Why a blue screen appears on Windows 7. Blue Death Screen (BSOD) - We are struggling with errors

Friends, I prepared for you an article about how in some cases in practice, remove the blue screen of Windows BSOD (or how professionals are also called - blue death). The blue screen occurs in the case of a critical error in which the further work of Windows is impossible! What to do when the blue screen appears how to decrypt the error code how to help your friends if they have the same problem, in our article.

Blue Windows screen

Letter. To you, the question is Dear Admin, I can not remove the blue screen on the computer. Safe mode is not available, there is the same blue screen. I asked a question on one of the forums on the Internet, I ask the blue screen error code. I say I can not read the error code, the blue screen appears for a second and the computer again goes to the reboot, and they me - well, then we do not know.
On another forum they say that I have a conflict of drivers, you advise you to update or reinstall problem drivers. First, how can I find out exactly what kind of driver is to blame in the appearance of a blue screen, if I can not go to the system.
On the third forum I went, I ask a blue screen for me, what to do dear? I answer, download the computer from any Live CD, then remove your files from the disk (C :) and reinstall the system. I answer them - this is the fact that it does not work. Loading your computer with Live CD, and there is a disk (C :) is simply not. And you know what they answered me - this does not happen.
Called the wizard, he said the file system on the disk (C :), which means that new formatting and reinstalling. And in general when blue screen Windows The best output one, the installation of the system is anew and naturally loss of data from the system partition (C :), the second partition of the hard disk (D :) will not be affected by reinstalling the operating system. I already agree on reinstalling, I have all the important files and folders on (D :), but I need to at least pull out my photos and documents from the disk (C :), on the desktop with: \\ Documents and Settings \\ Name User \\ desktop. Is it possible? Alexander.
Administrator note: Quite often, file system errors can be corrected even when the operating system is not loaded, read the article "".

Error kernel_data_inpage_error or Stop: 0x0000007A (0xc0519750, 0xc000000E, 0x0f6b9be0, 0xa32ea000) caused by an error of the hard disk controller or the inability to read the data due to the damaged block on the Winchester itself, how to solve the problem, read at the end of the article!

(This blue screen, indicates the error of the compiled HDAUDBUS.SYS file, responsible for the sound)

There are few ways to help you, but they are. Friends, I advise you to read the whole article, as this topic is very serious. Everyone will be disassembled on specific examples that took place in life. I want to say that even the experienced PC users often do not always have successfully establish the cause of the blue screen and even reinstalling the system does not always help solve the problem. Blue screen appears again. Numerous forums dedicated to the blue screen of Windows are evidenced by numerous forums, where the cause of the blue screen, many managed to establish with great difficulty.
In fact, the author of the letter that came to us on the mail is damaged file system or many errors appeared on the hard disk, it happens in most cases from the incorrect shutdown of the computer, it hovels with us a little and we have rebooted it via the RESET button or at all turned off. Of course, problems are possible and with the disconnection of electricity in your home. One of the results of all the above will be a blue screen with an error 0x000000E3 or an error code 0x00000024 NTFS_FILE_SYSTEM name, which indicates problems with the file system and hard disk.

Information about how we solved the problem of the blue screen of our reader and some more similar problems at the end of the article, but first we will analyze because of what the blue screen occurs, how to decrypt the error code of the blue screen and how to act if error code to decrypt at all.

Blue screen, instead of the desktop, when booting Windows, denotes a critical error in the operating system at which further work is impossible. Even if the blue screen appears with you when you boot the system at times, it's still a reason for finding a possible error.

The most common reasons for the appearance of the blue screen of Windows:

Of course, to solve the problem of the blue screen, we have on a computer, very good to learn at first the reason for its appearance. To do this, the operating system displays us the appropriate information on the blue screen, which is mostly the same, except for two small error code and error code.
How to decrypt the blue screen error. Let's look through two cases that you can be.

Blue screen appears when booting a computer and remains on the screen for a long time, giving us the opportunity to read the name and error code.
The blue screen appears when the computer is booting for a second and disappears, the computer again goes back to the reboot, respectively, we do not have time to read anything (about this complex version below).

Relying in solving the problem of the blue screen, it is impossible to decipher the error codes. The same error for example is 0x0000008e, may designate a malfunction of RAM and at the same time with rootkit, and the other error 0x0000000a IRQL_NOT_LESS_OR_EQUAL may not be denoted by dozens of reasons. But also to reinstall Windows immediately, in the event of a blue screen, it is also not worth it, you still need to try to figure out what the case is ...

