A blue screen popped up. Damaged RAM. Analysis by dumps

Good afternoon.

Although, he’s probably not that kind, since you’re reading this article... Actually, blue screen death is not a pleasant pleasure, especially if you spent two hours creating some kind of document, but autosave was turned off and you didn’t have time to save anything... Here you can turn gray if it’s a coursework and you have to hand it in the next day. In this article I want to talk about step-by-step restoration of your computer if you are tormented by a blue screen with enviable regularity...

And so, let's go...

You probably need to start with the fact that if you see a “blue screen”, this means Windows has completed its work with a critical error, i.e. There was a very serious failure. Sometimes, it is quite difficult to get rid of it, and only drivers help. But first, let's try to do without it!

Eliminating the blue screen of death

1) Setting up your computer so it doesn’t reboot during a blue screen.

By default, Windows OS, after a blue screen appears, goes to reboot automatically without asking you. There is not always enough time to record an error. Therefore, the first thing we will do is to prevent Windows from rebooting automatically. Below we will show how to do this in Windows 7, 8.

Open the computer control panel and go to the “ system and safety«.

Here we are interested boot and recovery options.

In the center of the window, under the “system failure” heading, there is an item “ execute automatic reboot ". Uncheck this box so that the system does not reboot and gives you the opportunity to take a photo or write down the error number on paper.

2) The error code is the key to solving the error

A blue screen of death has appeared in front of you (by the way, in English it is called BSOD). You need to write down the error code.

Where is he? The screenshot below shows the line that will help determine the cause. In my case, the error is like “0x0000004e”. I write it down on a piece of paper and go look for it...

I suggest using the site http://bsodstop.ru/- here are all the most common error codes. By the way, mine was found too. To solve it, they recommend that I identify the faulty driver and replace it. The wish, of course, is good, but there are no recommendations on how to do it (we'll look at it below)... This way you can find out the reason, or at least get very close to it.

3) How can I find out the driver that caused the blue screen?

In order to determine which driver caused the failure, you will need the BlueScreenView utility.

It's quite simple to use. After launch, it will automatically find and show errors that were recorded by the system and reflected in the dump.

Below is a screenshot of the program's operation. Errors when a blue screen occurred, date and time are shown at the top. Select the desired date and see not only the error code on the right, but also the name of the file that caused the error is shown at the bottom!

In this screenshot, the file “ati2dvag.dll” somehow did not suit Windows. Most likely you need to install newer or older drivers on the video card and the error will disappear by itself.

Similarly, step by step, you will be able to identify the error code and file that is causing the crash. And then you can try to replace the drivers on your own and return the system to its previous stable operation.

What to do if nothing helps?

1. The first thing we try to do when a blue screen appears is to press some keys on the keyboard (at least that’s what the computer itself recommends). 99% that nothing will work out for you and you will have to press the reset button. Well, if there is nothing else left, click...

4. If the computer displays a blue screen immediately at the moment of Windows boot, and not immediately after it (as in point 2) - then most likely they were damaged system files the OS itself. To restore, you can even use standard utilities system recovery by control points(by the way, in more detail -).

I hope at least one piece of advice from this article will help you...

While loading or working operating system Windows may experience an error or crash that results in a blue screen with white text.

Moreover, in this case, you can only reboot the computer, since other actions will be unavailable. It is for this reason that this very screen is called the “blue screen of death” (BSOD).

What it is

When a Blue Screen of Death appears, it means what happened crash operating system. The reason for such a failure can be very diverse. Similar problem can happen to anyone, so you need to know what to do if a BSOD appears.

There is no need to worry or fuss too much. It is recommended to reboot system unit, and all unsaved data will be lost.

Often, when you reboot, the problem disappears, but it is still useful to know the reason why the failure occurs. To do this, you need to analyze some line located on the blue screen of death, which contains the error check line and verification code errors to find information about them on the Internet.

System Setup

In order to be able to diagnose the problem and fix it if a critical failure occurs in the operating system, you should configure the operating system in a special way.

To do this you need:

• check what's in Windows settings memory dump saving enabled;
• Based on the required size of the memory dump file, you need to check whether it is enough for system disk free space for its location;
• disable rebooting the operating system after a BSOD appears.

Windows XP

To configure Windows operating system settingsXPnecessary:

• enable recording of debugging information, namely go to:

• specify how much debugging information should be written if a failure occurs.

WindowsVista/7

WindowsVista/7 settings are similar Windows settings XP.

Windows 8

In Windows, you can configure settings so that the operating system does not automatically reboot. In Windows 8, this requires:

Transcript of the mixing in Blue Screen of Death

Each critical error is accompanied by detailed description and an eight-digit error code. When you first encounter a BSOD, the information displayed on it seems to be a random sequence of characters, but in fact, the description and error code will help to a large extent identify why the failure occurred and what this error means.

At the top of the monitor is a description of the error, consisting of words cobbled together written in capital letters and separated by underscores.

Directly after the error description, some troubleshooting tips are displayed. They are followed by a section technical information with an eight-digit hexadecimal error code.

Depending on the nature of the error, the code is usually supplemented with four auxiliary values ​​enclosed in parentheses.

If the error that caused the BSOD directly depends on a file, its name is displayed in this section.

Reasons for appearance

There are many reasons why the Blue Screen of Death appears.

All reasons for the appearanceBSODin Windows can be broken down into three components:

• equipment;
• drivers;
• programs.

Video: Blue screen in Windows

Equipment

One of the most common reasons, which can cause BSOD, in this category are RAM problems. It needs to be tested.

Failures in the functioning of the data storage system are also common. In this case, it is worth diagnosing HDD and check if there is free space on it.

Less commonly, the cause of the blue screen of death is problems with the video adapter and processor. It is important to test this equipment using specialized utilities.

In addition to the main components of the computer, problems may arise with additional fees, expanding functionality system unit. You can find out the source of the problem by removing additional nodes and testing the computer for several days without them. If the computer is operating in normal mode without failures, it means the problem is solved.

You can also try connecting the board to a different slot motherboard. After testing all components separately, you should test the operation of the entire system under load. If it fails under load, the problem probably lies in the operation of the power supply. The way out is to replace the power supply with a more powerful one.

Drivers

There is an opinion that drivers are the source of 70% of BSOD cases. To cure the system, the driver must be reinstalled after removing it. If the problem is not solved, then you need to download the driver from the manufacturer’s website and install it.

There are situations when it is not possible to find fresh driver, in this case you can install an earlier version.

If replacing the driver does not help, then you should check the compatibility of the device with the operating system. If compatibility is not available, it is recommended to replace the hardware or reinstall the operating system.

BY

Problems encountered related to software, are solved similarly. You need to reinstall the existing one, or install the version downloaded from the developer’s website.

The probable cause of a critical error may be the simultaneous installation of two or more antivirus agents per operating system.

Memory dump analysis

To analyze critical memory dumps, you can use one of huge amount program, for example, DumpChk, Kanalyze, WinDbg.

Let's look at the example of WinDbg (part of Debugging Tools for Windows) how to perform analysis crash dumps memory.

The sequence of actions is as follows:

• download current version programs from the developer's website;
• install the program on your computer;
• run the program;
• go to the menu item “File –> Symbol File Path...”;
• In the “Symbol Search Path” window, click “Browse...”;
• in the window that appears, select the location of the Symbols directory. Then click “OK” twice, and then select the menu “File –> Open Crash Dump...”;
• in the “Open Crash Dump” window, select the path and click “Open”;
• in the “Workspace” window, set the “Don’taskagain” checkbox to “No”;
• The “Command Dump" window will appear with dump analysis;
• analyze the memory dump in detail;
• It is especially important to pay attention to the “Bugcheck Analysis” section, which displays the possible cause of the failure;
• to view complete information you need to click on the link “!analyze -v”;
• close the program;
• apply the obtained data to eliminate the cause of the crash.

Troubleshooting blue screen of death errors

The lion's share of blue screen of death errors is caused by corruption of some system files or missing or incompatible drivers.

