What to do when a blue screen appears or the computer automatically restarts. Most Common Blue Screen of Death Error Codes Windows 7 Blue Death

Today we will tell you what the Windows 7 blue screen of death is, what to do when it appears. We often see this phenomenon when the computer suddenly decides to randomly reboot. Windows 7 blue screen of death gives error codes along with a lot of obscure inscriptions. Knowing the meaning of the main codes will help eliminate the problem with the greatest efficiency. If we see a blue screen, this means that the operating system cannot correct the situation on its own. The appearance of the screen ends with a reboot, and all unsaved data is often lost. The main reasons for this phenomenon are: software error, problems with PC hardware elements.

Causes of BSOD - Screen of Death

The blue screen of death in Windows 7 occurs due to problems in individual devices of the computer system or errors in the drivers responsible for supporting these devices. BSOD in some cases occurs due to a failure in the kernel of the operating system, it is commonly called low-level software.

Using the operating system to determine the causes of the failure is not easy, but the BlueScreenView program will help us. This application scans error data files on its own and shows more detailed information about crashes.

The classic Event Viewer theoretically allows you to get similar information, but in this case it will be displayed along with information from the system log and messages about application crashes. BlueScreenView receives information about all the screens of death that have occurred in the system.

Here you can see a lot of useful information about the crash, among others:

• The driver that caused the error.
• Description of the error.
• Error code.
• The time and date the error occurred.

Let's name the main causes of the "blue screen":

• Most often, the problem lies in the failure of the driver of one of the devices in the computer system.
• Failure of a PC component, such as, for example, a video card or RAM.
• Incorrect overclocking of RAM or processor.
• misconfigured.
• Incompatible hardware, conflict between individual PC components.
• The computer is overheating.
• There are viruses in the system.

Advanced users and developers can use a more sophisticated tool from Microsoft called WinDbg.

Error codes

0x00000001

This code may appear if there are difficulties with the Compositebus.sys driver. When a portable or multimedia device is first connected to the PC, it installs the driver and resets the USB. It is the simultaneous access to Compositebus.sys that causes the error. If you try to install a third-party driver, you may experience a similar failure.

0x00000002

The device queue was not busy. The problem lies in the drivers or hardware. To fix the situation, you need to update the drivers. The computer also needs to be scanned for viruses. The registry needs to be cleaned up. A hard drive check for errors will also be useful. If this does not help, update the operating system to the latest version.

0x00000003

The error is also caused by or hardware environments. We are already familiar with the correction algorithm: we check the hard drive for failures, clean the registry, look for viruses, eliminate them, update drivers. If all this turned out to be useless, we also download the current version of the Windows operating system to our computer.

0x00000004

This code indicates an exceptional invalid situation with data access. The cause of the failure may be the PC hardware or device drivers. The recipe is already familiar to us: from everything superfluous, we eliminate viruses, we update driver versions. If this does not help, you will have to upgrade to a more modern operating system.

0x00000005

This failure is due to an encoding error in the Http.sys element. The operating system will need to be updated. so that the position does not repeat itself. This error occurs when the driver calls the KeAttachProcess function, and if the thread is busy with another process, a problem occurs. Using the KeStackAttachProcess function can be more efficient in this position.

0x00000006

This error is also related to KeAttachProcess . Moving to the KeStackAttachProcess function will also help here. Among other possible causes of this failure: a breakdown in the power supply, memory failure, overheating. It is necessary to check the health of the power supply, test the hard drive and make sure that there are no viruses in the system. If this does not help, update the operating system.

The Windows 7 blue screen of death, also known as BSOD (blue screen of dearh), appears when a critical error occurs in the operating system, due to which it is impossible to continue using the computer. Usually, such an error occurs due to the fault of the system drivers, but this does not always happen. It is worth noting that despite its formidable appearance, often the error is solved quite simply, which many users do not know about. Sometimes, it even resolves itself after a system reboot. Therefore, in this article, I will tell you what the Blue Screen of Death error is, when it occurs and how you can overcome it.

It is noteworthy that every operating system has this kind of error, for example, in Linux it is akin to the "Kernel Panic" error.