In case of a critical error, your computer will not constantly reboot and you could read the error code on the blue screen, the first thing you need to try is when you turn on the computer on the keyboard the F-8 key and get into the optional download options, then select paragraph Disable automatic reboot when system fails,

if it does not help, then you will not be superfluous to know such information. I want to say that the operating system is able to save the blue screen error information in a special file, which is called - a memory dump, it will be in the folder C: \\ Windows \\ minidump. But for this you need to enable writing debug information. Do it right now.
In Windows XP:
Right-click on my computer, then the properties-\u003e additionally-\u003e Download and restore parameters-\u003e System failure-\u003e Turn off the option. Select a small memory dump (64 KB) and click OK.

For Windows 7:
Starting -\u003e Control Panel -\u003e System and Security -\u003e System -\u003e Advanced System Settings -\u003e Advanced Tab "-\u003e Loading and Restoring-\u003e Options Remove the checkbox to automatically reboot. Select a small memory dump (128 KB) and click OK.

Let's now turn to specific examples (which in fact I had to solve) eliminate the problem of the blue screen.
So the first option. The debug information entry is included. On the computer, after installing the latest game, sounded sound, after updating audio drivers, the computer went to reboot and dumped the blue screen with such an error. We write out the name and error code, the decoding of almost all error codes is shown on the site http://bsod.oszone.net/. Information about your error code, you can also search the Internet, through any search engine. For anyone, she has already come across and applies to it some decision.
In our case, the system compiled HDAUDBUS.SYS file is directly indicated in the error name. It belongs to the Microsoft UAA BUS Driver for High Definition Audio, a big percentage that our blue screen is due to the problems with the audio system driver. Error code:
Stop: 0x00000101 (0x00000031, 0x00000000, 0x807c9120, 0x00000001)

In this case, you can try to reinstall the drivers on the sound card. And what if there is no defective file on the blue screen. In this case, on ozone, you can download the BlueScreenView utility - to more accurately determine the driver or file that caused the blue Windows BSOD screen. How to use the BlueScreenView program I will now tell. The program is very simple, run BlueScreenView and it immediately scans the folder on the subject of the memory dump file, which will remind you at C: \\ Windows \\ miniDUMP and looks like this:

Select the left mouse of the memory dump in the top window of our program and immediately look at the bottom window, the error information will be sure to appear there.

By the way, if you press F-8 when the program is running, our blue screen will appear in the bottom window.

Microsoft has its own debugging tool for Windows Debugging Tools, link

http://www.microsoft.com/whdc/devtools/debugging/default.mspx

but I would say the BlueScreenView utility, it works easier, and the result is not worse.
You can ask, the computer does not load us, how to reinstall the audio drivers? First, you need to try to roll back at a certain time period, using the system recovery points, this can be done in safe mode or in the Windows 7 troubleshooting menu (when loading F-8) or from a seven recovery disk. To delete a problem driver, in the case of a blue screen, you can try to enter a secure mode with command prompt support and dial the DevmGMT.msc command and you will fall into the Device Manager.

After removing the problem driver, you need to install updated versions of the drivers, preferably from the official sites of device manufacturers. Or, on the contrary, install an old and stable driver.

Now go to a more difficult issue. What if the blue screen appears for a second and read the name and error code is not possible?

Know if you deal with a stranger computer, often the error code cannot be seen, the blue screen will appear for a second when the computer is turned on and disappear. Since not everyone is ticking in the Options to turn off the automatic reboot when the system fails. Now you know what to do, so that the blue screen remains on the monitor and the computer did not leave immediately in reboot, you could read it higher.

With this situation, do not hesitate to ask in various forums, but also remember particular cases. If you even know the error code, but it is impossible to correct the situation, just talk to people, ask what programs or drivers were installed last, before the appearance of a blue screen. What recent actions were conducted with a computer.
What else can you do if your Windows show you a blue screen? Let's take the interesting case of our reader, the more I had to very often solve a similar problem.

Real examples of the removal of the blue screen in the Windows XP and Windows 7 operating system.

