacuum cleaner attachment close if it does not have a brush, so as not to knock off the blade.

After cleaning, do not rush to put everything back together, but move on to the next steps.

2. Checking the motherboard battery

The first thing after cleaning, so as not to forget later, I check the battery charge on the motherboard, and at the same time reset the BIOS. In order to pull it out, you need to press the latch with a flat screwdriver in the direction indicated in the photo and it will pop out on its own.

After this, you need to measure its voltage with a multimeter, optimally if it is within 2.5-3 V. The initial battery voltage is 3 V.

If the battery voltage is below 2.5 V, then it is advisable to change it. The voltage of 2 V is critically low and the PC is already starting to fail, which manifests itself in resetting the BIOS settings and stopping at the beginning of the PC boot with a prompt to press F1 or some other key to continue booting.

If you don’t have a multimeter, you can take the battery with you to the store and ask them to check it there, or just buy a replacement battery in advance, it’s standard and very inexpensive.

A clear sign of a dead battery is the date and time on the computer constantly disappearing.

The battery needs to be changed in a timely manner, but if you don’t have a replacement on hand right now, then simply do not disconnect the system unit from the power supply until you change the battery. In this case, the settings should not be lost, but problems may still arise, so do not delay.

Checking the battery is a good time to completely reset the BIOS. This resets not only the BIOS settings, which can be done through the Setup menu, but also the so-called volatile CMOS memory, which stores the parameters of all devices (processor, memory, video card, etc.).

Errors inCMOSoften cause the following problems:

• computer won't turn on
• turns on every other time
• turns on and nothing happens
• turns on and off by itself

I remind you that before resetting the BIOS, the system unit must be unplugged from the outlet, otherwise the CMOS will be powered by the power supply and nothing will work.

To reset the BIOS, use a screwdriver or other metal object to close the contacts in the battery connector for 10 seconds; this is usually enough to discharge the capacitors and complete cleaning CMOS.

A sign that a reset has occurred will be an erroneous date and time, which will need to be set in the BIOS the next time you boot the computer.

4. Visual inspection of components

Carefully inspect all capacitors on the motherboard for swelling or leaks, especially in the processor socket area.

Sometimes capacitors swell down instead of up, causing them to tilt as if they were just slightly bent or unevenly soldered.

If any capacitors are swollen, then you need to send the motherboard for repair as soon as possible and ask to resolder all the capacitors, including those located next to the swollen ones.

Also inspect the capacitors and other elements of the power supply; there should be no swelling, drips, or signs of burning.

Inspect the disc contacts for oxidation.

They can be cleaned with an eraser and after that be sure to replace the cable or power adapter that was used to connect this disk, since it is already damaged and most likely caused oxidation.

In general, check all the cables and connectors so that they are clean, have shiny contacts, and are tightly connected to the drives and motherboard. All cables that do not meet these requirements must be replaced.

Check that the wires from the front panel of the case to the motherboard are connected correctly.

It is important that the polarity be observed (plus to plus, minus to minus), since there is a common ground on the front panel and failure to observe the polarity will lead to a short circuit, which is why the computer may behave inappropriately (turn on every other time, turn off itself or reboot) .

Where the plus and minus in the front panel contacts is indicated on the board itself, in the paper manual for it and in electronic version manuals on the manufacturer's website. The contacts of the wires from the front panel also indicate where the plus and minus are. Typically the white wire is the negative wire, and the positive connector may be indicated by a triangle on the plastic connector.

Many even experienced assemblers make a mistake here, so check.

5. Checking the power supply

If the computer did not turn on at all before cleaning, then do not rush to assemble it; first of all, you need to check the power supply. However, in any case, it won’t hurt to check the power supply; maybe it’s because of it that the computer is crashing.

Check the power supply thoroughly assembled form to avoid electric shock, short circuit or accidental damage to the fan.

To test the power supply, connect the only green wire in the motherboard connector to any black one. This will signal to the power supply that it is connected to the motherboard, otherwise it will not turn on.