The Windows 7 operating system provides many different tools for dealing with error problems. For example, if you noticed that when an error occurs in individual programs, the system itself continues to run further, showing you only a small window with text.

However, Windows 7 is essentially the same set of programs. Internal mechanisms allow you to cope with a number of your own errors, but there are also those after which the system simply cannot continue its execution. These errors are unresolvable and the only thing that the system can do in this case is to warn the user about them, and then perform an emergency restart of the computer.

Since errors can be related to the video card, they are displayed in the simplest form, namely in the form of white or yellow text on a blue background, which fully describes the situation in which a critical system failure occurred. Actually, because of the background and fatality of the error, it received the name "Blue Screen of Death", which has become the basis of many existing jokes about Windows 7.

For most users, only two fragments of the entire typing are important, they are shown in the figure below:

As you can see, the first fragment is an inscription with uppercase letters and an underscore separator, and the second fragment is a description of files and codes. It is them that you need to write down or remember, and then look for their decryption on the Internet or on the Microsoft website.

Possible causes of the "Windows 7 Blue Screen of Death" error

Before trying to solve a problem, it is necessary to understand its source. There can be many, but the most basic ones are:

1. Problems with drivers. Unlike conventional programs, not everything is simple with drivers. Their errors can be critical for the operating system and therefore they cannot just be taken and restarted. For example, one of the common errors is a problem with network card drivers. In such cases, a simple reinstallation of the drivers is usually sufficient.

2. Lack of free space on the system drive. The operating system, during its execution, like some programs, creates temporary files on the system disk, so if there is no disk space at a critical moment, the system may display the Windows 7 Blue Screen of Death. This problem is solved by simply cleaning the system disk.

3. Another mistake is damage to important system files. In this case, you need to restore Windows 7.

4. Registry errors. These kinds of errors are very rare, but they do happen. In this case, you need to look for a solution on the Internet using the text from the blue screen of death.

5. Equipment failure. Errors can occur not only because of programs, and this is just as important to consider. For example, static on the motherboard can cause the death screen to appear. Or the usual overheating of the computer. At home, it is not always possible to cope with such errors. For example, with cooling, you can solve the problem yourself, but with static, only if you have the tools and the appropriate skills.

In most cases, errors occur due to some changes in the system configuration, for example, reinstalling drivers or installing specific programs, so loading Windows 7 with Last Known Good Configuration can solve the problem (sometimes just rebooting is enough). Nevertheless, I advise you to look on the Internet for the true cause of the error after loading the system. Coming back, here is an instruction on how to load the latest configuration:

1. Restart your computer and wait until after the first information screen, the screen turns black.

2. At this moment, press the F8 key to pop up the menu as shown in the figure above.

3. Within 30 seconds, select "Run with Last Known Good Configurations" among the items and press the enter button.

If the problem is not resolved, then you need to try to start the system in safe mode, for this, at step 3, you must select the appropriate item. In other cases, it is necessary to look for a decryption of the error on the Internet and the appropriate way to solve it. However, it is also useful to know a few things about diagnostics.

The problem with the Windows 7 blue screen of death is not only the error itself, but also the fact that by default, this error is displayed for only a few seconds. This is done so that the abandoned computer, due to an accidental failure, reboots without the user's help and "possibly" continues to function (if the error disappears after the reboot). Be that as it may, this is quite inconvenient for diagnostics, but this feature can be turned off and here's how it's done:

Many of you have probably already heard from friends and acquaintances more than once about such a concept as Windows 7 blue screen of death, which appeared on their computer, it is also called BSOD ( Blue Screen of Death).

With the appearance of a blue screen, Windows warns us that, and it is advisable to eliminate them in a timely manner. The death screen shows error codes that can be used to understand why it is happening, and from this to conclude which component of the computer is failing or a software problem.

If your computer with Windows 7 started to issue a BSOD, then you and I need to understand why it appears, and for this you need to write down the error code in your notebook or take a picture of the monitor screen, and then, having filled in the error data, in the search bar or, we are looking for what it means or we read the article in full, in it you will find the codes of the most common errors due to which the blue screen of death appears. But first, we will carry out preparatory work with you.