We broke our computer at work, the Windows 7 system regularly reboots, the blue screen, appears for a second, do not read the error, although it should not be so a tick in the point Perform an automatic reboot (See higher information), I cleaned. There are many important data on the computer, they all appeared on the computer during the last few hours and everything on the disk (C :), on the desktop, everything must be achieved by anything, and then you can engage in restoring system performance, for example, just restore Her backup, which was made last night, but this, if nothing helps.
The first thing I do, I am trying to go in, I'm loading when loading F-8, I think I will try to restore the start, and maybe with the help of the recovery point back to drop, but also a safe mode with the command line support, as well as (can the video card faulty) to no avail. Opened the Socketer, everything is not purely dust, changed the RAM, then the video card did not help. I think let me upload a computer with (I always have two disks 32-bit and 64 bits), it may be possible to get to the system recovery.
Well, I boot with sin in half from Windows 7 recovery disk, and not a single system to find

"In a nutshell", the blue screen appears at the time of the occurrence of the error (error of the operating system core) at which the system can no longer continue its work. The problem is characteristic of any failures - from software incompatibility until the temperature of the processor is exceeded. To, more or less, to accurately determine the cause of the failure, the analysis is necessary on the basis of the text and the code of the error itself. Desktop computer or laptop - no matter, the approach to solving problems is the same.

Disable automatic reboot

Analysis of the problem by code

Having received the code, we will be able to find information from the description of the cause of the problem and how to solve it.

Getting code in Windows 8 and newer

More modern codes have less than a description and technical information, and the code itself is presented with a sad emoticon and a text description, for example, clock_watchdog_timeout:

also, in addition to the error (sometimes, without inscriptions and text), the QR code may be present:

Codes in windows 7 and older

When the blue screen appears, you need to find an error code. It has a view of 0x0000 ..., for example, 0x0000008d:

* Codes in brackets are additional parameters and serve to clarify the error localization. They can be individual and, as a rule, are not taken into account with further analysis.

Analysis online

Now open sites with error codes, for example:

You can also enter the error code directly to Google or Yandex search string. And if there is a QR code, you can consider it a reader and go to the description of the problem.

Solving the problem, you must carefully read about the causes of the failure and make recommendations.

Analysis of dumps

In the case when an automatic reboot is enabled or we analyze the problem later, you can use the dump - a special file that contains information about the last state of the system before an error with all the necessary descriptions and codes.

By default, this file is on the path% Systemroot% \\ Memory.dmp (as a rule, this is C: \\ Windows \\ Memory.dmp). You can see or change the path in the same place where the automatic restart is turned off - right-click on This computer - Properties - Additional system parameters -

You can read a dump with a special utility, for example, BlueScreenView. You can download it on the official website.

After starting the utility, we must see (if there were problems) a list of stop errors with codes, reports and additional information:

Having received the error code, we carry out the analysis using search engines or specialized sites by the method.

Top error codes

0x00000109. The overall error caused by the incorrect operation of RAM or disk carrier. Sometimes, due to the virus.
0x00000050. Problem with device driver or incorrect hardware.
0x0000007B. It is necessary to check the media and the order of loading the system in the BIOS.
0x0000007E. General code that combines a large number of different problems. Read below on the article on typical problems and methods of their solution.
0x00000012. The system failed to understand the cause of the failure. To solve, also use the text below.

Typical reasons that lead to the appearance of errors and methods to eliminate them

Consider the top problems due to which the error of the operating system core appears, as well as the methods of their solution:

Problem with device driver. If the error appears after installing the new driver or its update, you must roll back the driver to the previous version.
Unsuccessful Windows Update. It happens, as a rule, when setting a large number of updates or installation of a poor-quality patch. Solved by rollback of installed packages.
Incorrect operation of equipment. To find out, it is necessary to conduct a stress test program AIDA64 or analogs. It is also necessary to test the RAM and the operation of the disk carrier.
Reset BIOS settings. When changing the drive mode (AHCI, IDE, RAID), the system will stop loading, issuing the stop error. The parameter can be stamped due to the BIOS Sorted Battery or manual reset.
Viruses. They can write off many problems. But check the computer is worth it, for example, the Cureit program.
Incompatible software. If installing or updating any programs has led to a problem, reinstall the software product or install the previous version.
Violation of the license agreement. In some cases, the blue screen can appear every hour - two. As a rule, this is due to the fact that not activated Windows is used.
Problem in the video card or overheating. As a rule, it is observed in games or when watching a video. To diagnose, you need to update the driver and conduct a stress test. Also worth paying attention to the temperature of the video card.

