Error codes bsod. Why does the "Blue Screen of Death" appear, how to remove it and what the error codes mean

BSOD (English... Blue Screen Of Death)

BSOD- this is the name of the message that appears in the operating room Windows system , in case of a critical system error, translated into Russian - blue screen of death. This screen appeared in Windows NT and, since then, has been present in all versions of this operating system, and it is called so ominously because after its appearance the OS really "dies" (goes into a reboot), dumping the dump and losing all unsaved data.

What causes BSOD? This error is waiting for you if any the driver will try to perform an illegal operation, and it doesn't matter if it is a driver hard disk, without which it is really impossible to work, or a network / sound card driver, which does not affect the operation of the main functionality of the system ... the result is the same: BSOD and an emergency reboot.

Driver problems causing blue screen death, can be conditionally divided into two types:

hardware problems (RAM, motherboard, hard drive, non-standard devices ...),
driver conflict software(antiviruses, emulators, firewalls ...).

There is an indirect sign by which you can determine the cause of the BSOD.

If a blue screen appears with different codes errors (on random drivers) - most likely the cause is computer hardware problems. To check this version, you must first examine the equipment for possible overheating: processor, coprocessor, video card, hard disk, etc. The temperature of devices can be viewed in the BIOS or specialized programs that are easy to find on the network. Temperatures above 65-70 ° C are cause for concern.
If overheating is not observed, it is worth visually inspecting the motherboard and power supply for swollen capacitors (leaked electrolyte).
You also need to check BIOS settings, it is advisable to reset them to their default settings. It will not be superfluous to update the BIOS version from the motherboard manufacturer's website, or at least remove the battery from the motherboard and, after waiting about a minute, insert it back.
Try to conduct various tests on a computer (memory, video card, processor) with special utilities.
If you have several modules installed on your computer random access memory, try leaving one of them and check the system operation.
The last method of checking is to completely remove all the boards from the connectors, blow out the computer with compressed air, clean the contacts on the boards with cotton wool dipped in an alcohol solution, dry them and put everything back together.

If a critical error occurs constantly with the same error code (driver name), then the problem is more likely with a driver conflict or an incorrectly written driver. In this case, the priority of the check should be given not system drivers, a software drivers, running in kernel mode.
The first thing to do is to make sure that your operating system stores areas of memory with errors in minidump files. On Windows, such files are saved by default in the% systemroot% \ Minidump folder (C: \ Windows \ Minidump). If there are no files in this directory (there is no directory itself), you must enable this option at the address:
For Windows XP Control Panel - System - Advanced - Startup and Recovery - Options ...
For Windows 7 Control Panel - System and Security - System - Extra options Systems - Boot and Recovery - Options ...
Under the heading "Recording debug information" you must set Small memory dump(64 KB for Windows XP, 256 KB for Windows 7).

After that, minidump files will appear in the default folder after every system crash. The file names will indicate the date of saving and the ordinal number of the saved file for this date. You can open such files special programs, which are easy to find on the Internet by search query... By opening the minidump file for the date you are interested in, you can see which driver caused the abnormal termination, after which you can roll back / update this driver, reinstall conflicting software, and take other actions to restore the computer's performance.
Blue screen of death – this is a critical error message from the operating system. So Windows way makes us understand that there are serious problems with the computer that require the immediate attention of the user. Let's try to figure out what can cause the blue screen of death, how you can prevent its appearance and how you can deal with it.

What is the Blue Screen of Death?
In order to identify the causes of the appearance of the blue screen of death, it is necessary to understand what it is. Blue Screen of Death or BSoD- exactly given type errors are called by the Windows developers themselves. Blue - because the message from the system is displayed on a blue background. Death screen - since further Windows work after such an error is impossible, it is necessary to reboot the operating system, and all unsaved data will be lost. If you see BSoD on your computer 1 or 2 times - do not worry, occasionally everyone has operating system crashes. If the appearance of the blue screen of death has become regular, it is worth thinking about the reasons for its occurrence and how to eliminate it.

Blue screen of death, possible reasons its occurrence.

The main causes of the blue screen of death are:

A software failure in the operation of a device driver. This is the most common cause of BSoD.
A conflict in the operation of applications, as a rule, this happens if you have installed two anti-virus packages or two firewalls on your computer.
Installing drivers from an unknown developer - often drivers from third party developers may contain errors leading to interruptions in the operation of the operating system.
Errors in the operation of equipment - overheating of the processor or video card, poor contact in the connectors, defective RAM chips.

As you can see, the list of reasons for the appearance BSoD quite extensive. In order to find out the specific reason, we should take a close look at the blue screen of death itself in Windows XP or another Windows versions... In the Technical Information block, the first line is the error code. It will be difficult for a non-specialist to understand what is hidden behind this sequence of numbers; in the second line of this block, the system tells us exactly in which file a critical failure occurred, which led to the appearance of the blue screen of death. By the name of the file, you can determine in the driver of which particular device an error occurred.

How to deal with the blue screen of death.

At the previous stage, we analyzed the causes of BSoD... Now, based on this data, we will determine why on our computer appeared blue screen of death and what to do in order to eliminate the source of the critical error.

First of all, you need to find out which device driver is the file in which the failure occurred. After that, you need to reinstall this driver, be sure to use the software from the device manufacturer. Now reboot the system and let it run if the error reappears - other reasons for the system crash should be considered. The Blue Screen of Death in Windows 7 often occurs due to hardware malfunction. Try to check, with the computer disconnected from the network, the reliability of the installation in the corresponding connectors on motherboard RAM and video card. Often it is a poor-quality installation or the presence of dust on the contacts that can lead to system malfunction.

The most common BSoD. Blue screen of death error codes

KMODE_EXCEPTION_NOT_HANDLED- Causes a blue screen as a result of a kernel-mode process error trying to execute an unknown instruction. May be due to hardware incompatibility or malfunction, or errors in drivers or system services.

NTFS_FILE_SYSTEM- this error appears as a result of a failure to execute the code of the ntfs.sys file system driver. The root cause may be data integrity on disk or memory, or damaged SCSI or IDE drivers.

DATA_BUS_ERROR- the blue screen of death appears as a result of the appearance of a parity error in RAM. The main reason may lie in incompatible or faulty hardware. Also, the problem may be associated with an incorrect driver, as well as a failure that has passed on the disk.

IRQL_NOT_LESS_OR_EQUAL- the blue screen of death in this case appears as a result of the kernel mode process accessing the memory area while using an unacceptably high IRQL level for it. This error may be caused by improper operation of drivers, system services, or incompatible software such as an emulator or antivirus application.

PAGE_FAULT_IN_NONPAGED_AREA- the error appears as a result of the system not finding the necessary data, for example, when Windows searches for the necessary information in the paging file, but cannot find it. Often, the appearance of a blue screen of death in this case is caused by hardware failures, disruptions in the operation of file systems, or an error in a service or software, such as antivirus.

KERNEL_STACK_INPAGE_ERROR- This error appears as a result of reading errors from the paging file into physical memory. The main reason for the appearance of the blue screen of death is a corrupted sector of the virtual memory file, incorrect operation or malfunction of the controller hard drives, insufficient amount of free disk space, incorrect connection of the hard drive, a conflict in interrupts, a defect in RAM, viruses in the operating system.

Basically, the appearance of the blue screen of "death" is caused by: software (drivers), sometimes in the hardware (its failure, conflicts or malfunctioning). In these cases, when a blue screen of "death" appears, you need to delete recently installed programs and drivers, and disable and remove recently installed hardware.

You need to uninstall the software in Safe Mode Windows. To do this, when loading the operating system, you must press the F8 key and select Safe Mode.

A common cause of the blue screen of death is overheating of the hardware (computer components). In this regard, the protection is triggered, which is the reason for the emergence of BSoD. To do this, you need to remove the cover of the system unit and determine the source of overheating - very often this source is CPU, less often a video card and a power supply. If a malfunction is detected, it (malfunction) must be eliminated, then the BSoD problem will be eliminated.

It looks like the title of the Harry Potter book, but you won't find Hogwarts narration in this opus. If you are reading this article, then your computer has comprehended a mysterious error message, in narrow circles called BSOD and how to remove the blue screen of death you will learn from this article. As scary as it sounds, there is nothing wrong with that. BSOD is a Windows OC STOP message that literally means that the system has been stopped for unforeseen reasons. Errors of this kind appear only in operating systems of the NT family: Windows NT, Windows 2000, Windows XP, Vista and Windows 7.8. Most hardware problems are identified by an 8-digit hexadecimal code, but can also be written in short form; for example, the error code 0x0000000A can also be written as 0xA. The four additional 8-digit numbers in parentheses may appear depending on your computer and your situation.

If in this article you come across a STOP message for which there is no explanation (only the number and name), most likely this type of BSOD is extremely rare and, as a rule, can only interest programmers. V real life an ordinary computer user is unlikely to be able to meet with such a "blue screen", so I decided not to describe these errors here, but nevertheless, if someone comes across such a BSOD, write in the comments or in my personal - I will add the article.

If you have searched the entire Internet and cannot fix the problem, the list of solutions presented below will help you. This list will also assist in the elimination of some specific STOP messages such as 0x0A.

V command line type the eventvwr command, then analyze the events of the “System” and “Application” tabs. Perhaps there will be additional information to eliminate your misfortune.

Run the manufacturer's hardware diagnostic program.

Make sure device drivers and BIOS are up to date.

If you installed new drivers just before the problem appeared, try rolling them back.

Open up system unit and make sure all hardware is installed correctly, nothing has come off, and everything is securely connected.

Make sure all of your hardware is on the HCL. If this is not the case for some components, then pay special attention to the incompatible hardware code.

Check recently installed software.

Disable memory caching in BIOS.

NOTE: When the Blue Screen of Death appears, Windows creates a file with detailed error information. For this purpose, the operating system needs a work area equal to the amount of physical RAM. If you make the size of the paging file less than the size of physical memory, an informational message will appear stating that your system is not able to create a file with debug information in the event of a BSOD.