Configuring Windows 7 to diagnose BSOD

In order for us to have time to write down or photograph the blue screen error code, we need to do some system settings.

It is necessary to turn off the restart of the PC when an error occurs, as well as enable the recording of debugging information in a memory dump.

• Memory dump- the contents of RAM at a certain point in time, let's say a special image.
• Small memory dump - part of the memory that is written to the hard drive during crashes, leaving only the most important information there.

In order to go to the system settings, open "Start", select "Computer", right-click on it and select "Properties"

A new window will open, in which we select the "Advanced" tab and click the "Options" button in the "Download and Recovery" item

Next, we look at the section "Write debugging information" there you need to select "Small memory dump 256 KB"

Now your computer is set up, the next time it crashes, it will not restart, and you can safely write down the error code or take a picture of it.

Blue Screen of Death, Windows 7 error codes

Let's now look at the most common error codes.

• KMODE EXCEPTION NOT HANDLED - the computer gives such an error if there is a problem with the hardware (for example, any component of the computer has failed) or a problem with the drivers.
• NTFS FILE SYSTEM - problems with the hard disk file system, this problem can occur in several cases:

* the presence of viruses in the boot area of ​​the hard drive

* damage to the structure of the file system.

• INACCESSIBLE BOOT DEVICE - when this error occurs, the Windows operating system says that it could not access the boot partition of the disk. There can be many problems causing this error. For example, a problem in the PC hardware: the hard drive is damaged, the controller is faulty, individual computer components are faulty, or a software problem: viruses or file system errors.
• IRQL NOT LESS OR EQUAL - this error may appear when there is a problem with drivers or some Windows system service

• PAGE FAULT IN NONPAGED AREA - a blue screen of death with this code means that the data that the system is looking for is not in memory, respectively, when the operating system accesses, for example, data in the paging file, but there is nothing there, such an error will appear. The error often appears due to problems with RAM, errors in Windows system services, or due to a corrupted file system.

• KERNEL DATA INPAGE ERROR - the operating system is unable to read data from memory. This error can be caused by bad RAM, hard drive problems due to unreadable sectors, or a problem with the HDD controller.
• KERNEL STACK INPAGE ERROR - The OS was unable to read the paging file and write data to the hard drive. The main causes of this error: a problem with RAM or hard drive.
• UNEXPECTED KERNEL MODE TRAP is an error that appears at the kernel level of the system. The reasons that caused it can be both hardware and software.
• STATUS SYSTEM PROCESS TERMINATED - an error caused by a software failure, problems with system services, drivers or applications
• DATA BUS ERROR - a blue screen appears when there is a RAM failure or a video adapter failure.

Windows 7 blue screen of death, what to do?

After we have determined what kind of error we have, we need to establish the reason for which our computer began to crash. To do this, you need to remember what recent changes took place on your computer. You may have installed a new program or updated drivers for some device. To eliminate the human factor, you need to remove the latest installed programs, as well as roll back the drivers to previous versions. If errors began to appear after installing new hardware in the system unit, then you need to turn it off and observe the operation of the computer.

In order to resolve the error caused by a software failure, you need to try the following steps.

• Roll back installed new drivers to the previous version;
• Start Windows with Last Known Good Configuration;
• Perform a system restore using the standard Windows function.

I advise you to check the amount of remaining free space on the system partition of the hard disk, as a small amount of memory can cause system crashes. Do not forget to check your computer for viruses, for this you can use the free Dr.Web Cureit utility or the KVRT utility from Kaspersky Lab. If the blue screen of death continues to appear, I recommend installing the latest Windows 7 service pack.

Reset the BIOS settings to default, incorrect overclocking of computer components may have been performed, due to which the hardware works at incorrect settings that differ from the factory ones, thereby malfunctioning. To reset the settings, you need to go into the BIOS, press the F5 key and to save the settings, F10. The computer should restart and apply the new settings.

If you recently climbed into the inside of the system unit to remove dust, then it is possible that some connector was connected incorrectly or not tightly. To eliminate this kind of problems, pull the RAM out of the connectors and insert it back until it clicks. Also check the connection of all cables, remove other components installed in the system unit and reconnect.

In order to rule out failures of RAM and hard drive, perform a stress test for them, for example, with the Aida program. If the components fail this test, replace them with known-good components and check the operation of the computer.

That's all for me, now you know what to do with the blue screen of death in Windows 7.

A critical error in Windows that causes the Blue Screen of Death to appear is accompanied by a system freeze and an abrupt end of the session, followed by a reboot. As a rule, because of it, unsaved data for the session is lost. Also, often the appearance of a critical error with a “blue screen” indicates serious malfunctions in the operating system and can lead to even more unpleasant consequences.

Causes

Before trying to deal with an error, you need to identify its causes and try to find an appropriate way to solve it. In total, the reasons can be divided into two large general groups - hardware and software. The first arise in case of problems with the internal components of the computer. The second with the software part of the computer. The most common hardware problems are:

• You have installed additional hardware that is incompatible with what is already installed. For example, they added RAM sticks that are incompatible with the motherboard or another stick;
• Failure of certain computer components, such as a hard drive or RAM strip. In such cases, the operating system may not boot at all;
• You have incorrectly overclocked a video card, processor, or some other component.

Causes with a software component can be divided into the following categories:

• Driver conflict and/or incompatibility with current hardware and software;
• Penetration of virus software and its vigorous activity;
• Incorrectly installed updates of the operating system or programs important for its operation;
• Failures in the operation of important system applications and services.

Option 1: Software Conflict

If you recently installed a program, then there is a chance that this program conflicts with the operating system. It is also possible that some program on the computer has been updated, but the update packages conflict with the operating system or other programs. Usually this concerns important system programs.

Provided that suspicions fall on a recently installed program, it must be removed. You can do this in the following way:

If you can’t determine which program is causing the error, or you think that it’s not the program itself that is to blame, but its updates, then you will have to use the system restore option. From the interface of the operating system itself, this can be done as follows (relevant only if there is "Restore points"):

1. Run "Control Panel".
2. Expand the element there "Recovery". If you can't find it, put it in front of "View" parameter "Large Icons".




3. Here you will need to click on the button "Starting System Restore".




4. If your computer does not have "Restore points" then you will get an error message. You will have to use the installation image of the operating system from the flash drive. If everything is fine, then a window will appear, where there will be a brief description of the system restore function. Click "Further".
5. From the list provided, select the desired "Restore point". You need to choose the one that was created at a time when the computer was working fine.




6. Click "Further".




7. The procedure will start. Wait for it to complete and don't touch anything. The process usually takes about an hour. Your personal data will not be affected.

If you do not have a "Restore Point" or the system does not boot, then you will have to restore it using a flash drive with a recorded system image. It is important that it be of the same version and bitness as your operating system:

Option 2: Infection with viruses

There is some possibility that the "blue screen of death" appears due to the fact that the computer was infected with viruses. In this case, you will have to perform a virus removal. Unfortunately, in Windows 7, the standard Defender antivirus is not as high quality as it is assembled in Windows 8 and 10, so it will not be used in this article.

You will have to download and install some kind of antivirus if you don't have one. In this article, we will look at how to scan your computer for viruses and remove them using Kaspersky Free. This antivirus is a stripped-down version of paid solutions from Kaspersky, but is distributed completely free of charge. Its capabilities are enough to detect even the newest viruses:

Option 3: Not enough free space on Drive C

If there is too little space on the main hard disk volume, then the computer may often slow down and give various errors, including the “blue screen of death”. As a rule, in such cases, it is sufficient to simply clean up Drive C. Microsoft recommends that a minimum of 100 megabytes of free memory be left on the drive. This is enough for the computer to function more or less normally and without failures. However, practice shows that for better computer performance, you need about 10-15% of free space from the total volume size.

Let's look at how you can quickly clean your hard drive from various garbage using CCleaner. User data will not be affected.

If the cleaning did not free up enough disk space, then you can also try to fix possible errors in the registry using the CCleaner program. This can also free up some space:

You can additionally free up space on Disk C by deleting and moving programs to another volume. With CCleaner, you can uninstall this or that program:

Option 4: Install system updates

It is possible that all problems are due to incorrectly installed or not installed updates at all. Some builds of Windows 7 are not always stable, so they are recommended to be updated to get rid of most problems, as updates contain fixes. However, if you have a pirated copy of Windows installed, then it is better to refrain from updating, as you risk exacerbating the situation.

The Windows 7 upgrade process is as follows:

Option 5: Update Drivers

Very often, the appearance of a blue screen of death is associated with incorrectly installed and / or not installed drivers at all. In this case, you need to reinstall the "problem" drivers. However, it is very difficult to find out which component caused the error, especially if there are several of them, so it is recommended to use programs that automate the process.

The best solution in this case is DriverPack Solution. This program does not require installation on your computer. It is completely free, and the search and installation of drivers occurs automatically:

1. Go to the official website of the Driver Pack developer. Click on the button "Install all necessary drivers". After that, an archive with an EXE file will be downloaded to your computer, which you will need to run.




2. If the program is launched for the first time, then it starts scanning the computer for missing drivers. It usually takes no more than a minute.




3. Driver Pack will prompt you to use the parameters automatically selected for your computer. To do this, use the button . However, in this case, DriverPack may install programs on the computer, the installation of which it considers justified. Usually this software is not really needed by the user.




4. If you do not want any additional software to be installed on your computer, but only the drivers you need at the moment, then use "Expert Mode", which is located at the bottom of the window.




5. Here, pay attention to the left side of the window. There you need to go over the tile with the icon of 4 squares.
6. Uncheck all applications that you currently do not need on your computer or have already been installed.




7. When you're done, go back using the wrench icon. There click on the button "Set up your computer automatically". In this case, only drivers that remain checked will be installed.




8. After clicking on the button, the program will create "Restore point", with which you can roll back driver updates if they are suddenly performed incorrectly.




9. Wait until your computer is set up and the correct drivers are installed. When it's over, you will need to click on "Further".




10. Restart your computer and check if the blue screen error is gone.

Option 6: System errors

The blue screen in Windows 7 can provoke all sorts of system errors. It is recommended that you write them down when prompted and look at the documentation for them on the Microsoft website. If you do not have the opportunity to view the error window, then you can view it in a special window that opens as follows:

You can look for a solution to this problem on the official Microsoft website, but remember that most system errors are resolved by running the operating system recovery process. The procedure was described in detail in the first scenario.

Option 7: Reset BIOS settings

Incorrect settings in the BIOS can cause a blue screen to appear when working in the operating system, but most often when it starts. In this case, it is recommended to reset the BIOS settings or try to change the setting that causes the blue screen.

Since you hardly know which particular parameter in the BIOS is configured incorrectly, that it causes a blue screen, the only option left is with a complete reset. It can be made from the interface of the operating system, but most likely it does not start because of the blue screen, so consider the universal option:

Option 8: Hardware problems

It is possible that the cause of the critical error and the blue screen was the incorrect connection of any important computer components to the motherboard. Most often this happens if suddenly some contact fell out of its socket. To do this, you will have to disassemble the computer / laptop case and check if everything is in order. Additionally, inspect cables and loops for physical defects.

If during the inspection it turns out that one of the elements is not connected tightly enough, then simply reconnect it. Provided that malfunctions were found on one or another element, this part will have to be taken for repair or replaced with a new one. This statement is relevant both for damaged cables / cables, and computer elements (hard drive, motherboard, etc.).

As you can see, there are a lot of reasons that can cause a blue screen of death in Windows 7, and each of them needs to be “fighted” in different ways. Within the framework of this article, all variants of the occurrence of a critical error were considered and recommendations were given for their elimination.

The seventh version of the Windows operating system from Microsoft, although considered one of the most stable, is also not immune from critical failures. One of the most unpleasant phenomena is the "blue screen of death" of Windows 7. Not every user knows what to do when it appears. Some believe that the problem will disappear on reboot (and with good reason). Others believe that a complete reinstall of Windows 7 will be required. But before deciding to fix the problem, you need to know its essence.

BSoD death screen: what is it?

So, let's say that the user has a blue screen of death. What to do? Windows 7, as well as any other system in this family, can offer several solutions to the problem, depending on what was the root cause.

But in some cases, in order to get rid of this scourge in the future, you cannot do without special utilities. We will dwell on them a little later, but for now let's see what it is from the point of view of the system itself.

Roughly speaking, BSoD is a kind of defensive reaction of Windows to a critical failure in the system when a memory dump is written. In other words, the system cannot neutralize the error in the work by its own means and because of this reports that such and such has happened. In each case, deciphering the "blue screens of death" of Windows 7 can say a lot. Typically, a message on the monitor begins with the word "STOP" followed by a fault code. What does this mean? Yes, only that at the moment some important process was stopped, vital for the functioning of the system as a whole. How to remove the "blue screen of death" of Windows 7, we will consider a little later, but for now let's dwell on the reasons for its appearance.

Causes of failures

When investigating possible problems, you need to clearly divide them into two broad categories: software failures (including the system itself) and physical problems with hardware (for example, when replacing a hard drive, video card, RAM, etc.).

In addition, in Windows 7, solving problems with such problems may also imply a moment related to the fact that there is simply not enough space on the hard drive, which is especially noticeable when automatic system updates are enabled.

Group classification

To date, there are two main groups of failures. Group "A" includes problems with updating or replacing hardware, updating drivers or the system itself, and damage to system components. Group "B" includes incompatible versions of the primary I / O system BIOS, driver mismatch for a specific device, driver conflicts, lack of space on the hard drive, breakdowns of the "iron" components of the computer system, overheating of the processor or power supply, power outages, malfunctions of the brackets RAM, problems with video cards, overclocking (overclocking) results, etc.

Windows 7 Blue Screen of Death Codes

As you can see, there can be quite a lot of reasons for errors and failures. In any case, when such a screen appears, first of all, you should pay attention to the description that is present at the bottom of the message. Separately, you can highlight the most common codes that are most common:

• 0x0000006B;
• 0x00000000 (0022);
• 0x0000007E;
• 0xC0000005;
• 0x80000003;
• 0x80000002;
• 0x804E518E;
• 0xFC938104;
• 0xFC937E04 etc.

Of course, the list is not limited to these codes only (you never know what situation may arise). However, the most common "blue screen of death (0x0000007E)" occurs, Windows 7 in this case gives a description indicating that some kind of exception was not handled.

But this is just a summary. To view a full description of an error or failure, it is better to use a small utility called Blue Screen View. It is this program that can give the key to understanding how to treat the "blue screen of death" of Windows 7. This can be done using the system's own means, which will be discussed further.

"Blue Screen of Death": what to do (Windows 7)? The first and easiest solution

In the case when the failure is short-term, for example, due to a sudden power outage and the transition to an uninterruptible power supply, you can use the usual reboot with a forced shutdown by long pressing the power button.

But if the “blue screen of death” appears again when loading Windows 7, this will already indicate serious damage. For a start, you can try to simply disable the recording of dumps and mini-dumps. This is done through the properties section, called from the right-click menu on the computer icon, where you need to go to the download and restore item through the advanced settings tab. In the options window, you need to disable automatic reboot and recording small dumps, and then perform a full system restart.

If after that the problem is not fixed, it is very likely that this is no longer a software failure, but physical damage to the hardware (most often the problem is in the hard drive and RAM).

Viruses

One of the reasons for the appearance of failures can be viruses and malicious codes purposefully affecting the system. They cause a lot of trouble, overwriting system components and replacing them with their own files, and can also cause a "blue screen of death". What to do? Windows 7 has no means in this case, apart from its own primitive tools in the form of a defender and a firewall.

In the simplest case, you should check the system with a regular anti-virus scanner, but, most likely, you will have to use more powerful programs. The best option would be the free disk utility Kaspersky Rescue Disk, which can perform its own loading even before the system starts and detect viruses that have penetrated deep into the RAM.

System component failures

If it is the system that is damaged, the recovery may not work. In this case, it is best to boot into Safe Made mode using the F8 key at startup, and then, if you have constant Internet access, perform an online recovery by using the command shown in the image below from a command prompt run as administrator.

The process will take 5-10 minutes, after which you should write the sfc / scannow command and wait for the verification verdict. In the event of a violation of the integrity of Windows 7, system files will be restored automatically.

Lack of hard drive space

Lack of space in the system partition can also lead to the “blue screen of death” of Windows 7. How to fix the situation? To do this, the system provides its own disk cleanup tool. It is advisable to use it, and not the modules of optimizer programs, since the latter do not interfere with the system part.

In Explorer, right-clicking on the drive or partition being checked opens the properties menu, in which you can see the cleanup button on the general settings tab. After clicking it in the window, select all the components to be removed and confirm your actions.

Incorrect installation of updates

Quite often, incorrectly installed or underloaded updates become the cause of BSoD. It makes no difference whether automatic updates are enabled, or whether the search for updates was done manually.

How to remove the "blue screen of death" Windows 7 in this case? You need to go to the appropriate section of the "Control Panel" and view the latest installed updates. They will have to be removed one by one, rebooting the system each time after uninstallation. Perhaps the reason is just in them. As a last resort, if you do not want to do such things manually, you can try to roll back the system to a previous state. But it is worth considering that with automatic installation enabled, updates will be integrated into the system again.

But in the first case, having found out which update failed, it can be excluded from the list during a manual search again.

Hard disk errors and damage

The most problematic situation is when the cause of the failure lies in the hard drive. In the simplest case, you will have to check it for errors.

For this, the checker tool from the properties menu is used, but in the settings, the lines for automatic error correction and fixing bad clusters are activated. The same procedure can be performed from the command console, where you need to write the line chkdsk / x / f / r.

If the damage to the hard drive is physical, nothing can be done, although some experts recommend using a special hard drive remagnetization program called HDD Regenerator. True, there are legitimate doubts about the fact that it is possible to restore a disk in this way (in the sense of using software tools). Nevertheless…

BIOS incompatibility

Another problem is outdated or incompatible BIOS firmware. The screen will be displayed immediately at startup. In this situation, there is nothing left but to turn to the manufacturer's resource on the Internet. As already clear, you need to download the firmware and install it.

Information about the BIOS version can be obtained in the system information section, which is called by the msinfo32 command from the Run console (Win + R).

Incorrectly installed drivers

But most often, the appearance of a deadly screen is influenced by drivers or conflicts between them (the most common problems occur with video cards). At the same time, if you turn to the "Device Manager" (the devmgmt.msc command in the "Run" console or the section of the same name in the "Control Panel"), it is not recommended to update the drivers.

It is best to remove the problematic driver and then install it from scratch. In some cases, this may not give a positive result. Therefore, you will have to completely remove the device. When restarting the system, it is advisable not to use the installation of the most suitable driver from its own database, but to install it, for example, from the Driver Pack Solution catalog or preload the required driver from the equipment manufacturer's website.

But to search for the driver itself, first in the same “Device Manager” for the problematic component, you need to find the VEN and DEV identifiers in the properties with a transition to the details tab, where the equipment ID display is selected from the drop-down list. For reliability, it is best to use the longest line in the description.

Damaged RAM

But suppose the blue screen of death reappears. What to do? Windows 7 seems to have exhausted its capabilities. Apparently, the problem is in the RAM.

You can find out the cause of the failure provided that the appropriate verification program is activated. The most powerful utility is Memtest86+. But there is also the flip side of the coin. On stationary PCs, it is quite easy to remove memory sticks one by one from the slots on the motherboard, reboot the system and look at its behavior. You can’t do this in laptops, so you have to contact a service center.

Problems with the remote control program

Finally, although infrequently, there is a problem with remote access programs. Specifically, this is a Win32k.sys file error. The way out of this situation can be the usual removal of a failed application. Only it is better to uninstall not by means of the system, but to use programs like iObit Uninstaller for this, which can not only remove the main program files, but also completely clean the system from residual files, folders, and even system registry entries.

Instead of an afterword

As can be seen from all of the above, there can be quite a few reasons for the appearance of failures in the form of BSoD. And it will not always be appropriate to reinstall Windows 7. Finally, it remains to give advice to most users who believe that such a screen means a “rally” of the system. There is nothing too critical about this. In most cases, a simple reboot or reinstallation of drivers helps, of course, provided that there is no physical damage to the hardware.