If the system does not boot

In some cases, BSOD appears when booting Windows. This greatly complicates the diagnosis. In the case when you cannot load the system, and the blue screen appears for a moment, or does not appear at all, you need to turn off the automatic reboot when turned on.

Another option is to use the Windows LiveCD bootable, which contains a large number of utilities for diagnosing the problem.

BSOD or "Blue Death Screen" in Windows can appear for various reasons. Starting from the failure in a separate program, ending with a breakdown of important equipment. If you saw the BSOD just once, early beat the alarm. But if the failure is regular, it means that some problems with a computer. And you need to pay attention to the information that is shown in the error.

You calmly worked at the computer, and saw in Windows 7 "Blue Death Screen". What to do in this case? Do not immediately restart the PC. Look at the error code. On him, you will understand what "broke". And you can eliminate the cause of the failure.

When BSOD appears, pay attention to the sections:

"The Protem Seems to Be Caused". There is the file, due to which the failure occurs;
Just below will be the name of the error;
"Technical Information". Technical information. After the word "STOP" must be written the error number. For example, "0x0000007e" or "0xc0000135";
Next, the driver name and error address goes.

Causes of error

Recall what was before the "blue screen of death" arose. So you can figure out what to do with it. For example, you have connected a new device, installed the program, updated the system or downloaded non-license drivers for Windows. If the problems started after that, it means that you found the culprit. You can also determine the reason if you look at error codes.

This is what leads to a failure:

Hardware faults. Hard disk, RAM, network card, video adapter, may be damaged;

The cause of the problem may be a hard disk malfunction

An incompatible device or equipment is connected. Suppose you decided to put new RAM boards or attach an external hard drive. And after that, Windows began to "fly out" in BSOD;
Software conflict, in particular, drivers;
Failures in BIOS or bad firmware;
Overheat;
Windows update or individual services. At the same time, you can download a huge number of errors. Even licensed programs are not insured against them. If BSOD appeared after updating the system, just roll back it. And wait until the update fix and optimize;
Control of wires and internal equipment. For example, the cable hit the cooler blade;
which damaged important files;

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

Error codes

To understand how to get rid of the problem, you need to see the error codes. "Blue Death Screen" provides the necessary information. But the list of such numbers is huge. After all, it can break anything. And it is not clear what in this case to do. Here are the most common failures:

"0x0000000x", where "X" ("X") - numbers from 1 to 5. Actually for Windows Server 2003 and Win XP with SP Updates Pack appears when installing some antiviruses. To fix everything, download the update "KB887742" from the center of updates or from the official site of Microsoft;
"0x0000000a" and "0x0000000x", where "X" is equal to the numbers from 6 to 9. Driver is damaged. Or there are incompatible programs / equipment;
"0x0000000x", where "X" can be numbers from 13 to 19. Codes mean that there is no connection with the memory card. Or lost connection with the hard drive, on which the swap section is located;
"0x0000001F" and "0x0000000x", where "X" - numbers from 20 to 23. Error reading / writing information. Appears in FAT file systems. The reason may be a hard disk breakdown or strong data fragmentation. "Blue Death Screen" with this code also arises due to incompatible antiviruses and firewalls;
"0x00000024". The same, but for the NTFS file system;
"0x0000000x", where "X" - numbers from 28 to 35. The problem with drivers or operational memory;
"0x0000000b", "0x0000000c", "0x0000000d". Related to SOUND Blaster Live Sound Boards;
"0x00000051". It occurs if the system cannot read some registry element. This happens when the system or equipment is damaged;
"0x00000057". Something wrong with the network board;

An example of the screen of death

"0x00000069". Incorrect installation of the system or incorrect configuration;
"0x00000073". Damaged part of the registry. Or lack free memory;
"0x0000007E". May appear when updating Windows. For some reason, the update caused a failure. To eliminate it, you need to roll back the system;
"0x0000008e". Breakdown of RAM. Or RAM modules are incompatible with each other;
"0x000000Fe". Critical failure in USB controller;
"0x00000104". Problem with video adapter driver or BIOS firmware;
"0x1000007e", "0x1000008e" or "0xc000009a". Windows system kernel lacks resources for stable operation. Free the operational and local memory;
"0x80070570". The system is incorrectly installed. The problem may be in the installer itself;
"0xc0000135" and "0xc0000218". Dynamic libraries are damaged or missing. BSOD shows which object is unavailable;
"0xc0000221". Problem with driver or library;
"0xDeadDead". The user itself launched the emergency stop of the system.

