Blue screen appears on Windows 7. Check your computer's internal hardware. Waiting for failure data to appear

Quite often, many people experience problems associated with personal computers. The blue screen that appears after turning off and on the computer is especially annoying. This screen reports a specific error. To understand what kind of error you have encountered, you can enter the hexadecimal code in the Microsoft database that is displayed in the message. Chances are that you will receive some advice on how to solve your problem. So, let's say you experience a blue screen of death. What to do? First, you need to figure out what errors can cause it to appear.

Reasons for the error

Most often, basic hardware problems are associated with the HDD not working correctly. Problems with memory and processor can also cause a blue screen. Software errors are usually caused by viruses, rootkits, or drivers that were not installed entirely correctly. What can cause a blue screen of death to appear? The reasons mainly lie in hardware errors. A large number of personal computer hardware components can cause this error due to malfunction. It is worth considering the main components that cause malfunctions.

What to do if problems arise due to the HDD

The hard drive is one of the most important elements of every personal computer. It stores a large amount of data and the operating system itself. Very often, the Blue Screen of Death appears due to damaged sectors or due to defects that may be present on the hard drive. They contribute to damage to the operating system itself, thus affecting its performance. Problems may be related to the read head - this problem occurs mainly when the HDD reaches five years of age. Based on statistical data, problems in this situation arise due to overheating of the disk. So, blue screen of death: what to do if the problem is in the hard drive?

In order to get rid of problems, you need to use special software. They can move idle sectors to an HDD location that is not in use. In addition, if the damage to the hard drive is too great, it can be replaced with a new one. In this case, you will also need to reinstall the operating system. In this situation, you need to copy all your important documents to an external drive so that they are not damaged by the error that causes the Blue Screen of Death. What to do if the hard drive is not to blame for the problem? It is worth paying attention to memory.

Errors with memory and processor

The causes of problems may also be related to PC memory. For a blue screen to appear, it only takes one module to fail. The cause of this damage is mainly overclocking, which uses more voltage than necessary. In addition, elements of the electrical circuit can fail under the influence of heat. Poor quality parts can also cause an error that results in a Blue Screen of Death. What to do in this case? To overcome the problem, you should reduce the input voltage supplied to the memory chips. This should be done in the BIOS. If after this the problem continues to occur, then you should consider buying a new memory module. The processor can also cause a blue screen if it fails. In order to get rid of this problem, you should immediately change the part.

Software errors

The cause of a blue screen may be driver malfunctions or viruses. In the first case, they simply need to be reinstalled. If this does not help, then you should find those programs that are optimally suited to your computer. If errors occur due to malicious programs, you should seek help from a special utility - an antivirus.

Conclusion

Don't despair if you get a blue screen. You just need to find the cause and eliminate it. Microsoft databases can help in her search. Good luck in solving problems with your personal computer.

The screen of death is caused in Windows 7 by system errors classified as critical. The OS freezes and the user's latest changes are not saved.

The situation is not the most pleasant, but it is often found in computers with the “Seventh” modification of the system.

There is no general algorithm of actions to eliminate this problem, since it depends on the causes that caused it. Below are specific recommendations that should be taken to effectively resolve the situation.

Why does the death screen appear?

All the abundance of reasons causing BSoD are classified into two large parts:

Software;
Hardware.

The first includes failures in system services, incorrectly installed software (including drivers that ensure the normal functioning of the equipment), virus infections of the PC, software conflicts, etc.

The second part of the reasons that cause a blue screen in computers running Windows 7 lies in the hardware. The record holders for popularity are such important PC components as the hard drive and RAM.

Often, after a user installs an additional RAM stick into a PC or due to poor contact in the slot, a blue background with white letters will immediately greet the computer owner. It is also not uncommon for problems with the hard drive to cause critical errors and OS freezes.

The blue screen itself in Windows 7 is of an informational nature. Its text contains recommendations for troubleshooting and notifies the user of the specific error codes that caused it to occur.