Then plug the power supply into the surge protector and press the button on it. Don't forget that the power supply itself may also have an on/off button.

A spinning fan should be a sign that the power supply is turned on. If the fan does not spin, it may be faulty and needs to be replaced.

In some silent power supplies, the fan may not start spinning immediately, but only under load; this is normal and can be checked while operating the PC.

Use a multimeter to measure the voltage between the contacts in the connectors for peripheral devices.

They should be approximately in the following range.

• 12 V (yellow-black) – 11.7-12.5 V
• 5 V (red-black) – 4.7-5.3 V
• 3.3 V (orange-black) – 3.1-3.5 V

If any voltage is missing or greatly exceeds the specified limits, then the power supply is faulty. It is best to replace it with a new one, but if the computer itself is inexpensive, then repairs are allowed; power supplies can be done easily and inexpensively.

The startup of the power supply and normal voltages is a good sign, but in itself does not mean that the power supply is good, since failures can occur due to voltage drops or ripples under load. But this is already determined at subsequent stages of testing.

6. Checking power contacts

Be sure to check all electrical contacts from the outlet to the system unit. The socket must be modern (suitable for a European plug), reliable and not loose, with clean elastic contacts. The same requirements apply to the surge protector and the cable from the computer's power supply.

Contact must be reliable, plugs and connectors must not dangle, spark, or be oxidized. Pay close attention to this, as bad contact often causes failure of the system unit, monitor and other peripheral devices.

If you suspect the quality of the outlet, surge protector, power cable of the system unit or monitor, then change them as quickly as possible to avoid damage to the computer. Do not delay or save on this, as repairing a PC or monitor will cost much more.

Also, poor contact is often the cause of PC malfunctions, which are accompanied by a sudden shutdown or reboot with subsequent failures on the hard drive and, as a result, disruption of the operating system.

Failures can also occur due to voltage drops or ripples in the 220 V network, especially in the private sector and remote areas of the city. In this case, failures may occur even when the computer is idle. Try measuring the voltage in the outlet immediately after the computer spontaneously turns off or restarts and watch the readings for a while. This way you can identify long-term drawdowns, from which a linear-interactive UPS with a stabilizer will save you.

7. Assembling and turning on the computer

After cleaning and inspecting the PC, carefully reassemble it and carefully check that you have connected everything you need. If the computer refused to turn on before cleaning or turned on only once, then it is advisable to connect the components one by one. If there were no such problems, then skip the next section.

7.1. Step-by-step PC assembly

First, connect the motherboard power connector and the processor power connector to the motherboard with the processor. Do not insert RAM, video card or connect disks.

Turn on the power of the PC and if motherboard everything is fine, the processor cooler fan should spin up. Also, if a beeper is connected to the motherboard, a beep code usually sounds indicating a lack of RAM.

Memory installation

Turn off the computer with a short or (if that doesn’t work) long press of the power button on the system unit and insert one stick of RAM into the colored slot closest to the processor. If all the slots are the same color, then just go to the one closest to the processor.

Make sure that the memory stick is inserted evenly until it stops and that the latches snap into place, otherwise it may be damaged when you turn on the PC.

If the computer starts up with one stick of memory and there is a beeping sound, then a code usually sounds indicating that there is no video card (if there is no integrated graphics). If the beep code indicates problems with the RAM, then try inserting another stick in the same place. If the problem continues or there is no other bracket, then move the bracket to another nearby slot. If there are no sounds, then everything is probably fine, continue further.

Turn off the computer and insert the second memory stick into the slot of the same color. If the motherboard has 4 slots of the same color, then follow the instructions for the motherboard so that the memory is in the slots recommended for dual-channel mode. Then turn it on again and check whether the PC turns on and what sound signals it makes.

If you have 3 or 4 memory sticks, then simply insert them one by one, turning the PC off and on each time. If the computer does not start with a certain stick or produces a memory error code, then this stick is faulty. You can also check the motherboard slots by moving the working strip into different slots.