The list is long enough. There are hundreds of different numbers in it. You can enter the search code in the search engine to find out detailed information. Or watch it on the site "BSODSTOP.RU" (BSOD Tab: Description of Errors »). There are also instructions in which it is described what to do in each situation.

If the same failures arise with different objects (codes coincide, and there are no file names), most likely, the problem is not in the system, but in the hard drive. Make a backup copy of important data as soon as possible. If they are in the damaged sector, it will be difficult to restore them.

View code if the system reboots

How to find out the failure number if the computer is restarted when the BSOD appears? And you just do not have time to read the message.

The "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. Lay it on the Internet, install and open. She scanned dumps and give their list. Files in which there are information about failure will be marked red.

How to fix the error

Broken equipment

If the equipment broke, it is unlikely to be able to repair at home. But sometimes it is enough to turn it off and turn on again. Suppose the error codes it became clear that there is no access to RAM. That's what to do:

Disconnect the power of the computer. Do not just click the Off button, and remove the plug from the outlet;
Open the system unit cover;
Find there RAM fees;

Gently pull them out of the nest. We must delay the latch, which holds them;
Insert them back;
Turn on the computer and check whether everything works.

The same can be done with a hard disk, and with a video adapter, and with a sound card. But if you are unfamiliar with the internal device of the computer, it is better to trust this professionals. It should not be alternately pull out all the details from the system unit.

If it did not help, it means that the equipment has become unusable. It must be changed.

Disable external devices

Very often, BSOD appears when hard drives or other external devices are connected to the computer. How to fix "Blue Death Screen" in this case? Disable equipment. Try to insert it into another port. See how it is displayed in the Device Manager. Check if there is no exclamation mark next to the title. Update drivers.

Perhaps it's not a computer, but in the port controller. If it is faulty, it must be turned off.

Problems with file system or hard drive

Run the scan and restore the system disk. For this:

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

Go to the "Properties"

Tab "Service";
"Check" button;

Click on "perform check"

Check the ticks into all items. In particular, the option "Restore damaged sectors" is needed;

We put a tick next to "restore damaged sectors"

"Run" button;
The service will warn it, which will start checking the next system launch;
Restart the computer;
It will start recovering the disc. It may take a long time. Do not interrupt the process.

Software failure

Here's how to remove the "blue screen of death", if the problem is in the system itself or installed on it:

Remove everything that was installed immediately before the failure;
If it did not help, make a backup;
Go to Start - Programs - Standard - Service;
Press " ";

In the window that opens, check the item "Select a recovery point";
If necessary, check the box to "show all the recovery points";
They show the time when a backup was made, and that happened (installation, delete, update);

Recovery points

Select the appropriate point and confirm;
Do not turn off the computer until the recovery end.

System rollback will occur. It will return to the state in which it was before the appearance of errors.

Other options

Scan the system with a good antivirus;
Clean the winchester from the garbage. Remove unnecessary files. But do not touch the system data. You can use the built-in Windows services (Start - Standard - Standard - Service - Disk Cleaning) or install programs for this: for example, CCleaner;

CCleaner program

It makes sense to correct the registry errors. But you should not do it manually. Use Registry Fix, Registry Boot and the like;
If you have an installation disk with the system, try reinstalling it or restore damaged files;
Update all drivers. Load topical updates.

If the "blue screen" appears when turned on

If the "blue screen of death" appears immediately after turning on the computer, you will not fall into the system. And it will be difficult to fix something. Therefore, you need to start a PC from the boot disk or drive. If you have no such, use the installation CD with Windows. The free program from DrWeb - "Live Disk" will also be suitable. It can be downloaded on the site "Freedrweb.com":

When starting a PC (on the first "frame"), the key will be specified to click on to open the settings ("Press to Enter Setup"). It is usually F1, F2, F5 or DEL;
Click on it. BIOS parameters will open. In them, all controls are tied on the keyboard;
Click the Boot tab;
Item "Boot Device Priority";
There will be a load order. Put the device on the first place 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 an external media (do not forget to insert it);
If it is a boot disk or CD with Win distributions, try reinstalling them;
In Live Disk, there are also means to resuscitate the system;
After recovery, change the order order again to run from the hard disk.

