The computer freezes for no reason. Problems with OP. Reboot is the last resort

Freeze is a condition when the computer stops responding to keyboard input, mouse movements, i.e. absolutely does not react in any way to attempts to run a program, open or open a window. Today we’ll talk about what to do if your computer freezes. There are many reasons. Therefore, there is no universal solution to a computer freezing. All the reasons why a computer freezes can be divided into three groups: overheating, virus infection and hardware malfunctions. Now about each in detail.

Cause of freezing No. 1: overheating

Very often the computer freezes due to overheating of one or more nodes. Overheating can occur due to poor ventilation or a malfunction of a separate component. Solution: you need to check whether the radiators and coolers on the processor, video card or the motherboard itself are clogged with dust. If this is the case, then cleaning needs to be done.

Follow these steps:

1. Turn off your computer
2. Disconnect the 220V power cable and all other cables from the system unit.
3. Press the POWER button. This is necessary to discharge the capacitors. When you press the computer's power button with the 220V power cable disconnected, you can watch the coolers spin slightly.
4. Inspect the radiators and coolers of the video card, central processor, and all sorts of others, if any. Not only the central processor and video cards can overheat, but also other chipsets.
5. Unscrew the screw that secures the video card, press the video card lock (on the opposite side), disconnect the additional power (if available) and remove the video adapter.
6. Using a vacuum cleaner, a blower and a brush, remove as much dust, hair and other debris from the cooler and radiator of the video card as possible. The cooler should rotate easily and not catch on anything when rotating. If you feel the plastic cooler bushing overheating, or if you see that the plastic is melted, you need to replace the cooler. Unscrew the cooler from the radiator and take it to a computer store. They will help you choose the most similar or identical cooler.
7. In the same way, use a vacuum cleaner, a blower and a brush to remove dust from the cooler and radiator of the central processor. If you see that you cannot completely remove the dust, remove the radiator and cooler assembly from the CPU socket. In case of advanced contamination, it is recommended to remove the cooler from the radiator; carefully use a cloth soaked in alcohol to wipe the cooler impeller; remove any remaining old thermal paste from the heatsink and processor; rinse and dry the radiator; screw the cooler back onto the radiator; apply a thin layer of fresh KPT-8 thermal paste to the processor and cooler; and install the radiator and cooler assembly onto the socket mount.
8. Using a vacuum cleaner, a blower and a brush, carefully remove dust from other radiators, fans and, in general, from all surfaces of the boards and from all places in the system unit.
9. Install all components in place, connect cables and turn on the computer.
10. Use Everest to check node temperatures. Section “Computer” -> “Sensor”. For desktop computers, the CPU temperature when idle should not exceed 55 °C, the hard disk temperature should not exceed 50 °C

In addition to cleaning from dust, do not forget to check the serviceability of the fasteners - whether the heatsink fits tightly to the chipset or processor.

Cause of freezing #2: viruses or malware

Viruses cause freezes

These days, this is one of the most common reasons why a computer or laptop may freeze. Solution: you need to scan your computer for viruses. Check your PC with utilities and remove any malicious elements that are detected.

Reason for freezing No. 3: hardware problems

Physical hardware failures are another common reason why a computer freezes. As mentioned above, overheating can happen not only due to poor cooling. It happens that a processor or chipset fails and no matter how much you cool it, it will still glitch and get hot. Therefore, if after cleaning the dust you see that your processor is heating up, you need to check whether it has failed on its own. Ideally, you need to replace the component and see how another copy will work, whether the computer will freeze or work normally.

1. Check your RAM modules for failures using the program.
2. If there are errors in the operation of the RAM, clean the contacts of the modules using an eraser and alcohol. .
3. After cleaning the contacts of the RAM modules, repeat the test using Memtest 86+. If the problem persists, test each memory module separately. Perhaps one module has failed and can be replaced. Recommendations for selecting RAM modules.
4. Check the integrity of your hard drive using the program. If there are bad sectors, try to cure them. If there are more than three bad sectors, or if this is not the first time that a given hard drive has been treated by the HDAT2 program (i.e., a recurrence of bad sectors), it is recommended to replace the hard drive with a new one to avoid data loss. If you have cleaned your computer of dust and do not observe overheating, if you have removed all viruses, if you have checked the RAM modules and hard drive and found no problems, but the computer still freezes, we advise you to contact a service center to receive qualified assistance from specialists.
5. If there are no bad sectors on the hard drive, replace the SATA cable. Often damaged cables cause freezes, spontaneous reboots and other unpredictable computer behavior.