That is why you need to carefully study all the inscriptions displayed by the screen of death. By rewriting or remembering the error codes from the bottom of the screen, you can surgically accurately diagnose and quickly get rid of the problem.

Unfortunately, often the user does not have time to familiarize himself with the output report, so this guide begins with a technique for canceling the automatic restart of the PC after an error occurs.

Computer settings

If the user did not have time to capture the necessary information from the screen, then a little PC setup will be required.

After this, once you know the code, you can use it to find an effective “medicine” that can cure your iron friend.

You need to do the following:

It is recommended to study the meaning of the error code on the resource “bsodstop.ru”. For example, “0x0000004e” may appear due to an incorrectly installed driver.

To find out exactly what software caused problems in the system, you should use the BlueScreenView application, which automatically identifies files that cause a critical error. The user only needs to install and open the application.

Based on the detected file, you can find out for which equipment you need to reinstall the drivers. From the above figure we can conclude that there are difficulties with the graphics accelerator, since “ati2dvag.dll” is associated with the video card.

In this case, installing the correct software for the video accelerator will allow you to get rid of the screen of death.

After reinstalling the driver, you need to restart the PC. If the problem could not be corrected, then it means that there are other reasons.

Often the error occurs after updating or installing a new program, and the best way out of the situation is to roll back the OS.

Rollback

A new program or game is also often the culprit of system failures. In order to return the OS to a working state, it is necessary to perform the following sequential steps:

Installing OS updates

Specialists from Microsoft do not stand aside and are making their efforts to troubleshoot problems that cause BSoD.

They continue to support the already outdated “Seven” and release upgrades that include “fixes” that correct system errors that cause blue screens.

To update you will need to do the following:

The next most popular cause of problems is a simple lack of memory in the system partition of the hard drive. Checking this version will not take much time.

Low memory

On the official resource of the Windows 7 developer it is written that for its functioning it requires at least 100 Mb of free space on the system volume, however, practical experience has proven that for the “Seven” to work normally, it is necessary to keep a fifth of the system volume free.

To make sure there is enough space in the partition, you just need to open “Computer” in Explorer.

After making sure that there is enough space for the OS to function, you should proceed to analyzing the presence of system errors through the event log.

Event log analysis

To do this, you need to take the following steps:

Antivirus and viruses

Often, simply disabling the antivirus program will resolve the problem. If, after deactivating the security application, the blue screen no longer appears, then you will need to completely remove the antivirus.

Malicious utilities also cause critical errors, and regular scanning of your PC for their presence is required. Many antivirus software developers have versions of programs that operate from removable media.

For example, "AVZ". By recording the application onto a CD or flash drive, you can treat your PC from malicious utilities.

BIOS

Incorrectly entered parameters in the BIOS also often cause crashes. You can correct the situation by resetting the BIOS settings to the initial state - “default”.

Equipment

A simple inspection of the wear of the cables and the correctness of their connection sometimes allows you to quickly identify the cause of the failure.

If the user has the appropriate experience, it is necessary to open the system unit (SU) and check the connections of all computer components.

For example, when, based on the results of a careful review of the information displayed on the blue screen itself, it is determined that there is no access to RAM, you will need to perform the following actions:

Turn off PC;
De-energize the computer by disconnecting it from the power source;
Remove the SB cover and disconnect the RAM boards;
Wipe the contacts with a dry cloth and insert the equipment into place;
Start PC;
Make sure the problem is resolved.

Similar measures can be taken with other PC components, for example, with a hard drive and sound and video cards. If there is no positive result, then this component may fail and will need to be replaced with a new one.

Equipment diagnostics can be performed using special utilities. For example, “Windows Memory Diagnostic” allows you to identify problems with RAM.

The application writes a boot disk image. This ISO must be cut into a CD and booted into the PC from it. The program will carry out testing in cyclic mode.