It will work if the problem arose due to software failure. But it will not help when breakdown equipment

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. Do not attempt to improve PC performance if you do not know how to do it. If you follow the precautionary measures and follow the state of the system, the "blue screen of death" you can hardly bother you.

With some failures you can cope with yourself. But if BSOD appeared due to equipment breakdown, it will have to change it.

Today we will tell you what is the blue screen of Windows 7 death, what to do when it appears. We often meet this phenomenon when the computer suddenly decides to arbitrarily reboot. Blue Death Screen Windows 7 Error codes are given together with a plurality of low-touch inscriptions. Knowledge of the values \u200b\u200bof the main codes will help to eliminate the problem with the greatest efficiency. If we see the blue screen, it means that the operating system cannot correct the situation. The occurrence of the screen reboot is completed, and all incomplete data is often lost. The main causes of such a phenomenon are: a software error, problems with PC hardware elements.

Causes of BSOD - Death Screen

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

The operating system to establish the causes of failure is not easy, but the BlueScreenView program will help us. This application independently scans error data files and shows more detailed information about failures.
The classic tool "View Events" Theoretically allows you to get similar information, but in this case it will be displayed along with information from the system log and messages about the "drop" applications. BlueScreenView receives information about all the deaths in the system.

Here you can see many useful information about failure, among other things:
Driver that caused a mistake.
An error description.
Error code.
Time and date of error.

Let's call the main causes of "blue screen":
Most often, the problem lies in the driver malfunction of one of the computer system devices.
The breakage of the PC component, such, for example, can be a video card or RAM.
Incorrect acceleration of RAM or processor.
Configured with errors.
Incompatible equipment, conflict of individual PC components.
The computer overheats.
There are viruses in the system.

Experienced users and developers can apply a more complex tool from Microsoft called WinDBG.
Error codes
0x00000001
This code may appear if there are difficulties with the compositebus.sys driver. When the portable or multimedia device is first connected to a PC, it sets the driver, and the USB is reset. An error causes simultaneous appeal to compositebus.sys. If you try to install a third-party driver, a similar failure may occur.
0x00000002.
The device queue was not busy. The problem lies in drivers or hardware. To correct the position, you need to update the drivers. Also, the computer needs checking for viruses. The registry will have to be cleaned. Hard disk Check for errors will also be useful. If this does not help, update the operating system to the current version.
0x00000003.
The error is also caused or hardware environments. The algorithm of correction is already familiar to us: check the hard disk for the presence of failures, clean the registry, looking for viruses, eliminate them, update the drivers. If all this turned out to be useless, load and on your computer the current version of the Windows operating system.
0x00000004.
This code indicates an exceptional invalid situation with access to data. The cause of the failure can be the hardware part of the PC or device drivers. The recipe is already familiar with us: from all extra, eliminate viruses, updating the versions of the drivers. If this did not help, you will have to go to a more modern operating system.
0x00000005.
This failure is associated with encoding error in the http.sys element. The operating system will have to updateso that the position is not repeated. This error occurs when the driver refers to the KeattachProcess function, with the problem occupied by another process. Using the KestackAttachProcess function can become more efficient in this position.
0x00000006.
This error is also associated with KeattachProcess. Here will also help the transition to the KestackAttachProcess feature. Among other possible reasons for this failure: breakage in the power supply, failure of memory, overheating. It is necessary to check the power of the power supply, test the hard drive and make sure that there are no viruses in the system. If this does not help, update the operating system.

The death screen is called in Windows 7 system errors belonging to the category of critical. OS hangs, and the latest user changes are not saved.

The situation is not the most pleasant, but often found in computers with the "seventh" modification of the system.

The general algorithm for the elimination of this problem does not exist, as it depends on the causes that caused its causes. Below are the specific recommendations that should be taken to effectively resolve the situation.

Why does the screen of death appear?

All abundance of the reasons for BSOD are classified in two large parts:

Software;
Hardware.

The first includes malfunctions in system services, incorrectly installed software (including providing the normal functioning of equipment - driver), viral infection of PCs, conflict software, etc.

The second part of the reasons causing the blue screen in computers on Windows 7 lies in the "hardware". Recordsmen in popularity are such essential components of PCs as Winchester and RAM.