BSoD or Blue Screen of Death in Windows can appear for various reasons. Starting from a crash in a separate program, ending with the breakdown of important equipment. If you've only seen BSoD once, it's too early to sound the alarm. But if the failure is regular, then there is some problem 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 need to restart your PC right away. Check the error code. From it you will understand what is “broken”. And you can eliminate the cause of the failure.

When BSoD appears, pay attention to the sections:

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

Reasons for the error

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

Here's what causes the crash:

Hardware malfunctions. The hard disk, RAM, LAN card, video adapter;

The problem may be caused by a defective hard drive.

An incompatible device or equipment is connected. Let's say you decide to install new RAM cards or connect an external hard drive. And after that Windows started crashing into BSoD;
Conflict of software, in particular, drivers;
BIOS crashes or bad firmware;
Overheat;
Updating Windows or individual services. Along with this, you can download a huge number of errors. Even licensed programs are not insured against them. If BSoD appears after a system update, just roll it back. And wait for the update to be fixed and optimized;
Contact between wires and internal equipment. For example, the cable got caught in the fan blades;
that damaged important files;

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

Error codes

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

"0x0000000X", where "X" ("X") are numbers from 1 to 5. Actual for Windows Server 2003 and Win XP with SP. Appears when installing some antiviruses. To fix everything, download the update "KB887742" from the Update Center or from the official Microsoft website;
"0x0000000A" and "0x0000000X", where "X" is equal to numbers from 6 to 9. The driver is damaged. Or there are incompatible software / hardware;
"0x0000000X", where "X" can be numbers from 13 to 19. The codes mean that there is no communication with the memory card. Or the connection to the hard drive, which contains the swap partition, is lost;
"0x0000001F" and "0x0000000X", where "X" are numbers from 20 to 23. An error occurred while reading / writing information. Appears on FAT file systems. The reason may be a hard disk breakdown or severe data fragmentation. A "blue screen of death" with this code also occurs due to incompatible antiviruses and firewalls;
"0x00000024". The same, but for the NTFS file system;
"0x0000000X", where "X" are numbers from 28 to 35. Problem with drivers or RAM;
"0x0000000B", "0x0000000C", "0x0000000D". Related to software crashes for sound card Sound Blaster Live;
"0x00000051". Occurs when the system cannot read some registry entry. This happens when the system or hardware is damaged;
"0x00000057". There is something wrong with the network card;

Death screen example

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

The list is long enough. It has hundreds of different numbers. You can enter the error code in a search engine to find out detailed information... Or see it on the site "bsodstop.ru" (tab "BSoD: error description"). There are also instructions on 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 important data as soon as possible. If they find themselves in a damaged sector, it will be difficult to restore them.

View code if system reboots

How to find out the crash number if the computer restarts when BSoD appears? And you just don't have time to read the message.

You can see the blue screen codes in the 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 crash will be marked in red.

How to fix the error

Equipment broke down

If the equipment breaks down, 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. Let's say it became clear from the error codes that there is no access to RAM. Here's what to do:

Turn off the power to the computer. Do not just press the "Off" button, but unplug the plug from the socket;
Open the lid of the system unit;
Find RAM boards there;

Pull them carefully out of the slot. It is necessary to pull back the latch that holds them;
Insert them back;
Turn on your computer and check if everything works.

The same can be done with hard disk, and with a video adapter and a sound card. But if you are unfamiliar with the internal structure of a computer, it is better to entrust it to professionals. Do not take out all the details from the system unit one by one.

If it does not help, then the equipment has become unusable. It needs to be changed.

Disconnecting external devices

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

Perhaps it's not the computer, but the port controller. If it is faulty, it must be disabled.

Problems with the file system or hard drive

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

Click on it right click mice;
Item "Properties";

Go to "Properties"

Service tab;
Check button;

Click on "Check"

Check all the boxes. In particular, the option "Recover bad sectors" is needed;

We put a tick next to "Recover damaged sectors"

Start button;
The service will warn you that it will start checking the next time the system is started;
Reboot your computer;
It will start rebuilding the disk. This can take a long time. Do not interrupt the process.

Software glitch

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

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

In the window that opens, check the "Select a restore point" item;
If necessary, check the box "Show all restore points";
They show the time when the backup copy, and what happened at the same time (installation, removal, update);

Recovery points

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

The system will rollback. It will return to the state it was in before the errors occurred.

Other options

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

CCleaner program

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

If Blue Screen Appears at Startup

If the "Blue Screen of Death" appears immediately after turning on the computer, you will not get 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. Also works free program from DrWeb - "Live Disk". It can be downloaded from freedrweb.com:

When starting the PC (at the very first "frame"), a key will be indicated, which must be pressed to open the settings ("PRESS TO ENTER SETUP"). Typically F1, F2, F5, or Del;
Click on it. BIOS options will open. In them, all control is tied to the keyboard;
Go to the "Boot" tab;
Item "Boot Device Priority";
There will be a loading order. Put in the first place the device from which you plan to download data (disk or drive);
Open the "Save" section, select the "Save and reset" option;
Now the computer will start from external media (don't forget to insert it);
If this boot disk or CD with Win distributions, try reinstalling them;