BSoD or Blue Screen of Death in Windows can appear for various reasons. Starting from a failure in a separate program, ending with the breakdown of important equipment. If you've seen BSoD only once, it's too early to sound the alarm. But if the failure is regular, it means there is some problem with the computer. And you need to pay attention to the information that is shown in the error.

You were quietly working at your computer and saw the “Blue Screen of Death” in Windows 7. What to do in this case? There is no need to immediately restart your PC. Look at the error code. From it you will understand what is “broken.” And you can eliminate the cause of the failure.

When the BSoD appears, pay attention to the sections:

"The problem seems to be caused." The file that caused the failure is indicated there;
Below is the name of the error;
"Technical Information". Technical information. The error number must be written after the word “STOP”. For example, "0x0000007E" or "0xC0000135";
Next comes the driver name and error address.

Reasons for the error

Remember what happened before the Blue Screen of Death occurred. This way you can figure out what to do about it. For example, you connected a new device, installed a program, updated the system, or downloaded unlicensed drivers for Windows. If it was after this that problems began, then you have found the culprit. You can also determine the cause by looking at the error codes.

Here's what causes the crash:

Hardware faults. The hard drive, RAM, network card, video adapter may be damaged;

The problem may be caused by a faulty hard drive.

An incompatible device or equipment is connected. Let's say you decide to install new RAM cards or attach an external hard drive. And after that, Windows began to crash into BSoD;
Software conflict, in particular drivers;
BIOS failures or bad firmware;
Overheat;
Updating Windows or individual services. Along with this, you can download a huge number of errors. Even licensed programs are not immune from them. If BSoD appears after a system update, simply roll back the system. And wait until the update is fixed and optimized;
Contact between wires and internal equipment. For example, the cable got caught in the cooler blades;
, which damaged important files;

User actions. Someone tried to "overclock" the computer. Or deleted system data.

Error codes

To understand how to get rid of the problem, you need to look at the error codes. Blue Screen of Death provides the information you need. But the list of such numbers is huge. After all, anything can break. And it is not clear what to do in this case. Here are the most common failures:

“0x0000000X”, where “X” (“X”) are numbers from 1 to 5. Relevant for Windows Server 2003 and Win XP with SP. Appears when installing some antiviruses. To fix everything, download the “KB887742” update from the Update Center or from the official Microsoft website;
“0x0000000A” and “0x0000000X”, where “X” is equal to numbers from 6 to 9. The driver is damaged. Or there are incompatible programs/hardware;
“0x0000000X”, where “X” can be a number from 13 to 19. The codes mean that there is no communication with the memory board. Or the connection to the hard drive on which the swap partition is located is lost;
“0x0000001F” and “0x0000000X”, where “X” are numbers from 20 to 23. Error when reading/writing information. Appears in FAT file systems. The cause may be a broken hard drive or severe data fragmentation. Blue Screen of Death with this code also occurs due to incompatible antiviruses and firewalls;
"0x00000024". The same thing, but for the NTFS file system;
“0x0000000X”, where “X” are numbers from 28 to 35. Problem with drivers or RAM;
"0x0000000B", "0x0000000C", "0x0000000D". Associated with software failures for the Sound Blaster Live sound card;
"0x00000051". Occurs when the system cannot read a registry element. This happens when the system or equipment is damaged;
"0x00000057". There is something wrong with the network card;

Death screen example

"0x00000069". Incorrect system installation or incorrect configuration;
"0x00000073". Part of the registry is damaged. Or there is not enough free memory;
"0x0000007E". May appear when updating Windows. For some reason the update caused a failure. To eliminate it, you need to roll back the system;
"0x0000008E". RAM failure. Or the RAM modules are incompatible with each other;
"0x000000FE". Critical failure in the USB controller;
"0x00000104". Problem with the video adapter driver or BIOS firmware;
"0x1000007E", "0x1000008E" or "0xC000009A". The Windows system kernel does not have enough resources for stable operation. Free up RAM and local memory;
"0x80070570". The system is not installed correctly. The problem may be in the installer itself;
"0xC0000135" and "0xC0000218". Important dynamic libraries are damaged or missing. BSoD shows which object is unavailable;
"0xC0000221." Problem with driver or library;
"0xDEADDEAD". The user himself initiated an emergency stop of the system.

The list is quite long. It has hundreds of different rooms. You can enter the failure code in the search engine to find out detailed information. Or look it up on the website “bsodstop.ru” (tab “BSoD: description of errors”). There are also instructions that describe what to do in each situation.

If the same failures occur with different objects (the codes are the same, but the file names are not), most likely the problem is not in the system, but in the hard drive. Back up your important data as soon as possible. If they end up in a damaged sector, it will be difficult to restore them.

View the code if the system reboots

How can I find out the failure number if the computer restarts when a BSoD appears? And you simply don’t have time to read the message.

Blue screen codes can be viewed in dumps. They are located in the Windows\Minidump system directory. To open these files, you need the BlueScreenView program. Find it on the Internet, install it and open it. It will scan the dumps and display a list of them. Files that contain information about the failure will be marked in red.

How to fix the error

Equipment broke down

If the equipment breaks down, it is unlikely to be repaired at home. But sometimes it’s enough to turn it off and on again. Let's say the error codes make it clear that there is no access to RAM. Here's what to do:

Turn off the computer's power. Don't just press the "Off" button, but remove the plug from the socket;
Open the cover of the system unit;
Find the RAM boards there;

Carefully remove them from the nest. You need to pull back the latch that holds them;
Push them back in;
Turn on your computer and check if everything works.

The same can be done with a hard drive, a video adapter, and a sound card. But if you are unfamiliar with the internal workings of a computer, it is better to leave it to the professionals. You should not remove all the parts from the system unit one by one.

If it doesn’t help, it means the equipment has become unusable. It needs to be changed.

Disabling external devices

Very often, BSoD appears when hard drives or other external devices are connected to the computer. How to fix the Blue Screen of Death in this case? Turn off the equipment. Try inserting it into a different port. See how it appears in Device Manager. Check to see if there is an exclamation mark next to the model name. Update your drivers.

Perhaps the problem is not with the computer, but with the port controller. If it is faulty, it must be turned off.

Problems with the file system or hard drive

Run scan and repair of the system disk. For this:

Right-click on it;
Item “Properties”;

Go to “Properties”

“Service” tab;
“Check” button;

Click on “Run check”

Check all the boxes. In particular, you need the “Repair bad sectors” option;

Check the box next to “Repair bad sectors”

"Start" button;
The service will warn you that it will start checking the next time the system starts;
Restart your computer;
It will begin disk recovery. This may take a long time. Don't interrupt the process.

Software glitch

Here's how to remove the Blue Screen of Death if the problem is in the system itself or programs installed on it:

Uninstall everything you installed immediately before the crash;
If it doesn't help, make a backup;
Go to Start - Programs - Accessories - System Tools;
Press " ";

In the window that opens, check “Select a restore point”;
If necessary, check the box “Show all restore points”;
They show the time when the backup was made and what happened (installation, deletion, update);

Restore points

Select a suitable point and confirm;
Do not turn off your computer until the recovery is complete.

The system will roll back. It will return to the state it was in before the errors appeared.

Other options

Scan the system with a good antivirus;
Clean the hard drive from debris. Remove unnecessary files. But don't touch system data. You can use the built-in Windows services (Start - Programs - Accessories - System Tools - Disk Cleanup) or install programs for this: for example, CCleaner;

CCleaner program

It makes sense to fix registry errors. But you shouldn't do it manually. Use Registry Fix, Registry Boot and the like;
If you have an installation disk with the system, try reinstalling it or restoring damaged files;
Update all drivers. Download the latest updates.

If a Blue Screen appears when you turn it on

If the Blue Screen of Death appears immediately after turning on the computer, you will not be able to log into the system. And it will be difficult to fix anything. Therefore, you need to start the PC from a boot disk or drive. If you don't have one, use the Windows installation CD. A free program from DrWeb - “Live Disk” is also suitable. It can be downloaded from freedrweb.com:

When you start the PC (on the very first “frame”), a key will be indicated that must be pressed to open the settings (“PRESS TO ENTER SETUP”). This is usually F1, F2, F5 or Del;
Click on it. The BIOS options will open. In them, all control is tied to the keyboard;
Go to the “Boot” tab;
“Boot Device Priority” item;
There will be a loading order. Place first the device from which you plan to download data (disk or drive);
Open the “Save” section, select the “Save and reset” option;
Now the computer will start from the external media (don't forget to insert it);
If this is a boot disk or CD with Win distributions, try reinstalling them;
Live Disk also has tools for resuscitating the system;
After recovery, change the boot order again to start from the hard drive.

This will work if the problem is due to a software glitch. But it will not help in case of equipment failure

You need to take care of your system and computer, even if there are no problems. Regularly check the disk for errors, remove unnecessary junk from it, and clean the registry. Don't try to improve your PC's performance if you don't know how to do it. If you take precautions and monitor the state of the system, the Blue Screen of Death is unlikely to bother you.

You can handle some problems yourself. But if BSoD appears due to hardware failure, it will have to be replaced.

Many users get scared when they see a blue screen on their monitor because they have heard a lot about it, but do not always understand what it is. First, you should understand the terminology, since a blue screen in Windows can appear for various reasons.

So, when loading the computer, if you press the Del button, the BIOS panel (menu on a blue background) may appear, intended for setting up the system; in order to remove it, just press the Escape key. Also, during boot, a blue screen with changing percentages may appear, which means that the system is being checked for errors, most often it occurs due to improper shutdown of the PC. Actually, these cases do not pose a danger and there is no point in discussing them further.

Now, it’s worth mentioning separately about the blue screen, which appears due to errors, but not critical ones. So, when the PC boots, a notification may appear on a blue background indicating that a device is not connected. You should read the message carefully to determine what the problem is. Most often it appears in cases where the wired keyboard is disconnected from the system unit or its plug is simply not inserted tightly enough into the socket.

In such a situation, we simply check the reliability of the connection - if the plug is pulled out or inserted loosely, return it to its place and reboot the PC. If you check and find that the plug is fine, try a different keyboard and reboot again. Well, now let’s move on to that very “Blue Screen of Death” or BSOD. If the computer restarts automatically after the Blue Screen of Death appears, this is not very good, since it does not allow you to analyze the error.

In this regard, you must first disable automatic reboot. This is easy to do through the menu - in the “My Computer” context menu, select the “Properties/Advanced/Boot and Recovery/Settings” tab and uncheck “Restart automatically”. Now, after the Blue Screen of Death occurs, we will receive the necessary information that will allow us to troubleshoot problems causing a critical error.

If the system does not reboot automatically after a BSOD occurs, do not panic. The first thing you need to do is read the message on the screen, at the very bottom there will be a “Technical Information” section, which will indicate the reason for stopping work. The error is indicated by approximately the following number: 0x000000xxx; you need to rewrite this line on a piece of paper.

That's it, now we just restart the computer using the Reset key, or, as a last resort, disconnect it from the power supply (however, this should only be done if other methods have not worked). Since most often the Blue Screen of Death appears as a result of incorrect installation of updates or conflicts in software, we should find out what specific software caused the error. This is why we wrote down the error number earlier.

We enter this number into the search and read what experts can advise. Also, in some cases, a more detailed analysis of the error that has occurred may be required; there is a special program for this - BlueScreenView. After launching it, you will be able to get more detailed information about which driver caused the Blue Screen of Death to appear. We again enter all the information received into the search and determine what needs to be done to troubleshoot the problem.

Most likely, you have noticed more than once that when your computer crashes, the next boot appears. blue screen, and there are a lot of incomprehensible English words on it.

Has this ever happened? I'm sure so!

When newbies see this state of their computer, they usually get scared. But things are not always so scary. In this article, we will look at two types of blue screens and understand the situation, why they appear and how they can be dangerous.

First, let's look at the appearance of these blue screens. As I already said, there are two main ones that may appear when working at a computer.

Blue screen when checking disk:

If you experience such a blue screen, then you don’t need to worry too much. It appears most often when the computer is turned off incorrectly, when, for example, we turned it off without “ Start - Shut down computer", and from the outlet or during power outages.

There's nothing wrong with this. After the next boot of the computer, a special program is launched to check disks. It is built into Windows, called Chkdsk, and starts automatically after computer failures, an example of which we looked at just above.

What is he doing Chkdsk program?

She checks the hard drive for errors and corrects them if they exist, and they could have arisen as a result of a computer failure.

The disk checking procedure occurs in five stages, at each stage we can see progress as a percentage.

If you get a blue disk check screen, then it’s better to just wait until the program Chkdsk will check disks for errors and if they are, it will fix it, although you can interrupt this procedure if you press the Esc key immediately after such a screen appears.

If you experience such a blue screen rarely, then I see no reason to worry, but if it occurs frequently, I would recommend that you definitely make a backup copy of your important data, try it, and, as a last resort, change the hard drive.

Now let's move on to the second blue screen.

They call it the “blue screen of death”:

Blue screen of death Most often it appears suddenly when working at a computer and indicates that there is some kind of system error that Windows cannot fix itself. To avoid more serious problems, Windows shuts itself down and a blue screen of death appears. In this case, we can only restart the computer by pressing the Reset button on the system unit.

In some cases, a few seconds after the blue screen appears, it may reboot itself. When such a screen appears, all the data that was not currently saved: Word documents, text in Notepad, etc. unfortunately they will be lost.

Whenever blue screen of death The system tells us the error code that caused it so that we can try to fix the problem ourselves. But it is unlikely that we will be able to solve this problem ourselves, especially if we are new to these matters, since it is difficult even for an advanced user.

It is worth saying that when such a blue screen occurs, the system writes an error code to a special system log and creates a special file, and places all the data in it, which describes the problem in detail. This may be necessary for a specialist who will solve the problem.

Let's look at the most common reasons, Why does the blue screen of death occur?. This could be due to drivers. For example, when some others are installed instead of the native ones and they are not compatible with the operating system or our equipment. The cause may also be overheating of components or incorrect operation of programs.

Here we will not touch on all the details of the analysis of various error codes that are caused by the Blue Screen of Death, because this is a very large topic and not at all for novice computer users.

But if you still decide to figure out on your own why you are getting such a blue screen, then you need write down the error code the next time the blue screen of death appears, and start searching on the Internet.

If you have encountered this error, then I am sure that someone else has already encountered it. Read on the Internet what people write on forums, what they recommend, which can cause a blue screen with an error like yours.

If you do not have time to write down the error code due to the fact that the computer immediately reboots, then you need to make sure that it does not do this.

To do this, we right-click on the Mock Computer icon and select Properties from the list that appears.

In the window that opens, go to the Advanced tab, in the section click the Options button.

In the window that opens, uncheck the box next to the item Perform automatic reboot, make sure that the remaining parameters are set as in the picture and then click OK.

Now our computer will not reboot if it crashes and the blue screen of death appears. We need to write out everything that is indicated on the blue screen in the Technical Information section.

This is the most important data for figuring out the problem.

In addition to the fact that we can see this error on a blue screen, it is also recorded in a memory dump. This file with the dmp extension is stored in the folder by default:

C:\WINDOWS\Minidump.

To find out and eliminate the cause of the blue screen of death, this data is usually enough.

This concludes this article! Finally, I want to tell you that it will be very difficult for a beginner to understand such problems. But if you are confident in yourself, then you will succeed! On the Internet you will find a lot of information on any of your mistakes.

It may even be enough to solve your problem by simply reinstalling an incompatible driver, solving the problem of video card overheating, and so on.