Often, after introducing the user in the PC an additional RAM bar or because of its poor contact in the slot, the blue background with white letters will not slow down to greet the owner of the computer. Also, not rarely a hardware with the hard drive is the causes of the critical error and hanging OS.

Blue screen itself in Windows 7 is informational. Its text contains recommendations for troubleshooting and notify the user about specific error codes that caused its occurrence.

That is why it is necessary to carefully examine all the launched screening screen. By rewriting or remembering the error codes from the bottom of the screen, it is possible to surgically to diagnose and quickly get rid of the problem.

Unfortunately, the user often does not have time to familiarize themselves with the displayed report, so this manual begins with the admission of the abolition of the automatic restart of the PC after an error occurs.

Computer settings

If the user did not have time to fix the necessary information from the screen, then a small setup of the PC will be required.

After that, you can, having learned the code, to find an effective "medicine", capable of curing an iron friend.

Next steps:

It is recommended on the resource "bsodstop.ru" to explore the value of the error code. For example, "0x0000004e" may appear due to the incorrectly installed driver.

To find out what accurately caused a problem in the system, you should use the BLUESCREENVIEW application, which automatically reveals files, due to which a critical error occurs. From the user only to install and open the application.

By a detected file, you can find out for what equipment it is necessary to reinstall the driver. From the above figure, it can be concluded about difficulties with a graphics accelerator, since "ATI2DVAG.DLL" is associated with the video card.

In this case, the installation of the correct software for the video screen will make rid of the death screen.

After reinstalling the driver, you need to restart the PC. If you failed to correct the problem, then there are still other reasons.

Often an error occurs after updating or installing a new program, while the optimal output from the situation is the exercise of the OS rollback.

Range

The new program or the game also serve as often culprits of system failures. In order to return the OS to an efficient state, such consistent steps must be performed:

Installing OS updates

Microsoft professionals do not remain aside and make their efforts to troubleshoot BSOD.

They continue to support the already outdated "seven" and produce upgrades that have "fixes" in their composition, correcting system errors, due to which the blue screen occurs.

To update, you will need to perform the following steps:

The next reason for the problem is a trial lack of memory in the system section of the hard disk. Checking this version does not take a long time.

Lack of memory

On the official resource of the developer of Windows 7, it is written that it requires no less than 100 MB of free space on the system volume, however, practical experience has proven that for the normal work "seven" requires a free fifth of the system volume.

To make sure there is a sufficient location in the section, you just need to open the computer in the conductor.

After making sure the place of adequacy for the operation of the OS, go to the analysis of the presence of system errors through the event log.

Analysis of the event log

To do this, make the following steps:

Antivirus and viruses

Often a simple disabling of the antivirusman leads to troubleshooting. If, after deactivating a protective application, the blue screen has stopped appearing, it will take full removal of antivirus.

Malicious utilities also cause critical errors, and regular PC scans are required for their presence. Many developers of antivirusers have versions functioning with removable media.

For example, "AVZ". After writing an application to a CD or flash drive, you can carry out the treatment of a PC from malicious utilities.

BIOS

Incorrectly entered parameters in the BIOS also often cause failure. Correct the position. You can reset the bios settings to the initial state - "Default".

Equipment

The simplest revision of the flap wornity and the correctness of their connection sometimes allows you to quickly identify the cause of the failure.

If the user has the appropriate experience, the system unit (Sat) is required, check the connections of all components of the computer.

For example, when, on the results of attentive viewing of information displayed on the blue screen, the lack of access to RAM, it is necessary to carry out the following actions:

Turn off the PC;
De-energize the computer by turning it off from the power supply;
Remove the SAT cover and disconnect the RAM cards;
Wipe with a dry cloth contacts and insert equipment into place;
Run PC;
Make sure to eliminate the problem.

Similar activities can be made with other PC components, such as Winchester and Sound - video cards. If there is no positive result, it is possible to fail this component and a replacement for a new one is required.

Diagnostics of equipment can be performed using special utilities. For example, "Windows Memory Diagnostic" allows you to identify problems with RAM.

The application writes the image of the boot disk. This ISO must be cut into a CD and load a PC from it. The program will be tested in cyclic mode.

To stop the analysis, you must reboot. Also in Windows 7 there is a built-in program for analyzing RAM. In order to use it, the following steps must be performed:

To minimize the risk of the emergence of the BSOD, the following is recommended:
