Blue window of death. What to do if a blue screen appears on your laptop

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

Special services built into the operating system can help you.

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.

The appearance of a blue screen of death can have hundreds of different 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 may look like a series of numbers and letters (0x0000000F) or a combination different words written in uppercase and often associated with 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, click right click mouse over the “This PC” icon and select “Properties” → “ Extra options systems." In the window that opens, go to the "Advanced" tab, click "Options" and uncheck "Run automatic reboot».

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

How to find out the cause of the appearance blue screen of death (BSOD), as well as options for eliminating BSOD from your computer

Blue Screen of Death (BSOD) Windows. Theory.

Blue screen of death(Blue Screen of Death, Blue Screen of Doom, BSoD) – message about critical system error Windows, as a result of which the operating system cannot continue working and goes into a forced restart without saving data.

Preparing for Blue Screen of Death (BSOD)

It can be caused by a malfunction of some hardware or software failure (drivers most often). Screen of death errors are displayed on the screen with a blue background, on which the REASON for its occurrence is written. Therefore, the most important task will be to extract from this message the lines after the second or third paragraph, written in CAPITAL LETTERS through underscore PAGE_FAULT_IN_NONPAGED_AREA) and lines after Technical information: that begin with *** For example:
*** STOP: 0x00000050 (0x8872A990, 0x00000001, 0x804F35D7, 0x00000000)
*** SPCMDCON.sys - Address FBFE7617 base at FBFE5000, Date Stamp 3d6dd67c)
Lines to remember in the blue screen of death:

An equally important task is to save a dump file that contains the error report blue screen of death (BSOD). By default it is enabled in both Windows Xp and Windows Seven(7), but if you have it turned off then:
If the operating system is Windows 7: Right-click on “My Computer” -> Properties -> Advanced system settings -> “Advanced” tab -> After the “Startup and Recovery” lines, click on “Options” -> check the “Record event” box V syslog" and uncheck the "Perform automatic reboot" checkbox. Do as in the image

If the operating system is Windows Xp: Right-click on “My Computer” -> Properties -> “Advanced” tab -> After the “Startup and Recovery” lines, click on “Options” -> check the box “Write event in system log” and Uncheck the “Perform automatic reboot” checkbox.

Next time blue screen of death (BSOD) Firstly, the computer will not automatically reboot, and secondly, it will save a dump file in which information about the blue screen of death (BSOD) will be stored.

Determine the cause of the Blue Screen of Death (BSOD)

After completing the steps, turn on the computer and try to boot Windows.
If when loading you immediately get a blue screen of death, then the next time you reboot we boot into safe mode, just select not safe mode, and “Disable automatic reboot on system failure”


Let's write down the lines that we need on a sheet of paper.

IN in this case As you can see, the system file SPCMDCON.sys is to blame. Therefore, the first thing you need to do is delete it or, on the contrary, restore it. To do this, boot from a bootable Live Cd or bootable Live usb and delete it manually (or restore it). We are looking through Live boot disk on the Windows drive SPCMDCON.sys and rename it, for example, SPCMDCON(2).sys. Reboot the computer. If it helps and everything is ok, I congratulate you, if not, we continue to fight the blue screen of death (BSOD) using the same method until we defeat it.
If the Blue Screen of Death (BSOD) does not immediately appear and Windows boots, then check the Dump file. To do this, download BlueScreenView
Launch BlueScreenView.exe. The drivers that caused the blue screen are highlighted in red.


They must be removed in manual mode and then install newer ones (often causes a blue screen of death of the video card driver)

Blue screen of death (BSOD) during games or after different periods of time (reinstalling Windows does not help)

If the situation is such that everything has already been experienced and reinstalling Windows and other methods, but the blue screen does not go away, then the problem is in the computer hardware. CPU and RAM tests will help you here. This may be a reason to purchase new video card without replacing a power supply that is not designed for such a load, or a faulty RAM stick. To make things easier, here is a list of the most common Blue Screen of Death (BSOD) errors.

The most common Blue Screen of Death (BSOD) errors – taken from the Microsoft website

1. KMODE_EXCEPTION_NOT_HANDLED- A kernel mode process attempted to execute an invalid or unknown processor instruction. May be due to hardware incompatibility, hardware malfunction, driver or system service errors.
2. NTFS_FILE_SYSTEM- crash when executing driver code file system ntfs.sys. The reason may be a violation of data integrity on the disk (failed cluster) or in memory, or damage to the IDE or SCSI drivers.
3. DATA_BUS_ERROR- a parity error was detected in the RAM. The reason is defective or incompatible equipment, for example, a failure in the second level cache chip or in video memory. It may also be associated with an incorrectly working or incorrectly configured driver, or a disk failure.
4. IRQL_NOT_LESS_OR_EQUAL- a kernel mode process tried to access a memory area using an IRQL (Interrupt Request Level) that was unacceptably high for it. May be caused by errors in the driver, system service, BIOS, or incompatible driver, service, software(for example - antivirus).
5. PAGE_FAULT_IN_NONPAGED_AREA- the requested data is not in memory (for example, the system looks for the required data in the paging file, but does not find it). Typically associated with hardware failure (defective memory), file system corruption, error system service or antivirus.
6. KERNEL_STACK_INPAGE_ERROR- cannot read from the swap file in physical memory the requested memory page. Reasons - defective sector of the file virtual memory, controller failure hard drives, there is not enough disk space, incorrect connection hard drive, interrupt conflict, RAM defect, virus.
7. MISMATCHED_HAL- the hardware abstraction level (HAL) and the system kernel do not match the computer type. Most often associated with a situation where original system install a second processor, forgetting to manually update HAL and ntoskrnl. It may also be caused by a version mismatch between hal.dll and ntoskrnl.exe.
8. KERNEL_DATA_INPAGE_ERROR- the requested data page cannot be read into physical memory. Reasons: defective sector of the virtual memory file, hard drive controller failure, RAM failure, virus, disk controller failure, defective RAM.
9. INACCESSIBLE_BOOT_DEVICE- during the boot process the OS was unable to access system partition. There can be many reasons for this common failure: a defective boot disk or disk controller; equipment incompatibility; boot virus; error in the file system, for example - in a table Partition Table; Damage or absence of a file necessary for downloading, for example - NTLDR; missing hard drive controller driver or mismatch current driver installed equipment; included in BIOS mode DMA; included in CMOS Setup mode for changing drive letters DRIVE SWAPPING; resource allocation conflict between the disk controller and another device; corruption of loading driver data in system registry; installing the system on a partition beyond the first 1024 cylinders of the hard drive; error in boot.ini file.
10. UNEXPECTED_KERNEL_MODE_TRAP- occurrence of a trap not supported by the kernel or fatal error(like division by zero). Hardware failure or software failure.
11. STATUS_SYSTEM_PROCESS_TERMINATED- a failure in a service running in user mode. The failure may be due to incorrect work application programs, drivers, third-party system services.
12. STATUS_IMAGE_CHECKSUM_MISMATCH- the driver file is damaged or lost, or system library. May be caused by a file system failure or accidental deletion system file.

An error or crash may occur while loading or running the Windows operating system, resulting 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 the system unit; in this case, 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 verification string and error verification code, in order to find information on them on the Internet.

System Setup

So that if a critical failure occurs in operating system To be able to diagnose the problem and fix it, 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:

• right-click on the “Computer” icon and then select “Properties” from the menu that appears;
• in the left menu active window select “Advanced system settings”;
• click on the “Advanced” section;
• in the “Boot and Recovery” field, select “Options...”;

  

• in the “Boot and Recovery” window, uncheck the box next to “Perform automatic reboot”;
• Additionally, you need to change and save the options for saving debugging information. To do this, in the “Write debugging information” window, it is recommended to select the “Small memory dump (256 Kb)” value. It is advisable not to change the directory into which mini dumps will be loaded. The default is C:WINDOWSMinidump.

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 go a long way toward identifying what caused the failure and what the 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's important to take the test of 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 operates normally without failures, then 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

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 that arise related to the software are resolved in a similar way. 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 products on the same 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 the Debugging Tools for Windows) how to analyze crash memory dumps.



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 be displayed with dump analysis;
• analyze the memory dump in detail;
• It is especially important to pay attention to the “Bugcheck Analysis” section, which displays possible reason 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 due to damage to some system files or lack of 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 - this is hexadecimal code errors and their description.

Quantity 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 that have detailed information about errors, and describes 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 the 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 processor command;
• 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 a certain sequence of characters.

The appearance of BSOD indicates 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.

Hello friends! If you know firsthand what a blue screen of death is, and what’s worse, you often encounter it, then this article should help you. Now I will try to write in detail about why can they appear frequently? blue screens death, and how to check RAM for mistakes standard checking tool Windows memory.

You may ask why am I writing about blue screens and RAM diagnostics in one article? Yes, because RAM, or rather problems with it, are very often accompanied by blue screens, with various errors, and in different time. This is, of course, my opinion, but in about 60% of blue screens, problems with RAM are to blame.

What to do if blue screens appear frequently?

As the saying goes, real story:). My friend has almost new computer, and he was already taken out of nowhere. They appear at any time, that is, there is no certain pattern that something was done and there was an error. A blue screen may appear once a day, or immediately when you turn on the computer, or maybe after several hours of operation.

As he already noticed, these error screens appear most often 0x0000000A And 0x0000008e(there may be other error codes). Of course, only a reboot helps. But it doesn't save for long.

It’s almost impossible to work on such a computer; you don’t know when this error will pop up.

I advised you to scan your RAM for errors, at least with a standard one Windows tool. After he launched the test, not even 15 minutes had passed (and RAM takes a long time to test) when a message appeared stating that problems with RAM were detected. In fact, if at least some memory errors are found, then there is no point in continuing scanning. Here is the reason for the errors, in the form of blue screens.

I’ll say right away, so as not to forget later, it will no longer be possible to fix the RAM. It can only be replaced. And utilities like standard remedy memory diagnostics, and a utility such as Memtest86+, which I will write about in a separate article, does only diagnostics, but not repair.

Checking memory with a standard utility in Windows 7

Now I will write about how to check the RAM standard utility, which is already in the operating room Windows system. I'll show you on Windows example 7. It's called.

Open “Start” and type in the search bar:

Run mdsched.

Press “Reboot and check”.

The computer will reboot and the RAM check will automatically begin.

I warn you right away that the verification may take a long time. After the test, the computer will turn on itself and a report on the test result will appear. This window appeared after checking the RAM from a friend.

After such messages, you need to change the RAM. If you have two (or more) sticks of RAM, then you can leave, for example, only one and run the check again to find the problematic module.

You can also borrow a RAM from a friend and work with it for a while. See if blue screens appear. If yes, then look for other reasons, but if everything is fine, and most likely it will be, then buy new RAM.

That's all, I also want to wish you good luck, in this matter, it will come in handy :). And congratulate you on the upcoming New Year holidays!
