BSoD or "Blue Screen of Death" in Windows can appear for various reasons. Starting from a failure in a separate program, ending with a breakdown of important equipment. If you saw BSoD only once, it's too early to sound the alarm. But if the failure is regular, then there are some problems with the computer. And you need to pay attention to the information that is shown in the error.
You quietly worked at the computer, and saw the "Blue Screen of Death" in Windows 7. What to do in this case? You don't have to restart your PC right away. Look at the error code. From it you will understand that it is “broken”. And you can eliminate the cause of the failure.
When the BSoD appears, pay attention to the sections:
Remember what happened before the Blue Screen of Death arose. That way you can figure out what to do with it. For example, you connected a new device, installed a program, updated the system, or downloaded unlicensed drivers for Windows. If it was after this that problems began, then you found the culprit. You can also determine the cause by looking at the error codes.
Here's what's causing the crash:
The cause of the problem may be a defective hard drive.
To understand how to get rid of the problem, you need to look at the error codes. The Blue Screen of Death provides the necessary information. But the list of such numbers is huge. After all, anything can break. And it is not clear what to do in this case. Here are the most common failures:
Death screen example
The list is quite long. It has hundreds of different rooms. You can enter the error code in the search engine to find out more information. Or look at it on the site "bsodstop.ru" ("BSoD: error description" tab). There are also instructions that describe what to do in each situation.
If the same failures occur with different objects (the codes are the same, but the file names are not), most likely the problem is not in the system, but in the hard drive. Back up your important data as soon as possible. If they end up in a damaged sector, it will be difficult to restore them.
How to find out the failure number if the computer restarts when a BSoD occurs? And you just don't have time to read the message.
Blue screen codes can be viewed in dumps. They are located in the Windows\Minidump system directory. To open these files, you need the BlueScreenView program. Find it on the Internet, install and open it. It will scan the dumps and list them. Files that contain information about the failure will be marked in red.

If the equipment is broken, it is unlikely that it will be possible to fix it at home. But sometimes it is enough to turn it off and on again. Suppose, according to the error codes, it became clear that there is no access to RAM. Here's what to do:
The same can be done with a hard drive, and with a video adapter, and with a sound card. But if you are unfamiliar with the internal structure of a computer, it is better to entrust it to professionals. It is not necessary to pull out all the parts from the system unit one by one.
If it does not help, then the equipment has become unusable. It needs to be changed.
Very often BSoD appears when hard drives or other external devices are connected to the computer. How to fix the "Blue Screen of Death" in this case? Turn off equipment. Try plugging it into a different port. See how it appears in Device Manager. Check if there is an exclamation mark next to the model name. Update drivers.
Perhaps the problem is not with the computer, but with the port controller. If it is faulty, it must be disabled.
Run System Disk Check and Repair. For this:
Go to "Properties"
Click on "Perform verification"
Check the box next to "Repair bad sectors"
Here's how to remove the "Blue Screen of Death" if the problem is in the system itself or the programs installed on it:
Recovery points
The system will rollback. It will return to the state it was in before the errors occurred.
CCleaner
If the Blue Screen of Death appears immediately after turning on the computer, you will not be logged into the system. And it will be difficult to fix something. Therefore, you need to start the PC from a boot disk or drive. If you don't have one, use the Windows installation CD. A free program from DrWeb - "Live Disk" is also suitable. It can be downloaded from the freedrweb.com website:
This will work if the problem is due to a software glitch. But it won't help if the equipment breaks down.
It is necessary to take care of the system and computer, even if there are no problems. Regularly check the disk for errors, remove unnecessary garbage from it, clean the registry. Don't try to improve PC performance if you don't know how. If you take precautions and monitor the status of the system, the Blue Screen of Death is unlikely to bother you.
You can deal with some failures yourself. But if the BSoD appeared due to a hardware failure, it will have to be changed.
The screen of death is caused in Windows 7 by system errors that are classified as critical. The OS hangs and the user's last changes are not saved.
The situation is not the most pleasant, but it is often found in computers with the "Seventh" modification of the system.
There is no general algorithm of actions to eliminate this problem, since it depends on the causes that caused it. The following are specific recommendations that should be taken to effectively resolve the situation.
All the abundance of causes that cause BSoD are classified into two large parts:
The first includes failures in system services, incorrectly installed software (including drivers that ensure the normal functioning of equipment), PC virus infections, software conflicts, etc.
The second part of the reasons that cause a blue screen in computers on Windows 7 lies in the hardware. Record holders in popularity are such important PC components as a hard drive and RAM.
Often, after a user introduces an additional RAM bar into a PC, or due to poor contact in the slot, a blue background with white letters will not be slow to greet the owner of the computer. Also, it is not uncommon for problems with a hard drive to cause a critical error and an OS freeze.
The blue screen itself in Windows 7 is informational. Its text contains recommendations for troubleshooting and notifies the user of the specific error codes that caused it to occur.
That is why it is required to carefully study all the inscriptions displayed by the screen of death. By copying or memorizing the error codes from the bottom of the screen, you can surgically accurately diagnose and quickly get rid of the problem.
Unfortunately, often the user does not have time to familiarize himself with the output report, so this guide begins by accepting the cancellation of the automatic restart of the PC after an error occurs.
If the user did not have time to capture the necessary information from the screen, then a little PC setup will be required.
After that, it will be possible, having learned the code, to find an effective “medicine” that can cure an iron friend.
You need to do the following:
It is recommended to study the meaning of the error code on the resource "bsodstop.ru". For example, "0x0000004e" may appear due to an incorrectly installed driver.
To find out exactly which software caused problems in the system, you should use the BlueScreenView application, which automatically detects files that cause a critical error. The user only needs to install and open the application.
By the detected file, you can find out for which equipment you need to reinstall the drivers. From the above figure, we can conclude that the difficulties with the graphics accelerator, since "ati2dvag.dll" is associated with the video card.
In this case, installing the correct software for the video accelerator will get rid of the death screen.
After reinstalling the driver, you need to restart the PC. If it was not possible to fix the problem, then there are still other reasons.
Often an error occurs after updating or installing a new program, while the best way out of the situation is to roll back the OS.
A new program or game is also a common culprit in system failures. In order to return the OS to a working state, it is necessary to perform the following sequential steps:
Specialists from Microsoft do not stand aside and make their efforts to troubleshoot problems that cause BSoD.
They continue to support the already outdated "Seven" and release upgrades that include "fixes" that correct system errors that cause a blue screen.
To update, you will need to do the following:
The next most popular cause of problems is the banal lack of memory in the system partition of the hard drive. Checking this version will not take much time.
On the official resource of the developer of Windows 7, it is written that at least 100 Mb of free space on the system volume is required for its operation, however, practical experience has shown that for the normal operation of the Seven, it is required to keep a fifth of the system volume free.
To make sure there is enough space in the partition, you just need to open "Computer" in the explorer.
After making sure that there is enough space for the functioning of the OS, you should proceed to the analysis of the presence of system errors through the event log.
To do this, you need to take the following steps:
Often, simply disabling the antivirus will fix the problem. If, after deactivating the security application, the blue screen stops appearing, then a complete removal of the antivirus will be required.
Malicious utilities also cause critical errors, and regular scanning of the PC for their presence is required. Many antivirus developers have versions of programs that operate from removable media.
For example, "AVZ". By burning the application to a CD or USB flash drive, you can treat your PC from malicious utilities.
Incorrectly entered parameters in the BIOS also often cause a failure. You can fix the situation by resetting the BIOS settings to the initial state - “default”.
The simplest revision of the wear of the loops and the correctness of their connection sometimes allows you to quickly identify the cause of the failure.
If the user has the appropriate experience, it is required, having opened the system unit (SB), to check the connections of all computer components.
For example, when, based on the results of a careful review of the information displayed on the blue screen itself, it is found that there is no access to RAM, the following actions will need to be performed:
Similar measures can be taken with other PC components, for example, with a hard drive and sound - video cards. If there is no positive result, then this component may fail and a replacement with a new one is required.
Hardware diagnostics can be performed using special utilities. For example, "Windows Memory Diagnostic" allows you to identify problems with RAM.
The application writes a boot disk image. This ISO must be cut into a CD and booted from it to a PC. The program will carry out testing in a cyclic mode.
To stop the analysis, you need to reboot. Also in Windows 7 there is a built-in program for analyzing RAM. In order to use it, you need to follow the following steps:
To minimize the risk of BSOD, the following is recommended:
Hello, friends! Finally, we got to the topic of blue screens in Windows. This is familiar to every fan of Microsoft operating systems. When I first started my acquaintance with computers, I thought that it should be so. Once a week or two to catch a blue screen is normal. Technique after all, as they say, not iron. But no. As it turned out, this is extremely rare for good users. And the less often the better. Moreover, the OS is trying in every possible way to help you with this by displaying hints on Windows 7 blue screen of death(in the information on the screen there is much less) about which you can and with great probability solve your problem. This is what we will do with you.
While we are not head over heels in the technical moments, I will say. The main thing is to determine the driver and the error code that caused the blue screen. This is what most of the article is devoted to. Then, using the help of the old and kind, look for answers. This is the magic formula for eliminating critical errors in Windows operating systems.
A memory dump is an image of memory or its contents at a specific point in time. Accordingly, a minidump or a small dump is part of the contents of the memory. Most likely important.
On the Advanced tab, under Boot and Recovery
Click OK
All. The computer is configured to be blue screen friendly.
In principle, this is already enough to diagnose and search by error code.
Now you need to tell where to look and what to write down.
The figure shows a typical.
What is there:
Now you can start searching for information without worry:
Here you can wish you success and patience. Don't give up because you are not the only one. For sure, your mistake has already been sorted to the bone on some forum.
The BlueScreenView utility will help us get useful information by analyzing the dumps.
You can download it from the official site http://www.nirsoft.net/utils/blue_screen_view.html
You can see the bit depth of your Windows in the properties of your .
Start > Computer > Properties section System Type
You can read more about the bitness of Windows in.
In the table below you can download your language for the program. Download, unpack and copy the BlueScreenView_lng.ini file to the program folder. Restart the program and it is in your native language.
Russified versions can be downloaded below
BlueScreenView determines the location of minidumps by default
C:\Windows\Minidump
If you have other dumps (for example, you want to analyze dumps from ) you can copy them to the same folder. If you do not want to interfere with dumps of different computers, then you can copy them to the root on drive C and delete them after analysis.
In any case, you must specify the location of them
The first thing to do is this. Second, it's on the motherboard. After that, work and see if there are blue screens. If they do, read on.
You can break the causes of blue screens of death in Windows into three components:
One of the most common causes of blue screens in this category is RAM errors. Will have to test. How to do it - .
There may also be problems with the storage system. In other words - your wants to retire. Need to be produced. And yes. Lack of hard drive space can also cause a BSOD.
After we have tested all the components it would be nice to give a load to the whole system using the same eg.
If all the components individually pass the test, and if the total load fails, then it may fail. For the duration of the test, it is desirable to install a more powerful PSU. At the same time, it would be good to measure the temperatures and if they are sky-high, then either carry the component under warranty if any.
Another great option is to disconnect all the connectors from the back wall and inside it (from the motherboard, video card, and from optical drives) and reconnect. Perhaps some contact has oxidized and because of this the system does not receive proper power.
I completely forgot about the BIOS. At the time of the tests, it is desirable to remove all overclocking and generally reset the default settings. You can read about BIOS setup.
If it does not help, then it is desirable.
According to some unverified sources, they are the causes of 70% of blue screens of death.
If it does not help, then go to the website of the equipment manufacturer and download the latest driver, remove the old one. And install a new one.
You can simply uninstall the driver in the Device Manager. Select a suspicious device. Right click on it and select Properties. On .
If there are no fresh drivers, install an older version. If nothing helps here, then check the compatibility of the equipment with your Windows. If there is no compatibility, then either change the equipment, or.
Drivers that in most cases cause the blue screen of death - .
With programs as well as with drivers. First you need to reinstall the existing one. Then go to the developer's website and download the latest version. If there are no recent versions, try an older one.
An excellent program for removing other programs with all the giblets is.
Also, one of the possible causes of critical errors is the installation of two anti-virus solutions at once on one. This is absolutely not recommended.
This is what I will do with mine, since it also sometimes pleases me with its Windows 7 blue screens of death.
The most important! Download drivers, programs and other things from official sites! This will greatly increase the survivability of your system.
A few more links so as not to lose them yourself.
The blue screen of death is familiar to every user of operating systems of the Windows family. For some users, it appears so often that they begin to think that this is a normal phenomenon. But it's not. Let's understand what the blue screen of death is. This is an error that appears when booting up or after a sudden shutdown of the computer. It indicates the presence of problems with the operating system or internal hardware. Only by understanding the causes of occurrence, you can eliminate it as efficiently as possible.
If a blue screen of death appears on a computer with Windows 7, then we bring to your attention this article, it will definitely help you find and fix this problem.
The causes of the blue screen can be divided into two main groups:
In order to accurately determine the cause of the error, you must carefully examine the contents of the blue screen. After all, it is on it that all the information the user needs is indicated, namely: the cause of the error and even recommendations for its elimination.
If the information that is indicated on the screen is not enough, then the computer can be configured specifically to diagnose the blue screen of death.
File corruption win32k sys causes a blue screen. Therefore, it is definitely worth checking and scanning other directories.
The Windows blue screen or memory dump is a reflection of the working (or not quite) state of the operating system at a certain period of time. Since immediately after the appearance of a critical error, after which a sharp shutdown of the device may follow, Windows displays all the necessary information on the famous blue screen, then for further diagnostics you just need to remember it: rewrite it or take a picture.
The main trouble is that the blue screen is shown for a strictly limited time. After that, the reboot mechanism starts. Therefore, it can be difficult for an unprepared user who does not know where to look to have time to rewrite the necessary information.
To disable auto-reboot of the device, that is, when the computer or laptop immediately starts to reboot, immediately after the blue screen of death appears, you need to activate the recording of small memory dumps, that is, part of its important content. To do this, you need to do the following:
Now the blue screen of death when loading Windows 7 will not immediately disappear, so you will have time to rewrite the necessary information.
Since any problem can cause a blue screen of death, in order to fix the error, it is necessary to identify it.
As soon as you managed to take a picture of the blue screen when loading Windows or write down the information that appears on it, you can begin to decipher the error that caused it:
Knowing this information, it becomes clear how to remove the blue screen of death.
Problems with a blue screen in 90% of cases are of the most banal nature and appear among users who are poorly versed in computers, so they often neglect to install system updates, drivers, the correct procedure for uninstalling programs, and so on.
Corrupt acpi sys file can cause a blue screen, so in order to fix the error, you need to replace it with a working one.
Even if the screen says that the error was caused by files like tcpip, ntoskrnl, fltmgr, netio, ntkrnlpa, the first thing to do is:
It will not be superfluous to defragment, check and clean the registry. It is best to do this with the help of special software. One of these programs is .
With its help, it is also possible to check the availability of all the files and libraries necessary for the stable operation of the operating system. If some of them are missing or damaged, the program will offer to download and replace them. If desired, you can make a copy of the original files and save it in any convenient place on your hard drive.
If you do not know how to remove the blue screen of death when installing Windows 7, then carefully read the following information. This error can only occur in three cases if:
If during the installation of Windows XP the blue screen repeats again and again, but you are sure that the computer hardware is in order, then the problem most likely lies in the very faulty image of the operating system that you are using.
A blue screen when installing or restoring Windows may occur due to a faulty internal drive (HDD) or incorrect formatting. Do not neglect the standard procedure for checking the health of the used OS image, disk or flash drive. All this information can be found on the screen. Correct other problems in the same way.
If you do not know how to remove the blue screen of death that occurs due to missing or corrupted system files or libraries such as TCPIP.SYS, SPCMDCON.SYS, IGDPMD64.SYS, fltmgr, DXGKRNLl.SYS, NTKRNLPA.EXE, NETIO.SYS or error 0x00000116 then this method is for you. It is also suitable for errors caused by other files with the extension .SYS, .DLL, .EXE. To do this, you can use a special third-party distributed shareware utility. One of the most popular is .
After installing the program, you need to run it and start scanning using the Start button. Next, the utility will offer to scan files like ntoskrnl, dxgkrnl, igdpmd64, fltmgr, tcpip, netio, ntkrnlpa. Additionally, the program will check other directories. If you are sure that it was the nvlddmkm sys file that caused the blue screen of Windows 7 or any other whose name you must know for sure, then you can check it.
Once the scan is completed, it will prompt:
Optionally, you can install other applications to automatically search for corrupted system files and replace them. Some of them similarly identify and fix driver-related problems.
If you have recently made BIOS changes or tried to overclock the processor, then it is possible that the problem is caused by this. Therefore, you should definitely try to return its default settings. You can do this in several ways:
And this article was considered: what is the blue screen of death, its causes. A decoding of the errors was given, and various options for eliminating the breakdowns that occurred were proposed. Now, if you get the Windows 7 death screen again, then you already know what to do.
"Blue Screen of Death" (Blue Screen of Death, Blue Screen of Doom, BSoD)- a message about a critical Windows system error, as a result of which the OS (operating system) cannot continue to work and goes into a forced restart without saving data.
Preparation for blue screen (BSOD)
The "Blue Screen of Death" (BSOD) can be caused due to a malfunction of any hardware or software failure (most often some kind of driver) Blue screen errors are displayed on a screen with a blue background, on which it is written about the possible causes of a general system failure. Therefore, the most important task is to extract from this message the lines after the second or third paragraph, written in capital letters through an underscore:
"PAGE_FAULT_IN_NONPAGED_AREA" and lines after Technical information: that start with:
### STOP: 0x00000050 (0x8872A990, 0x00000001, 0x804F35D7, 0x00000000)
### SPCMDCON.sys - (Address FBFE7617 base at FBFE5000, Date Stamp 3d6dd67c)
An equally important task is to save a dump file that contains a blue screen error (BSOD) error report. By default, it is enabled in both Windows Xp and Windows Seven (7), but if you have it disabled then:
1). If OS Windows7: Right-click on "My Computer" -> Properties -> Advanced system settings -> "Advanced" tab -> After the lines "Start and restore" click on "Settings" ->
2). If the operating system is Windows XP: Right-click on "My Computer" -> Properties -> "Advanced" tab -> After the lines "Start and restore" click on "Settings" -> check the box "Log event to the system log" and uncheck "Perform automatic restart".
The next time the blue screen appears, the computer will not restart automatically, and secondly, it will save a dump file that will store information about the BSOD.
We determine the cause of its occurrence from the BIOS blue screen.
Then, turn on the computer and try to load Windows.
If, when Windows boots, it immediately “knocks out” a blue screen, then on the next reboot, we boot into “safe mode”, only select not safe mode, but “Disable automatic reboot on system failure”.
Write down the lines on a piece of paper that will be needed for the next steps.
In our case, the system file "SPCMDCON.sys" is to blame. Therefore, the first step is to either delete it or, on the contrary, restore it (in your case, some other file will be indicated that causes the causes of the Windows system failure). To do this, boot from a bootable Live Cd or bootable Live USD and delete this file manually (or restore it if you deleted it before the blue screen).
We search through Live for the "Boot Disk" on the disk with Windows SPCMDCON.sys and rename it, for example, to SPCMDCON(2).sys.
If not, we continue to deal with the blue screen in exactly the same way until we defeat it!
If the Blue Screen of Death (BSOD) does not immediately "knock out" and Windows is loaded normally, then we read the Dump file. To do this, download from the Internet (Google - to help!) BlueScreenView and run BlueScreenView.exe.
Identified system errors should be removed manually and only then installed newer ones (often causes a blue screen - freshly installed video card drivers).
What should I do if the Blue Screen of Windiws problems occurs during games or after a different period of time (reinstalling Windows does not help)?
If such a situation arose and you have already used all the possibilities (described above) and even after completely formatting the hard drive and reinstalling Windows "to a clean one", and the Blue Screen does not go away, then this means that the problem arose not due to the software and due to some kind of hardware problem. Here tests of the processor, random access memory can help you. This problem may also arise due to the installation of a new video card (it may very well be that the power supply of your computer is not designed for such loads), or the cause of all the troubles lies in a faulty RAM strip, or the capacitors "swollen" or leaked on the motherboard. .. If you are no longer able to independently diagnose the cause of malfunctions, our advice is to go to a computer repair service, they will definitely help you there!
Here is a list of the most common blue screen errors (BSODs):
(The most common blue screen of death (BSOD) errors are taken from the official Microsoft website)
- A kernel-mode process attempted to execute an invalid or unknown processor instruction. May be due to hardware incompatibility, hardware failure, driver or system service errors.
- Crash while executing ntfs.sys file system driver code. The reason may be a violation of the integrity of the data on the disk (bad cluster) or in memory, damage to the IDE or SCSI drivers.
- A parity error has been detected in the RAM. The reason is defective or incompatible hardware, for example, a failure in the second-level cache chip, in the video memory. It can also be related to a malfunctioning or misconfigured driver, or a disk failure.
- A kernel-mode process attempted to access a region of memory using an unacceptably high IRQL (Interrupt Request Level) for it. May be caused by errors in a driver, system service, BIOS, or an incompatible driver, service, software (such as antivirus).
- the requested data is not in memory (for example, the system looks for the necessary data in the paging file, but does not find it). Usually associated with a hardware failure (defective memory), file system corruption, system service or antivirus error.
- Unable to read the requested memory page from the paging file into physical memory. Causes - defective sector of the virtual memory file, hard disk controller failure, insufficient disk space, incorrect hard disk connection, interrupt conflict, defective RAM, virus.
- the hardware abstraction level (HAL) and the system kernel do not match the type of computer. Most often associated with a situation where a second processor is installed in an initially single-processor system, forgetting to manually update HAL and ntoskrnl. May also be caused by version mismatch between hal.dll and ntoskrnl.exe.
- Unable to read the requested data page into physical memory. Causes - defective sector of the virtual memory file, hard disk controller failure, RAM failure, virus, disk controller failure, defective RAM.
- during the boot process, the OS could not access the system partition. There can be many reasons for this common failure: a defective boot disk or disk controller; equipment incompatibility; boot virus; an error in the file system, for example - in the Partition Table; damage or absence of a file necessary for loading, for example - NTLDR; the lack of a hard disk controller driver or the current driver does not match the installed equipment; DMA mode enabled in BIOS; DRIVE SWAPPING mode enabled in CMOS Setup; resource allocation conflict between the disk controller and another device; damage to data about loaded drivers in the system registry; installation of the system in a partition outside the first 1024 cylinders of the hard disk; error in boot.ini file.
- the occurrence of a trap not supported by the kernel (trap) or a fatal error (such as division by zero). Hardware failure or software failure.
- Crash in a service running in user mode. The failure may be due to incorrect operation of application programs, drivers, third-party system services.
- damaged or lost driver or system library file. May be caused by a file system crash or accidental deletion of a system file.