Some motherboards have a red indicator that lights up in case of memory problems, and sometimes a segment indicator with an error code, the explanation of which is in the motherboard manual.

If the computer starts, then further memory testing occurs at another stage.

Installing a video card

It's time to test the video card by inserting it into the top PCI-E slot x16 (or AGP for older PCs). Don't forget to connect additional power to the video card with the appropriate connectors.

With a video card, the computer should start normally, without sound signals, or with a single sound signal, indicating the normal completion of the self-test.

If the PC does not turn on or emits a video card error code, then it is most likely faulty. But don't rush to conclusions, sometimes you just need to connect a monitor and keyboard.

Connecting a monitor

Turn off the PC and connect the monitor to the video card (or motherboard if there is no video card). Make sure that the connector to the video card and monitor is connected tightly; sometimes tight connectors do not go in all the way, which is the reason for the absence of an image on the screen.

Turn on your monitor and make sure it is selected correct source signal (the connector to which the PC is connected, if there are several of them).

Turn on the computer and a graphical splash screen and text messages from the motherboard should appear on the screen. Usually this is a prompt to enter the BIOS using the F1 key, a message about the absence of a keyboard or boot devices, this is normal.

If the computer silently turns on, but there is nothing on the screen, there is most likely something wrong with the video card or monitor. The video card can only be checked by moving it to a working computer. The monitor can be connected to another work PC or device (laptop, player, tuner, etc.). Don't forget to select the desired signal source in the monitor settings.

Connecting a keyboard and mouse

If everything is fine with the video card and monitor, then move on. Connect the keyboard first, then the mouse, one at a time, turning the PC off and on each time. If the computer freezes after connecting a keyboard or mouse, it means they need to be replaced - it happens!

Connecting drives

If the computer starts with a keyboard and mouse, then we begin to connect one by one hard disks. First, connect the second drive without the operating system (if you have one).

Do not forget that in addition to connecting the interface cable to the motherboard, you also need to connect the connector from the power supply to the drive.

Then turn on the computer and if it comes to BIOS messages, then everything is fine. If the PC does not turn on, freezes or turns itself off, then the controller of this disk is faulty and needs to be replaced or repaired to save the data.

Turn off the computer and connect the DVD drive (if any) with an interface cable and power supply. If problems arise after this, then the drive has a power failure and needs to be replaced; repairing it usually makes no sense.

At the end, we connect the main system drive and prepare to enter the BIOS for initial setup before starting the operating system. We turn on the computer and if everything is fine, move on to the next step.

When you turn on your computer for the first time, go to the BIOS. Typically used for this Delete key, less often others (F1, F2, F10 or Esc), which is indicated in the prompts at the beginning of the boot.

On the first tab, set the date and time, and on the "Boot" tab, select first boot device your hard drive with the operating system.

On older motherboards with a classic BIOS it may look like this.

On more modern ones with graphics UEFI shell a little different, but the meaning is the same.

To exit the BIOS and save the settings, press F10. Don't be distracted and watch the operating system load completely to notice possible problems.

After the PC has finished booting, check whether the fans of the processor cooler, power supply and video card are working, otherwise there is no point in further testing.

Some modern video cards may not turn on the fans until a certain temperature of the video chip is reached.

If any of the case fans does not work, then it’s not a big deal, just plan to replace it in the near future, don’t be distracted by it now.

8. Error analysis

This is where diagnostics essentially begin, and everything described above was just preparation, after which many problems could go away and without it there was no point in starting testing.

8.1. Enabling Memory Dumps

If blue screens of death (BSOD) appear while your computer is running, this can make troubleshooting much easier. A prerequisite for this is the presence of memory dumps (or at least self-written error codes).

To check or enable the dump recording function, press the “Win ​​+ R” key combination on your keyboard, enter “sysdm.cpl” in the line that appears and press OK or Enter.

In the window that appears, go to the “Advanced” tab and in the “Boot and Recovery” section, click the “Options” button.

The “Record debugging information” field should be “Small memory dump”.

If so, then you should already have dumps of previous errors in the "C:\Windows\Minidump" folder.

If this option was not enabled, then dumps were not saved, enable it at least now to be able to analyze errors if they recur.

Memory dumps may not be created in time during serious failures that involve rebooting or shutting down the PC. Also, some system cleaning utilities and antivirus programs can remove them; you must disable the system cleaning function during diagnostics.

If there are dumps in the specified folder, then we proceed to their analysis.

8.2. Memory dump analysis

To analyze memory dumps in order to identify what leads to failures, there is a wonderful utility “BlueScreenView”, which you can download along with other diagnostic utilities in the “” section.

This utility shows the files in which the failure occurred. These files belong to the operating system, device drivers, or some program. Accordingly, based on the file’s ownership, you can determine which device or software caused the failure.

If you cannot boot your computer in normal mode, then try booting into safe mode by holding down the “F8” key immediately after the motherboard’s graphical splash screen disappears or text messages BIOS.

Go through the dumps and see which files appear most often as the culprits of the failure, they are highlighted in red. Right-click on one of these files and view its Properties.

In our case, it is easy to determine that the file belongs to the nVidia video card driver and most of the errors were caused by it.

In addition, some dumps contained the “dxgkrnl.sys” file, even from the name of which it is clear that it refers to DirectX, which is directly related to 3D graphics. This means that it is most likely that the video card is to blame for the failure, which should be subjected to thorough testing, which we will also consider.

In the same way, you can determine that the fault is caused by a sound card, network card, hard drive, or some program that penetrates deeply into the system, such as an antivirus. For example, if a disk fails, the controller driver will crash.

If you cannot determine which driver or program a particular file belongs to, then look for this information on the Internet by the file name.

If failures occur in the sound card driver, then most likely it is faulty. If it is integrated, then you can disable it through the BIOS and install another discrete one. The same can be said about the network card. However, network failures can be caused by updating the network card driver and connecting to the Internet through a router.

In any case, do not make hasty conclusions until the diagnostics are completely completed; maybe your Windows is simply faulty or a virus has entered, which can be solved by reinstalling the system.

Also in the BlueScreenView utility you can see the error codes and inscriptions that were on blue screen. To do this, go to the “Options” menu and select the “Blue Screen in XP Style” view or press the “F8” key.

After that, switching between errors, you will see how they looked on the blue screen.

You can also find by error code possible reason problems on the Internet, but depending on the ownership of the files, this is easier and more reliable. To return to the previous view, you can use the “F6” key.

If the errors always include different files and different error codes, then this is a sign possible problems with RAM in which everything crashes. We will diagnose it first.

9. Testing RAM

Even if you think that the problem is not in the RAM, still check it first. Sometimes a place has several problems, and if the RAM fails, then diagnosing everything else is quite difficult due to frequent PC failures.

Running a memory test from a boot disk is prerequisite, so as to obtain accurate results in the operating room Windows system It’s difficult on a faulty PC.

In addition, “Hiren’s BootCD” contains several alternative memory tests in case “Memtest 86+” does not start and many more useful utilities for testing hard drives, video memory, etc.

You can download the “Hiren’s BootCD” image in the same place as everything else – in the “” section. If you don’t know how to properly burn such an image to a CD or DVD, refer to the article where we looked at it, here everything is done exactly the same.

Set BIOS to boot from DVD drive or use " Boot Menu"as described in, boot from Hiren's BootCD and run Memtest 86+.

Testing can last from 30 to 60 minutes, depending on the speed and amount of RAM. One full pass must be completed and the test will go around the second round. If everything is fine with the memory, then after the first pass (Pass 1) there should be no errors (Errors 0).

After this, testing can be interrupted using the “Esc” key and the computer will reboot.

If there were errors, you will have to test each strip separately, removing all the others to determine which one is broken.