Reason #4: no disk space

Check to see if your computer is freezing due to the disk running out of free space. In order for this to happen, you don’t need to watch how the disk is filled at all. Most often this happens to beginners who copy movies and save photos to their desktop and do not know how to clean their computer from debris. We recommend following these steps:

1. Check how much space is left on the drive where Windows is installed (usually drive C). For Windows 10 to work properly, you must have at least 15 gigabytes of free space. If you run out of space completely, your computer may freeze. So, if there is less than 15 GB of space on the C: drive, move on to the next step.
2. Remove garbage (cache, temp, temporary browser files) with the program.
3. Make sure that there are no heavy files saved on your desktop, such as archived photos, music, videos, etc. Move such files to another drive.
4. You can (such as Music, Videos, Documents) to another drive.
5. If all these steps do not help, you need to expand the system disk using appropriate programs. Read more about this in.

More rare causes of computer freezing

Keep in mind that there are other, less common reasons why your computer often freezes or slows down. Among them:

Often, users reinstall Windows if the computer starts to slow down. This method may be effective, but it requires a lot of time and does not eliminate hardware difficulties. To restore the previous performance, it is necessary to carry out diagnostics and understand the reason why the system freezes. As a rule, the reason is one of the following.

1. High CPU and RAM load

If the system hangs, check the current level of system resource usage. It is not necessary to use additional programs for this. A tool that helps you understand your resource consumption is included with Windows. To open it, simultaneously press three buttons on your computer keyboard - “Ctrl + Shift + ESC”. You can also use the combination “Ctrl + Alt + DEL”, and then select “Task Manager”.

In the manager window, click on the second tab - “Performance”. Here are graphs of the current load of the central processor, RAM, and hard drives. Switching between sections is done by clicking on their name in the left column. If the load on one or more hardware components is constantly at its limit (the average value is 80-100%), the computer slows down precisely for this reason.

Important! More detailed information on the reasons for the load on hardware elements is available through the resource monitor. It opens from the link at the bottom of the window.

There are two main ways to resolve hangs caused by insufficient system resources. The first is to increase the amount of RAM, replace the processor or hard drive. To replace an HDD, you only need a new disk of the appropriate size with the appropriate interfaces. Before this step, you should make sure that the reason why your PC is slowing down is a hard drive failure. This can be done using the Victoria or MHDD utilities.

Replacing the processor or RAM on a laptop is a more time-consuming and expensive process. As a rule, motherboards for portable devices have high requirements for hardware compatibility. To find out which components are suitable for your computer, go to the manufacturer's website. It is important that the quality characteristics of new parts differ significantly from the characteristics of old ones. This will allow you to achieve a significant increase in productivity.

The second way to solve such problems is to free up existing hardware resources. You don't need to buy new parts to use it. It will be enough to find the reason why your PC is slowing down and close unnecessary applications running on the computer in the background.

2. Running unnecessary background programs

You can also find out which applications are currently running in Windows in the “Task Manager”. Go to the first tab - “Processes”. It is most convenient to sort the list by the use of the component that is most loaded. For example, if RAM is often used at 80% or more, click on the corresponding column heading. Processes will be listed starting with those that consume the most memory.

If you need more detailed information about processes, add additional columns to the table. Right-click any column header and select the section you want to add. These can be the columns “Publisher” (program developer) and “Type” (background process, application, Windows process). To end the program, select “End task” in its context menu. You can also mark a line and then press the “Del” button on your keyboard.

3. Unnecessary applications in Windows startup

If you yourself did not launch the unnecessary processes found in the previous step, the reason for their appearance is the automatic loading when Windows starts. The further operation of such programs can be unnoticeable, since they are minimized to the tray or run in the background. But utilities consume their share of system resources even in such cases. This can cause the device to freeze, the PC to slow down or even reboot.

Autorun of some utilities is enabled immediately after installation. You can check the current startup list on the fourth tab of the task manager. By default, the following columns are enabled in the table:

• Name — program name;
• Publisher - the name of the company that developed the application;
• Status - current status of automatic start;
• Impact on startup - load on the system, causing it to freeze every time it starts.

Advice! To disable the automatic launch of an application when the operating system boots, right-click on its name and select “Disable”.

4. Infecting your computer with viruses

The cause of Windows freezing and slow operation may be virus activity. A number of viruses perform tasks of indexing or encrypting data on the hard drive, as a result of which the PC slows down. Other unwanted applications load the network by sending information over the Internet. A computer freezing in this case is not as critical as the main losses caused by the virus.

To avoid infection, do not open suspicious files sent to you by strangers. Install utilities only from trusted sources - official websites and the Windows store. Use antivirus programs with active protection. They scan your computer in real time and prevent malicious code from executing. Examples of such antiviruses:

• ESET NOD32;
• Avast;
• Kaspersky Anti-Virus;
• Dr.Web;
• AVG Internet Security.

If you experience regular freezes and suspect an infection, check Windows using a full scan. Scanning all files takes considerable time, however, only this will identify all real and potential security threats. If the antivirus detects files containing a potential threat, send them for online scanning through the VirusTotal service. It will help you scan a specific file with several anti-virus utilities at once to more accurately identify malicious code.

5. Overheating when the computer is running

Freezing or interruptions in the operation of the device may be caused by overheating. If the system gets too hot, it may slow down or turn off automatically. Shutting down occurs to avoid damage to computer parts, so the problem of overheating should not be ignored. You can check the current temperature of system components using the following programs:

• Speccy;
• HWMonitor;
• AIDA;
• SpeedFan;
• Open Hardware Monitor;
• OCCT.

Overheating is most often caused by poor ventilation of the internal components of the device. Fans used to cool parts become contaminated with dust and small particles. As a result, the efficiency of their further operation decreases, since cold air is not able to freely pass through the layer of contamination on the blades. Dust can also settle on radiators and the boards themselves.

The first thing you need to do if your computer constantly freezes is to find out the cause of this problem. Of course, it’s quite difficult to do this offhand, but the way to solve this problem depends on the cause of the freeze.

Let's look at the most common reasons why a computer may freeze. I will also tell you what needs to be done in each specific case to solve the problem.

1. Resource-intensive programs or insufficient computer power.

First, you need to determine which program, out of several running ones, is causing the computer to freeze. By pressing the combination Ctrl+Alt+Del (an alternative to Ctrl+Shift+Esc) we call up the “Task Manager”. It shows very well how all running programs behave. The mark “Working” indicates the normal flow of the process, and “Not responding” indicates a failure in the program. If one or two programs are designated this way, most likely the reason the computer constantly freezes is in them. The solution is to give the command “Cancel task”. In some cases, the computer does not respond immediately, but there is no need to rush, it is better to wait a couple of minutes and then repeat the command. Sometimes, when the computer “does not listen,” you select a frozen program with the mouse cursor, click the right mouse, and select the item in the drop-down menu - go to processes. You are already “killing” this program in the processes.

After the frozen program is closed, you need to determine for yourself the importance of this program. Many programs are necessary for work or regular communication. If such a program constantly freezes the computer, you need to select an analogue, for example a program from another developer, return to an earlier version of the program, or simply find a comprehensive solution to perform this task.

Remember: double-clicking the Ctrl+Alt+Del combination reboots the system, which means that many of your work (unsaved texts) may be lost. If the computer does not respond to the “End task” command, you need to reboot the computer using the “Shut down” command. Unlike double pressing Ctrl+Alt+Del, this command works more “softly”: all normally running applications will be closed, saving data, and only then the computer will reboot.

2. Computer overheating.

A lot of dust often accumulates inside the computer, and this interferes with normal heat transfer and, as a result, the computer overheats and constantly freezes. If you open the monitor cover and see that the radiators are covered with a “blanket of dust”, you should know that this is the main reason why the computer freezes. What can be done in this case? Wait until more or less normal operation is restored, save all documents and turn off the computer.

After this, you need to open the case and carefully clean the boards. This can be done using the softest brush and a vacuum cleaner at low speed, or simply brush off the dust with a soft brush. In any case, this operation should be carried out as carefully as possible. In the future, to monitor changes in temperature conditions, you can use special programs such as SpeedFan or Everest - they will report if any part of the system unit is on the verge of overheating. If your computer constantly freezes and you are sure that the reason is overheating, you should install additional fans.

By the way, sometimes the problem with constant freezing is solved by cleaning oxidized contacts. To do this, you can use a special solution or do it with a regular eraser.

It is worth adding that overheating is one of the simplest reasons for a computer to freeze. I remember when I bought my first computer, the assemblers forgot to connect power to the fan blowing the processes. And naturally, my computer turned off every half hour, hour.

3. Defragmentation is necessary.

Regular installation of new programs and intensive computer work leads to the fact that the computer constantly freezes. What to do? The solution to the problem in this situation is very simple - run defragmentation. To do this, right-click on the “Disk C” icon (or another disk with which you often work) and in the window that appears, open the “Properties” option. At the top we find the “Service” tab and, opening it, select “Disk Defragmentation”. When this operation is completed, the computer will issue a report. If this was the reason for the constant freezes, the crashes should stop. It is advisable to carry out defragmentation regularly.

It is worth adding that, as a rule, Defragmentation somewhat optimizes and speeds up the operation of the computer, but does not eliminate the reasons for its freezing.

4. Viruses.

Unfortunately, none of the existing antiviruses can guarantee 100% protection against pest programs. If your computer constantly freezes, the first thing you need to do is check your system for viruses. We update the installed antivirus database and perform a standard scan. If nothing is found, but the problem with freezing has not disappeared, then you should install an antivirus from another developer, update it and re-check for viruses. This approach gives a clearer picture. Scanning with Nod, Avast, Dr.Web CureIt and other well-known antivirus programs gives good results.

The most affordable treatment method is:

1. Download Dr.Web CureIt.
2. Boot the computer in safe mode (when booting the computer, you need to press F8 and then select safe mode).
3. Conduct a full scan of the computer.

5. Problems with hardware - breakdown of components.

In addition to the situations described above, constant freezing of the computer may cause a malfunction of one of its components. It is difficult to determine offhand what may break and be the cause of regular failures. But if, for example, the arrow or cursor slows down, then first of all you should check the functionality of the mouse; if the screen goes blank, check the state of the video card. By the way, constant freezes along with frequent system reboots indicate more serious failures, for example in the hard drive, RAM or one of the motherboards. Only a professional at a service center can solve this problem.

The simplest thing you can do is open the computer lid, if it is not a laptop, and see if all the fans are spinning. If a fan fails, for example a fan on a video card, then the video card will overheat and slow down the computer.

In reality, there are many more reasons for the problem when the computer constantly freezes and something needs to be done, but only service center employees can clearly identify many of them. If the solutions described do not solve the problem and the computer continues to freeze, you need to contact a specialized service.

Video.
To better understand the reasons why your computer freezes, you can watch the following video.

Deadly, Windows 7 stops responding to any commands, it’s even impossible to open the task manager? Such problems appear quite rarely. It must be said that a computer is a rather complex system, and its performance depends on a huge number of factors. The article will discuss the main ones. After reading, you will learn to deal with most of the problems that lead to “freezes” on your own.

Viruses

The first answer to the question of why the computer freezes is the simplest and most common. It is quite possible that uninvited guests have settled on your computer and are well camouflaged. Typically, viruses not only threaten the security of the system, but also significantly load computer resources. Sometimes this load leads to

Everyone knows how to deal with such a scourge. It’s enough just to install any anti-virus program, update its databases to the latest ones and run the full one. It didn’t help - call and check the processes to see if there are any suspicious ones. It would also be a good idea to look into startup by entering the name of the utility “msconfig” in the “Run” window.

However, if the computer freezes tightly after turning on, it will not be possible to install new software, much less check the PC. In this case, use any antivirus distribution that can create a bootable USB flash drive or CD.

Overheat

When releasing each new device model, manufacturers try to make it more sophisticated than the previous one. And this requires more power. The latter, in turn. increases heat generation. For some time, the standard cooling system copes with its job, but after a while its effectiveness decreases - as a result, the computer freezes completely. What to do if such a disaster happens?

Dust, which cannot be removed, clogs into radiators and interferes with air circulation. As dust settles on the cooler, it slows down the rotation speed of the propeller. Previously, such problems led to device failure. Today, fortunately, computers have become smarter; there will be no endless or video card. Modern devices have the ability to communicate with the motherboard, entrusting it with temperature control responsibilities. As soon as the values ​​reach a critical point, the controller first tries to unscrew the cooler screw, but if this does not help, the system slows down the device, reducing the voltage. Soon the computer freezes completely.

To prevent such troubles from happening, remember a few simple rules:

Very often, because of this problem, the computer freezes in games or other graphic applications. To check how hot your computer components are, you can download a program. Fortunately, there are a huge number of similar ones on the Internet.

RAM problems

RAM is the most important element of a computer, which has a very large impact on its performance. Normal operation of RAM depends on compatibility with the motherboard, BIOS, and other installed memory sticks. A minor glitch, the smallest manufacturing defect - and the computer freezes tightly when turned on, not wanting to work even at low performance.

If you are going to increase or change the RAM, fully study its characteristics, go to the website of its manufacturer and the motherboard manufacturer in advance, study what speeds are supported, what tests have been carried out and whether it is recommended to use the devices together.

If the computer freezes until the configuration is changed, you can check whether the RAM is faulty using Windows 7. Just click on the “Start” button and type “memory checker” in the search column. During the procedure, the program will display all errors if any were found. There is only one recommendation: if there are errors, change the memory.

HDD instability

A hard drive is a device on which absolutely all data (both user and system) is stored. Accordingly, Windows accesses it all the time, reading and writing does not stop for a minute. This means that system performance directly depends on the speed of this component. Over time, “broken” clusters and unreadable areas may appear on it, which will lead to system failures. Often, because of this problem, the computer freezes on the Internet, because while surfing the browser constantly records and deletes many small files.

Repairing a broken HDD

If the HDD is worn out, you need to check it with special software tools that will find all damaged sectors and mark them as non-working. The OS will stop using “bads” and stop freezing. To check, launch the command line by entering the name of the program in the “Run” window - “cmd”. In it, run the command “chkdsk [drive letter]: /f /r” for each partition.

Experienced users can determine the status of the HDD by the sound of its operation. If it starts clicking or whistling, the equipment is most likely faulty and needs to be replaced. Be careful, often, if a hard drive begins to “crumble”, it will soon fail, and it is very difficult to recover data from such a device. Also, if the computer freezes after turning on, there is a high probability of wear on the hard drive.

Incorrect BIOS setting

If the computer freezes after turning on, very often the reason for this behavior of the system is incorrect BIOS settings. Someone may think that an ordinary user should not even try to fix something, he should contact a professional. But still the computer freezes tightly - what to do if there is no way to call a specialist?

If you approach BIOS configuration with care, even a beginner can handle this procedure. Learn complete information about your computer, and especially about the motherboard. Usually such data is easily found on the manufacturer’s official website. Find out which parameters are most important and what they are responsible for. When using the BIOS setup utility, never change many settings at once. First change a few, reboot, check the computer. Only then continue editing. A special mention should be made of the item that is in every BIOS - “Load Fail-Safe Defaults”. It brings all parameters to optimal - in the opinion of the developer.

Sometimes you can download and install a new BIOS version on the motherboard manufacturer's website. Never refuse such a procedure. Updates often fix critical bugs and improve stability. It is likely that after installing the new version, the freezes will disappear. The main thing is to read the instructions in advance.

Windows Services

The operating system runs a large number of services all the time, either enabled by default or added during operation. The system can work fine without most of them. If some service does not respond or takes up too much processor time, the computer freezes.

To see which of them are in the system and which are running, open the administration window ("Start" - "Control Panel" - "Administrative Tools") and double-click the "Services" shortcut. To get comprehensive information about a particular service, double-click on its name.

First of all, pay attention to those that start automatically. The loading method is indicated in the “Startup type” column. There is only one editing rule - if you do not understand the description, do not disable the component, but find out more about its operation from the Internet. Try to check the stability of the system after each individual manipulation.

Processes and programs

Each program starts its own process (sometimes even more than one), if it enters an endless loop or malfunctions, and the computer does not always freeze completely; Windows 7 still tries to independently cut off oxygen to non-responsive components. It is very easy to identify a frozen element - it usually takes up the lion's share of RAM and almost all the processor time.

Solving the problem using the task manager

You can view the list of running processes in the task manager window. Press the combination “CTRL+ALT+DEL” on your keyboard. If you are sure that some program does not carry a payload, but at the same time takes up 90-100% of the processor time, feel free to terminate it (by pressing “DEL” on the keyboard or by calling the context menu). You can also go to the location where the program is stored from here. This will be useful if you do not understand exactly what you are interrupting.

Checking processes is not always the best solution, but this procedure can often help if the computer periodically freezes. Remember that some programs can load the processor one hundred percent during the most active phases of their work. However, a frozen utility will not stop using maximum resources, and one that performs its functions without failures will again go into passive mode after some time. Also, do not try to end the process called System Idleness. It is used to poll other programs and system resources, and the variable in it does not display the processor load, but just the remaining free power.

Over time, Windows OS becomes less fast and many people ask the question “why does my Windows 7 computer freeze?”
This is primarily due to the accumulation of various files in the system, including unnecessary ones. But sometimes the cause of freezing can be something more serious.

System problems

Let's consider the reasons that are associated with the incorrect operation of the system or its individual elements. It is worth noting that the solution and screenshots are presented using Windows 10 as an example, but are also suitable for other versions of the OS.

Autoload overloaded

The problem is especially acute for older PCs that have poor performance. When Windows starts, programs from startup automatically start almost simultaneously and place a heavy load on the computer. Further troubleshooting is shown using Windows 10 as an example, but it is also suitable for other versions of the OS.

To solve the problem:

System clogged

This happens if the system has not been reinstalled on your computer or laptop for a long time. Residual files and garbage accumulate and clog the OS.

You can solve this problem using CCleaner.

After these steps, the system will work faster.

Viruses and firewall

Everyone knows that viruses harm the system and can slow it down or damage important files.

To check the system:

But the problem may not only be with the virus itself, but also with the firewall. This is a technology that prevents malicious actions coming from the network against the PC.

The standard Windows firewall can greatly slow down the system, working simultaneously with the installed antivirus.
To disable it:

Important! Only disable the firewall if you have an antivirus installed.

Driver incompatibility

This primarily applies to laptops. After updating the system, drivers often become irrelevant. This leads to unstable operation of individual components, for example, a video card or chipset. Accordingly, the operation of the entire system slows down.

To update drivers:

Attention! Driver problems often result in high CPU load. (You can check it in the task manager)

System files error

When OS failures occur, system files suffer. This leads to errors in the system, registry and disk. To fix the problem:

1. Download CCleaner from the website and install.
2. Launch the program.
3. Open the Registry tab and run a search for problems.
   
4. Once complete, click “Fix Selected.”
   
5. Close the program and go to Explorer.
   
6. Select the system disk by clicking on it and open “Properties”.
   
7. “Tools” → “Check”, and when finished, click “Optimize”.
   
8. Restart your computer or laptop.

In case of a large number of errors, it is better to completely reinstall the OS.

Hardware problems

If fixing system problems did not help, then this indicates a more serious problem.

Important! Only a specialist can perform a complete check of your computer components; you do all actions at your own peril and risk.

Let's look at what problems there are with components.

HDD

The main cause of freezes is almost always the HDD. This is a very fragile element that can be damaged even from a small fall. You can determine the primary signs yourself.

1. If you hear a crackling sound, intermittent beats, or knocking, this indicates a malfunction of the disk device.
2. The problem disk reveals itself by the fact that when it freezes, the indicator light on the system unit indicating the HDD is constantly on.

In such cases, it is necessary to replace the device or send it to a specialist for repair.

Almost no one pays attention to it, but it is also one of the most popular freezing problems. This is due to the fact that over time the power supply depletes its resource. As a result, it is not able to support the declared power, and the voltage on the power lines does not meet the standards.

The processor and other components do not receive enough power, which leads to unstable operation. Replacing the old unit in such cases can fix the problem with system freezes.

Random Access Memory (RAM)

Braking may be due to a lack of RAM, or in cases of its malfunction.

The problem can be identified by the following signs:

1. Freezes during copy and paste operations.
2. Freezes when moving files, especially large ones.

In such cases, you can try to test the system by inserting RAM from another PC or laptop.

Processor (CPU)

This problem is primarily associated with overheating of the processor or insufficient power. During heavy overloads, the temperature rises and causes the PC to slow down or shut down.

Important! Every six months you need to clean the components from dust and replace the thermal paste - this prevents overheating. The article “Relieving your computer of brakes: resource diagnostics, mechanical cleaning, optimization of Windows 10” contains detailed instructions.

Advice! Check the instructions for your processor to determine what temperature is considered optimal.