WhenBSODyou need to do the following:

Error codes

To “treat your computer” faster and more effectively, you need to have an idea of ​​what error codes mean and how to fix the blue screen of death problem. Therefore, it is extremely important not to ignore the text that displays the BSOD. Most important information on the blue screen of death is hexadecimal code errors and their description.

The number of BSOD errors reaches several hundred. It is simply impossible to know or describe all error codes and how to eliminate them. It is much easier and more optimal to use specialized resources, which contain detailed information about errors and describe the sequence of actions to solve the problem in the most effective and safe way.

To do this, you just need to go to the appropriate resource, find the error with the required code, study information about it and restore the operating system in accordance with the recommendations received.

The most common errors:

• 0x00000001 – Internal error kernels;
• 0x0000000A – unavailable address memory;
• 0x0000001E – incorrect command processor;
• 0x00000020 – driver error;
• 0x0000002B – stack overflow;
• 0x00000051 – registry error.

In some cases, the operation of the Windows operating system may end with the appearance of a blue screen of death, which displays specific sequence characters.

The appearance of a BSOD indicates a critical error in the operation of the operating system. The method for resolving the failure depends on the system error code, which can be viewed at the bottom of the blue screen.

Good day, dear readers!

Hardly any of active users I haven’t encountered such a thing on my computer as a blue screen with a bunch of white text, which can only be gotten rid of by restarting the computer.

In this article I will tell you what it is, why it happens, and how to deal with it. The article turned out to be very long, but it covered all the points from the reasons for the appearance of the blue screen of death to their elimination.

Blue screens of death on different computers and operating systems (OS) look different. IN Lately they become no longer quite blue.

For example, here is a blue screen with the image sad smiley developers offer us new Windows 8, scheduled for release in 2012. This BSoD can be observed quite often when testing the capabilities of a new operating system. Perhaps this is one of the most positive, so to speak about BSoD, blue screens of death.

However, some have encountered the red screen of death in earlier versions Windows Vista, which served as blue. In the older days of Windows 1.0 and Windows 2.0, the screen was completely black! The blue screen began to be called starting in 1991, when this name was proposed by Erik Noyes, an employee of one of the Californian companies. Since then, the concept of “blue screen of death” has become generally accepted.

What is Blue Screen of Death

A concept that comes from in English and translated into our native language. Actually, as you already understand, BSoD and the “blue screen of death” are one and the same thing. The abbreviation BSoD stands for Blue Screen of Death or Blue Screen of Doom. Official name phenomena - Stop Error.

When you see a blue screen on your computer monitor, it indicates a critical system error. This method of informing the user about a failure is typical for Windows OS.

So what is BSoD? In Fig. 1, you can parse the CRITICAL_OBJECT_TERMINATION entry. This is a blue screen of death error with the code (technically correct - STOP code) 0x000000F4. A short notation is also used, discarding zeros after 0x - 0xF4. Further in the article, this particular recording will be used when there are no other numbers. Blue screen of death codes are an entry in hexadecimal system prefixed numbers 0x. This prefix is ​​used to recognize system services using language C.

Using STOP BSoD code the system identifies the error that occurred and makes an entry in the system log for subsequent analysis and prevention of the error in the future. Blue screen of death error 0xF4 indicates a failure that occurred due to an unexpected termination of a system-critical process or thread. We will talk more about the meaning of blue screen of death errors below.

More detailed information for advanced users is provided by BSoD, used in Windows XP/Vista/7, the most common today, as well as Windows Server 2003.

Rice. 2. Blue Screen of Death in Windows XP/2003/Vista/7 Using this BSoD, it is much easier for an advanced user to figure out what the problem is.

First, Microsoft notifies the user that the BSoD is caused by a shutdown to prevent the computer from crashing. The following is the system file SPCMDCON.SYS - the culprit, according to Windows, of an emergency shutdown. Below is the blue screen of death error PAGE_FAULT_IN_NONPAGED_AREA - indicating that the data contained in memory was not found. The following is a guide for further actions user in order to prevent a similar error from occurring in the future. Below is technical information: STOP code 0x50 and again the SPCMDCON.SYS file, this time with parameters.

Agree, this BSoD can lead to much more confusion inexperienced user than the one they offer Windows developers 8.

The most common blue screen of death codes

We list the most common blue screen of death errors. The following is short description the reasons why the blue screen of death is most likely to appear. However, to accurately diagnose the problem, you still need to refer to the error parameters and interpret them correctly using debugging programs.

0xA - IRQL_NOT_LESS_OR_EQUAL - incorrect address when accessing the device driver;
0x1E - KMODE_EXCEPTION_NOT_HANDLED - The kernel mode process is attempting to execute an invalid instruction;
0x24 - NTFS_FILE_SYSTEM - failure in file system NTFS;
0x2E - DATA_BUS_ERROR - parity error in RAM;
0xB4 - VIDEO_DRIVER_INIT_FAILURE - video driver initialization error;
0xB9 - CHIPSET_DETECTED_ERROR - the motherboard chipset is faulty;
0xC2- BAD_POOL_CALLER - memory allocation operation error;
0x4E - PFN_LIST_CORRUPT - driver input/output structure is damaged;
0x50 or 0x8E - PAGE_FAULT_IN_NONPAGED_AREA - data requested from memory is missing;
0x69 - IO1_INITIALIZATION_FAILED - system initialization failed;
0x77- KERNEL_STACK_INPAGE_ERROR - reading the requested kernel page is impossible;
0x79 - MISMATCHED_HAL - hardware incompatibility;
0x7A - KERNEL_DATA_INPAGE_ERROR - error reading into physical memory;
0x7B - INACCESSIBLE_BOOT_DEVICE - no access to the system disk partition;
0x7F - UNEXPECTED_KERNEL_MODE_TRAP - unexpected error operation in the kernel;
0xD1 - DRIVER_IRQL_NOT_LESS_OR_EQUAL - driver error, memory address is not available;
0xF3 - DISORDERLY_SHUTDOWN - Windows was unable to shut down due to lack of memory;
0xC0000135 - STATUS_DLL_NOT_FOUND - error loading the library;
0xC000021A - STATUS_SYSTEM_PROCESS_TERMINATED - error in a service running in user mode;
0xC0000221- STATUS_IMAGE_CHECKSUM_MISMATCH - the driver file was not found or damaged.

If your blue screen of death error is in this list no, then you can find it on technical websites Microsoft support. It contains the most explanatory probable causes failure for each error, as well as interpretation of the BSoD parameters - this is necessary for high-quality troubleshooting of the problem leading to the appearance of BSoD.

Blue screen of death, what to do

Why does the blue screen of death appear? There can be a lot of reasons. IN general case BSoD occurs when a critical error occurs while executing kernel code or driver code in kernel mode.

The blue screen of death appears, for example, when any changes have been made to the computer’s hardware: replacing or installing a video card, audio adapter, hard drive, controllers and devices PCI bus And PCI Express. The driver for these devices may be poorly compatible or incompatible with the existing computer configuration, which leads to problems and BSoD.

The only thing that helps when BSoD occurs is restarting the computer, as a result of which all unsaved user data will be lost.

The user has the option to manually trigger the BSoD. This is only done if there is no other way to detect a system malfunction. To call BSoD, it is possible to assign a specific combination of hot keys. Therefore, under unfavorable circumstances, the user may inadvertently cause a BSoD to appear.

The manual BSoD procedure should not be abused to avoid loss of information or software problems. In addition, a blue screen of death caused artificially will not display needed by the user information. You may also encounter difficulties in the hardware dependence of this procedure: in particular, there are restrictions on calling BSoD from keyboards that have USB connector. More information about inducing a blue screen of death can be obtained from Microsoft document Q244139.

So, the blue screen of death appears, what should you do in this case? The only thing you can do is this moment- this is to reboot. Next, if you are enough advanced user and are not afraid of working with debuggers (debuggers), that is the solution. To determine the cause of BSoD, Microsoft has developed comprehensive solution Debugging Tools for Windows with support for 32 and 64-bit OS, which is included in Microsoft SDK for Windows.

Causes of the Blue Screen of Death

Changing BIOS settings made on a quick fix may also be the cause of BSoD. If you don't remember exactly what changes you made (especially if you made multiple changes), then the best solution To avoid the blue screen of death error, you will need to set the BIOS settings to the default state.

There are viruses that are created to attack the main boot entry(MBR) and boot sector. They can also cause problems and blue screen of death errors. You can check your computer for viruses by booting from recovery disk With installed antivirus. Many antivirus development companies, such as Kaspersky Lab, offer in their solutions the function of creating a CD from an existing distribution. In addition, you can already download finished image from the company's servers. Also you can check the MBR status antivirus utility AVZ. You can read more about working with the utility at the link.

Problems with RAM. Diagnostics

Often faulty and sometimes unequal RAM modules can cause the Blue Screen of Death error to occur. If you notice that after installing, reinstalling, or replacing RAM modules, the OS does not boot or a blue screen of death appears, you can try putting the memory modules in other DIMM slots or swapping DDR sticks - this often solves the memory problem. However, the problems may lie elsewhere, and the cause of this can be identified by diagnosing the RAM using standard means checks Windows memory. The utility is available in Windows 7 and Vista (for Windows XP you can use the Windows Memory Diagnostic utility)

Let's see how the diagnostic tool works:

2. In the window that opens, select “Windows Memory Checker” from the list (usually the third one from the bottom).

3. In a new window, Windows will ask you to choose from two options: “Restart and scan (recommended)” and “Scan the next time you turn on the computer.”

4. Close, that's it open source software to make sure you don't lose any data, and click "Reboot and check (recommended)."

The computer restarts and the memory test begins. Typically the test is performed in two passes. The screen shows both the percentages for the current pass and the final ones. Once the test completes, it will reboot and present the test results.

Rice. 3. Checking your computer for memory problems There is another possibility - to test the status of the RAM with boot disk(Windows Vista and Windows 7 only). For this:

1. Go to BIOS and set CD-ROM (DVD-ROM) as the first boot device V BOOT menu, then exit the BIOS, saving the settings.

2. After the reboot, the bootloader will display the message “Press any key to boot from CD”, press any key.

3. Wait while Windows downloads the files. In the window " Windows installation» Click Next.

4. Select "System Restore", wait.

5. Leave all the settings in the “System Recovery Options” window as default (“Use recovery tools...”) and click “Next”.

6. From the list provided, select “Windows Memory Diagnostics”.

7. In the new window, select 1 of 2 options. For example, "Reboot and check (recommended)" to start checking memory immediately.

The computer will reboot and the memory test will begin.

Hard drive diagnostics

Problems with the hard drive (HDD) can also cause the Blue Screen of Death error. Windows utility CHKDSK allows you to check your hard drive for errors and bad sectors. Using this utility it is possible to restore damaged HDD sectors. To run the scan, follow these steps:

1. Open Windows Explorer.

2. Click right click mouse over the section you want to check and select "Properties".

3. In the new window, select the “Service” tab.

4. At the top of the tab, click on the “Run check” button.

5. A new window “Check disk “Disk name”” will open. The user can choose 1 of 4 options for checking the disk, depending on which items he checks. If you just want to know if your disk has errors, uncheck the top point. In that Windows case won't fix it system errors. You can also conduct a comprehensive study and restore damaged HDD sectors by selecting both options. Attention! Windows will not be able to automatically correct system errors and restore damaged sectors while the selected partition is active, i.e., in use. Therefore, a system reboot may be required to complete the test. In this case, in the warning window that appears, click on the “Schedule disk check” button. After the PC restarts, the disk check and user-selected actions will be performed. To get more detailed information For information on how to use the CHKDSK utility, check out this .

6. Click the “Launch” button and wait for the test results.

After checking, a new window will display both brief and detailed information about the status of the tested partition.

Rice. 4. Checking the hard drive If the CHKDSK utility has done its job, and disk errors occur again, you can carry out more deep testing. To do this, you will need to resort to utilities developed by hard drive vendors.

In addition to the ability to externally diagnose the condition of a disk drive, all modern HDDs and SSDs ( solid-state drive) are manufactured with the manufacturer’s ability to self-monitor and self-test their condition, as well as estimate the time of expected failure of the device. This is S.M.A.R.T technology. To access the diagnostic data of this technology, you need to use one of the programs that can read the data transmitted by the disk controller program. There are paid and free programs with support for this possibility. One of the modern free programs is CrystalDiskInfo

Rice. 5. S.M.A.R.T. using CrystalDiskInfo As you can see in the screenshot, the program provides all the data on the disk, including current temperature, number of inclusions, total number hours of work. Below in the list are technical data that can be used to judge the physical wear of the disk. Current and worst values ​​- real indicators of this disk at the moment and ever, respectively. The threshold is a value below which the manufacturer of a given hard drive cannot guarantee stable and uninterrupted operation of the device.

Despite the seeming flawlessness of the technology, in practice many companies and individuals complain that hard drive failure often occurs when normal indicators S.M.A.R.T. Therefore, you can trust this technology only with an eye to the possible erroneousness of the data, which, nevertheless, does not detract from all the advantages of this technology.

Memory dump

For a qualitative perception of the information below, let’s define the concept of a memory dump. Memory dump - the contents of the working memory of one process, kernel or entire OS. A memory dump contains technical information about the state of a system or an individual program.

It should also be noted that memory dumps come in different forms.

By default, in modern operating systems such as Windows XP/Vista/7 (from now on we will only consider these Windows operating systems as the most common), when the blue screen of death appears and you reboot the computer, a debugging information record is created in the kernel memory dump file MEMORY. DMP. It will contain everything necessary information sufficient to diagnose the cause of the failure and prevent it in the future.

Full memory dump contains comprehensive information about the system status and problems. The OS also saves this information to the MEMORY.DMP file by default.

A small memory dump can be used to create a dump file. It contains only general system information, which is often not enough to correctly diagnose the cause of the blue screen of death error. It is appropriate to create a small memory dump file only in cases where disk space is extremely limited. If you have no difficulty with disk space, then it is better not to use a small memory dump to create a dump file.

So, by default, when Windows XP/Vista/7 crashes, it creates a memory dump file MEMORY.DMP and writes to it debugging information, parameters of the failure that occurred. The MEMORY.DMP dump file is then saved to the %SystemRoot%. Subsequently, the dump file can be sent to the developers to find out the cause of the BSoD.

The user can also do self-configuration saving technical information in case of system failure. Let's configure the OS recovery options. To do this, we sequentially perform the following steps:

If you are using Windows 7 or Windows Vista:

1. Go to “Start”, “Control Panel” and select “System” or right-click on the “Computer” icon and select “Properties”.

2. At the bottom of the left column, click “ Extra options systems."

3. Go to the “Advanced” tab.

If you have Windows XP, then do everything the same, except for the 2nd step.

Rice. 6. Configuring OS recovery parameters The new “Boot and Recovery” window presents OS boot parameters and actions if it fails. Here you can choose the most suitable parameters recovery after BSoD. In particular, the user can select from which memory dump the dump file will be written. And also change the name of this file and the directory where it will be saved. Note that you should not change the name of the dump file if you intend to subsequently send it to Microsoft or other developers for analysis.

1. The problem of compatibility of computer hardware drivers, although not the only one, is the main reason why the blue screen of death appears. Therefore, it is necessary to constantly update your computer's device drivers. Moreover, what is important, this should be done only from the official websites of hardware manufacturers or from the websites of their partners. Otherwise, you risk getting a virus or a malfunction of the device for which the driver is intended.

2. Install software products only well-known and well-established companies that value their reputation and are responsible for the stable and uninterrupted operation of their software.

3. Be sure to download everything Latest updates programs and OS to eliminate incompatibilities and vulnerabilities. The blue screen of death also appears when a program cannot interact correctly with the system kernel: this can be incorrectly written code, leading, for example, to a loop, or vulnerabilities through which viruses, exploits, rootkits and other infections can penetrate into the program code, capable of, among other things, damaging hardware.

4. Viruses are one of the possible reasons BSoD. For stable operation OS and programs use good antivirus with firewall ( firewall) or a comprehensive solution of the Internet Security class.

5. When and frequent appearance blue screen of death errors, trust the solution to the problem to specialists if you yourself are not 100% confident in your abilities. There is absolutely no advertising in this. The point is that if you use licensed software, you are entitled to free technical support. In addition, in addition to Microsoft Corporation, today such services are provided, for example, by some antivirus developers.

6. When a BSoD appears and the computer is subsequently restarted, all unsaved data is lost. To ensure the security of your information, please follow backup your data to external drives.

7. Computers, like people, do not last forever. They also get sick, grow old and die. Computers that are too old and obsolete can jeopardize your work efficiency. Moreover, a computer should give its user pleasure, and if it constantly fails, which is more typical for experienced PCs, then there is no need to talk about it. Blue screens of death appear more often on obsolete computers, when hardware developers stop supporting their products.

8. Computers need cleaning. It is necessary not only to wipe and blow through the computer components, but also to clean the system of accumulated temporary files OS and programs, as well as other things information garbage, which is of no value. This can also prevent BSoD.

Take another look at the BSoD images at the beginning of the article. The main purpose of the blue screen of death is to warn the user about problems with his computer and prevent possible negative consequences. Therefore, there is no need to be afraid of BSoD, but you need to think in this way: blue screen of death, what to do? And then you need to work with this problem until it is eliminated.

I hope, dear readers, you liked the article and found it useful. Health to you and your computer!

Blue screen of death, also known as BSOD and blue screen of death, is Windows’ reaction to critical errors in the computer’s operation. White writing on a blue background suddenly appears on the screen, after which the device usually reboots, freezes, or turns off.

After restarting, the system works fine for some time. But then, if the error is not resolved, the BSOD appears again.

Sometimes this condition is caused by errors in drivers or failure of computer hardware. The reasons may also be a failure system settings, viruses or even installed programs.

What to do if a blue screen of death appears

They can help you special services, built into the operating system.

If you have Windows 10, go to Start → Settings (gear) → Update & Security → Troubleshoot. Scroll to the bottom of the list of available services and select Blue Screen. Click “Run the troubleshooter” and follow the system prompts.

If you have more old version The OS or the tool mentioned above did not work, open the Windows Control Panel and go to the Security and Maintenance Center. In some versions of the OS, this path may look like this: “Control Panel” → “System and Security” → “Action Center”.

Expand the Maintenance tab and see if the solution recommendations appear here Windows problems. If yes, use the suggested tips.

If all else fails, move on to the next step.

There may be hundreds of Blue Screen of Death occurrences various reasons and each has its own solutions. Having learned cause of BSOD on your computer, you can find the best way to solve a problem.

On the screen death of Windows displays the code of the error that caused it. It can appear as a series of numbers and letters (0x0000000F) or a combination of various words written in uppercase and often connected by underscores (SPIN_LOCK_ALREADY_OWNED).

You need to enter the error code in a search engine and thus find individual instructions for fixing it. There may even be a special QR code on the blue screen. By scanning it through mobile device, you will be taken to the Microsoft website with interactive assistant to solve the problem.

If the computer restarts immediately after the blue screen appears and you do not have time to write down the error code, disable automatic restart. To do this, right-click on the “This PC” icon and select “Properties” → “Advanced system settings”. In the window that opens, go to the “Advanced” tab, click “Options” and uncheck the “Perform automatic restart” checkbox.

If you don't want to search the necessary instructions and delving into it or the solution found on the Internet does not help, use the methods listed below.

3. Try simple universal measures

These general measures affect many system parameters and help restore it. normal work. They can also fix errors that lead to the blue screen of death.

1. In system settings, go to "Center" Windows updates» and check for updates. If they are available, install them.
2. Check the system using .
3. Update your drivers. You can go to your computer manufacturer's website and download all the drivers for self-installation. But you can also use free services like

Good afternoon.

Although, he’s probably not that kind, since you’re reading this article... In general, the blue screen of death is not a pleasant pleasure, especially if you spent two hours creating a document, but autosave was turned off and you didn’t have time to save anything... Here you can turn gray if it’s a coursework and you have to hand it in the next day. In this article I want to talk about step-by-step restoration of your computer if you are tormented by a blue screen with enviable regularity...

And so, let's go...

Probably, you need to start with the fact that if you see a “blue screen”, this means Windows has completed its work with a critical error, i.e. There was a very serious failure. Sometimes it is quite difficult to get rid of it, and only reinstalling Windows and drivers. But first, let's try to do without it!

Eliminating the blue screen of death

1) Setting up your computer so it doesn’t reboot during a blue screen.

By default, Windows OS, after a blue screen appears, goes to reboot automatically without asking you. There is not always enough time to record an error. Therefore, the first thing we will do is to prevent Windows from rebooting automatically. Below we will show how to do this in Windows 7, 8.

Open the computer control panel and go to the "System and Security" section.

Here we are interested in the boot and recovery options.

In the center of the window, under the heading "system failure" there is an option "perform automatic reboot". Uncheck this box so that the system does not reboot and gives you the opportunity to take a photo or write down the error number on paper.

2) The error code is the key to solving the error

A blue screen of death has appeared in front of you (by the way, in English it is called BSOD). You need to write down the error code.

Where is he? The screenshot below shows the line that will help determine the cause. In my case, the error is like "0x0000004e". I write it down on a piece of paper and go look for it...

I suggest using the website http://bsodstop.ru/ - all the most common error codes are here. By the way, mine was found too. To solve it, they recommend that I identify the faulty driver and replace it. The wish, of course, is good, but there are no recommendations on how to do it (we'll look at it below)... This way you can find out the reason, or at least get very close to it.

3) How can I find out the driver that caused the blue screen?

In order to determine which driver caused the failure, you will need the BlueScreenView utility.

It's quite simple to use. After launch, it will automatically find and show errors that were recorded by the system and reflected in the dump.

Below is a screenshot of the program's operation. Errors when a blue screen occurred, date and time are shown at the top. Select the desired date and see not only the error code on the right, but also the name of the file that caused the error is shown at the bottom!

In this screenshot, the file "ati2dvag.dll" somehow did not suit Windows. Most likely you need to install newer or older drivers on the video card and the error will disappear by itself.

Similarly, step by step, you will be able to identify the error code and file that is causing the crash. And then you can try to replace the drivers on your own and return the system to its previous stable operation.

What to do if nothing helps?

1. The first thing we try to do when a blue screen appears is to press some keys on the keyboard (at least that’s what the computer itself recommends). 99% that nothing will work out for you and you will have to press the reset button. Well, if there is nothing else left, click...

2. I recommend testing the entire computer and RAM in particular. Very often a blue screen occurs because of it. By the way, wipe its contacts with a regular eraser, blow off dust from the system unit, and clean everything. Possibly due to bad contact RAM connectors with the slot where it is inserted and the failure occurred. Very often this procedure helps.

3. Pay attention to when the blue screen appears. If you see it once every six months or a year, does it make sense to look for reasons? If it starts to appear after every Windows boot, pay attention to the drivers, especially those you recently updated. Most often, problems arise due to video card drivers. Be sure to update them, or install more stable version, if this took place.

4. If the computer displays a blue screen immediately at the moment Windows boots, and not immediately after it (as in step 2), then most likely the system files of the OS itself have been corrupted. To restore, you can even use standard system recovery utilities using checkpoints.

5. Try going to safe mode- perhaps from there you will be able to remove the faulty driver and restore system functionality. After that, the best option will try to restore Windows system using the boot disk from which you installed it. To do this, start the installation, and during it select not “install”, but “restore” or “update” (depending on the OS version, the wording will be different).

6. By the way, I personally noted that in newer operating systems blue screens occur much less often. If your PC meets the specifications for installing Windows 7, 8 on it, install it. I think there will be fewer mistakes overall.

7. If none of the previously suggested solutions helped you, I’m afraid that only reinstalling the system will improve the situation (and then only if there are no hardware problems). Before this operation, you can copy all the necessary data to flash drives (booting using a Live CD, not from your hard drive) and calmly reinstall Windows.