If the broken bar is still under warranty, then take a photo from the screen using a camera or smartphone and present it to the warranty department of the store or service center (although in most cases this is not necessary).

In any case, it is not advisable to use a PC with broken memory and carry out further diagnostics before replacing it, since various incomprehensible errors will appear.

10. Preparation for component tests

Everything else, except RAM, is tested under Windows. Therefore, in order to exclude the influence of the operating system on the test results, it is advisable to do, if necessary, temporarily and the most.

If this is difficult for you or you don’t have time, then you can try testing for old system. But, if failures occur due to problems in the operating system, some driver, program, virus, antivirus (i.e. in the software part), then testing the hardware will not help determine this and you may go down the wrong path. And on clean system you will have the opportunity to see how the computer behaves and completely eliminate the influence of the software component.

Personally, I always do everything as expected from start to finish as described in this article. Yes, it takes a whole day, but if you ignore my advice, you can struggle for weeks without identifying the cause of the problem.

The fastest and easiest way is to test the processor, unless of course obvious signs, that the problem is in the video card, which we will talk about below.

If your computer starts to slow down some time after turning it on, freezes when watching videos or playing games, suddenly reboots or turns off under load, then there is a possibility of the processor overheating. In fact, this is one of the most common causes of such problems.

At the cleaning and visual inspection stage, you should have made sure that the processor cooler is not clogged with dust, its fan is spinning, and the radiator is securely pressed against the processor. I also hope that you did not remove it when cleaning, as this requires replacing the thermal paste, which I will talk about later.

We will use “CPU-Z” for a stress test with warming up the processor, and “HWiNFO” to monitor its temperature. Although, it is better to use for temperature monitoring proprietary utility motherboard, it is more precise. For example, ASUS has “PC Probe”.

To begin with, it would be a good idea to find out the maximum allowable thermal envelope of your processor (T CASE). For example, for my Core i7-6700K it is 64 °C.

You can find out by going to the manufacturer’s website from an Internet search. This is the critical temperature in the heat spreader (under the processor cover), the maximum allowed by the manufacturer. Do not confuse this with core temperature, which is usually higher and is also displayed in some utilities. Therefore, we will focus not on the temperature of the cores according to the processor sensors, but on general temperature processor according to the motherboard.

In practice, for most older processors, the critical temperature above which failures begin is 60 °C. The most modern processors They can also operate at 70 °C, which is also critical for them. You can find out the actual stable temperature of your processor from tests on the Internet.

So, we launch both utilities – “CPU-Z” and “HWiNFO”, find the processor temperature sensor (CPU) in the motherboard indicators, run the test in “CPU-Z” with the “Stress CPU” button and observe the temperature.

If after 10-15 minutes of the test the temperature is 2-3 degrees below the critical temperature for your processor, then there is nothing to worry about. But, if there were failures during high load, then it’s better to run this test for 30-60 minutes. If your PC freezes or reboots during testing, you should consider improving cooling.

Please note that a lot also depends on the temperature in the room; it is possible that in cooler conditions the problem will not appear, but in hotter conditions it will immediately make itself felt. So you always need cooling with a reserve.

If your CPU is overheating, check if your cooler is compatible. If not, then you need to change it; no tricks will help here. If the cooler is powerful enough, but can’t handle it a little, then you should change the thermal paste to a more effective one; at the same time, the cooler itself may be installed more successfully.

Among inexpensive but very good thermal pastes, I can recommend Artic MX-4.

It must be applied in a thin layer, having first removed the old paste with dry material and then with cotton wool soaked in alcohol.

Replacing thermal paste will give you a gain of 3-5 °C; if this is not enough, then simply install additional case fans, at least the most inexpensive ones.

14. Disk testing

This is the longest step after the RAM test, so I prefer to leave it for last. To begin with, you can conduct a speed test of all drives using the “HDTune” utility, for which I give “”. This sometimes helps to identify freezes when accessing the disk, which indicates problems with it.

Look at the SMART parameters, where the “disk health” is displayed, there should be no red lines and the overall disk status should be “OK”.

List of main SMART parameters and what they are responsible for you can download in the “” section.

Full test surfaces can be produced using the same utilities from Windows. The process may take 2-4 hours depending on the size and speed of the disk (about 1 hour for every 500 MB). Upon completion of the test, there should not be a single broken block, which are highlighted in red.

The presence of such a block is an unequivocal death sentence for the disk and is a 100% guaranteed case. Save your data faster and change the disk, just don’t tell the service that you dropped your laptop

You can check the surface of both regular hard drives (HDD) and solid state drives(SSD). The latter really don’t have any surface, but if the HDD or SSD freezes every time during the test, then most likely the electronics are faulty and need to be replaced or repaired (the latter is unlikely).

If you are unable to diagnose a disk under Windows, the computer crashes or freezes, then try doing this using the MHDD utility from the Hiren’s BootCD boot disk.

Problems with the controller (electronics) and the disk surface lead to error windows in the operating system, short-term and complete freezes computer. Typically these are messages about the inability to read a particular file and memory access errors.

Such errors can be mistaken for problems with the RAM, while the disk may well be to blame. Before you panic, try updating the disk controller driver or, conversely, returning the native Windows driver as described in.

15. Testing the optical drive

For check optical drive Usually it's enough to just burn a disc with verification. For example, using the “Astroburn” program, it is in the “” section.

After burning a disc with a message about successful verification, try copying its entire contents on another computer. If the disk is readable and the drive reads other disks (except for hard-to-read ones), then everything is fine.

Some of the problems I have encountered with the drive include electronics failures that completely freeze or prevent the computer from turning on, failures of the retractable mechanism, contamination of the laser head lens, and breakage of the head as a result of improper cleaning. In most cases, everything is solved by replacing the drive; fortunately, they are inexpensive and even if they have not been used for several years, they die from dust.

16. Body check

The case also sometimes breaks, sometimes the button gets stuck, sometimes the wiring from the front panel falls off, sometimes it shorts out in the USB connector. All this can lead to unpredictable behavior of the PC and can be solved by thorough inspection, cleaning, a tester, a soldering iron and other available means.

The main thing is that nothing short-circuits, as evidenced by a non-working light bulb or connector. If in doubt, disconnect all wires from the front panel of the case and try working on the computer for a while.

17. Checking the motherboard

Often, checking a motherboard comes down to checking all components. If all components individually work normally and pass tests, the operating system is reinstalled, but the computer still crashes, the problem may be with the motherboard. And here I can’t help you, diagnose it and identify a problem with the chipset or processor socket Only an experienced electronics engineer can do it.

The exception is the crash of a sound or network card, which can be solved by disabling them in the BIOS and installing separate expansion cards. You can resolder the capacitors in the motherboard, but, say, replacing the north bridge is usually not advisable, since it is expensive and there are no guarantees; it is better to immediately buy a new motherboard.

18. If all else fails

Of course, it is always better to discover the problem yourself and determine The best way solutions, since some unscrupulous repairmen try to pull the wool over your eyes and rip off your skin.

But it may happen that you follow all the recommendations, but cannot identify the problem, this has happened to me. In this case, the problem is most often in the motherboard or in the power supply; there may be a microcrack in the PCB and it makes itself felt from time to time.

In this case, there is nothing you can do, take the entire system unit to a more or less well-established computer company. There is no need to carry components in parts if you are not sure what is wrong, the issue will never be resolved. Let them sort it out, especially if the computer is still under warranty.

Computer store specialists usually don’t worry, they have a lot of different components, they just change something and see if the problem goes away, thus quickly and easily fixing the problem. They also have enough time to conduct tests.

If you want to overclock your computer, compare the system with others, or just show off your equipment, you need an assessment of your computer's performance. For Windows there are a huge number free applications for such testing.

Before running any test, make sure nothing is running on your computer. An application running in the background will slow down the test and skew the final results. Also, plan to run any test at a time when you won't need your computer, as some of these applications may take a while to run. certain time. The provided review will indicate the approximate operating time of each tool.

Stress test and benchmark your CPU with Prime95

Prime95 is a CPU stress testing program. It is especially popular among overclockers - users who improve computer performance by setting operating modes that exceed the nominal ones. This is a fairly old application, but it will work with almost any Windows version, from XP to Windows 10.

In addition, Prime95 is portable application, so there is no need to install it. You can simply download the Prime95 zip file, extract it, and then run Prime95.exe. If you don't want to create account, then immediately click the “Simple stress testing” button.

Typically, Prime95 suggests running a stress test right away, which is great for assessing the stability of your processor. If you are overclocking your computer, then this test will be especially useful. To start testing right now, click on “OK”. But keep in mind that such testing may take some time, perhaps long time. If you do not want to subject your computer to a stress test right now, then simply cancel its execution.

Whether you run or cancel a stress test, you can also run other tests by simply opening the Options menu and selecting Benchmarks.

Test results are measured by time: the lower the value, the faster the process occurs.

The tests may take some time to complete, especially if you are testing a multi-threaded processor with multiple cores, as the program must run multiple tests. This took about 10 minutes on the sample system being tested. If you are testing an overclocked system, compare the results before and after overclocking using the Prime95 test to see the difference in performance. You can also compare your test results with other computers on the Prime 95 website.

Perform comprehensive testing with Novabench

Novabench is a program for testing the central processor, graphics processor, RAM and some other indicators. Novabench is completely free. This program doesn't even have a trial version. And it works with Windows systems from 7 to 10.

After downloading and installing, launch it. You will see a simple window in which you need to click “Start testing”. Also in the “Tests” tab you can choose which ones to run.

Testing with this program is much faster than with many others. It took about a minute to evaluate the system under test, while in other programs this process took a lot longer.

Upon completion NovaBench testing displays the NovaBench benchmark - the higher the score, the better. The program also shows the results of each individual test. To compare your system's results with other users, click the "Compare these results online" button.

Gaming Performance Testing with 3DMark

NovaBench offers a simple 3D test, but for more intensive testing of your PC's performance, you may need a dedicated 3D testing tool. One of the most popular is 3DMark Futuremark. In principle, the free version provides a sufficient level for most people. The advanced paid version ($29.99) also includes some additional stress tests, graphic charts results and the ability to test systems with multiple GPUs. The free version is a massive and memory-intensive download that takes up almost 4 GB.

On the home page, click the "Run" button to test your computer. After this, as a rule, the so-called “Time Spy” appears for PCs with Windows 10.

3DMark runs tests in full screen mode and displays scenes that can be seen in games, only they are not interactive. Testing will take about 10-15 minutes. You'll then receive an overall performance score, as well as individual scores for your GPU and CPU. The higher the scores, the better. As with most similar programs, you can compare your results with the results of other users by clicking the “Compare result online” button.

To run other tests, simply click the Home button in the top left corner, select the Tests tab from the list that appears, and then scroll and select the one you want from the list of available benchmark tests.

Testing overall PC performance with PCMark

PCMark is a program developed by Futuremark - the same company that develops 3DMark, only PCMark focuses on overall PC performance. The free version doesn't include as many tests, but they can still be useful. The version you need depends on which Windows you are using:

• PCMark 10 is used for Windows 10 PCs.
• PCMark 8 is used for Windows 8 PCs.
• PCMark 7 is used for Windows 7 PCs.

And just as in the case of 3DMark, you can download a free basic version, or purchase a paid, but expanded version for $29.99. The paid version has some additional tests as well appearance graphs are worked out in more detail. Free option PCMark 10 weighs about 2 GB, so free up enough memory on your computer.

Launch PCMark, and on the Home tab, click “Run” to begin testing.

Testing will take about 15 minutes. At the bottom of the screen, the program shows the results of the testing that has already been done. In addition, when the video player and graphics are tested, additional windows. The results will appear immediately after testing is completed, and as with other programs, the higher your score, the better.

Scroll down the page and you will see the “Compare Online” option. By clicking on it, you will notice the comparative characteristics of your system with others tested.

Comprehensive performance assessment with SiSoftware Sandra

SiSoftware Sandra is another popular information and diagnostic application that includes benchmark utilities. SiSoftware offers paid versions, but the free version also contains tests that may be useful. To get a comprehensive overview of your system's performance, general diagnostics are suitable, but you can also run specific performance tests virtual machines, processor power management, network devices, memory and storage.

In the main window, go to the "Tools" tab and then double-click on the "Overall Performance Score" option. In addition, you can run a wide variety of benchmark tests for different subsystems of your computer.

Assessing overall performance involves testing your central and GPUs, bandwidth memory and file system performance. Make sure that the "Update results by running all" option is selected. control tests", and then click "OK" to start testing.

Sisoft also provides the ability to customize the mechanisms for displaying your rating. This setup is free, but requires registration by email. To avoid this, simply click the "Cancel" button and proceed to testing.

Warning: This program uses a number of fairly thorough tests, so this process may take a long time - most likely an hour or so. During testing, you will not be able to do anything with your PC, so run the program when you do not need your computer. During testing, it may seem that the computer does not respond to your commands and generally freezes. But don't worry: as soon as the program finishes testing, the results will be displayed on the screen and the computer will continue to operate normally.

Computer speed— the concept is a little vague. I think it would be more correct to say performance, or the speed of the computer. And also, some people mean by this concept “the Internet speed of my computer.” So in this post I will try to cover both topics.

How to check your computer speed:

I think you yourself feel how fast your computer is when working with it. But since you came here, you probably want to know more numbers and comparisons.

Let's categorize methods for checking computer speed by degree of difficulty, starting with the easiest. Actually, they are all easy, so it would be more accurate to say from the fastest method.

First way:

This method works in Windows 7. Using standard Windows tools, we can find out the “Windows Experience Index”. It is calculated on an eight-point scale.

Let's go: Start\Control Panel\System and Security. In the “System” section, select “Windows Experience Index Check”

Or copy the following into the address bar of Explorer:

Control Panel\All Control Panel Items\Counters and Productivity Tools

And press Enter.

The overall rating is based on the lowest. For example, your computer configuration is set to 6.0, except for the hard drive. Let's say he gets 3.5. As a result, the overall rating is three and a half.

How can one judge here? I think if the score is four to five points, then there is nothing to worry about yet.

>Second method:

Using the task manager. Open the task manager using the key combination:

Ctrl + Shift + Esc

Go to the “Performance” tab. Here you can see the load on the CPU (Central Processing Unit) and Memory. You can also check various other data about the operation of your PC there.

Third way:

Using special programs. There are programs designed specifically for collecting information about a computer.

This is where there is a sea of ​​various data, numbers and tests. With the help of such programs you will receive the most complete information about your PC. What kind of programs are these?

1) SiSoftware Sandra - probably the best program if you need performance tests.

Wiki link

2) Everest - It is more intended for analyzing the computer configuration, but the program also offers many tests.

How to check Internet speed on a computer:

It's not that hard to find out. There are sites specifically designed for this purpose:

http://2ip.ru/speed/

or

http://pr-cy.ru/speed_test_internet/

or

http://internet.yandex.ru/

Follow one of the links and run the test. After some time, you will see the assessment results.

It is worth saying that the speed will be shown in Kbit/s or Mbit/s. How to convert these values ​​into the kilobytes and megabytes we are used to? Very simple. You just need to divide the speed values ​​by eight.

For example, if the provider claims that the speed on such and such a tariff is 40 Mbit/s, then this means that 5 MB will be downloaded per second. I hope I was able to help you. Good luck with your tests and revisions.
