When you turn on the laptop, a blue screen: troubleshooting, possible causes, instructions on how to fix the problem. The blue screen of death and its causes. Decryption and elimination of blue screen

The Blue Screen of Death is familiar to every user of Windows operating systems. For some users, it appears so often that they begin to think that this is normal. But this is not the case. Let's see what the blue screen of death is. This is an error that appears during startup or after an abrupt shutdown of the computer. It indicates that there are 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.

Blue screen of death, its causes

The reasons for the appearance of a blue screen can be divided into two main groups:

• Systemic... Operating system problems: no required files required for correct Windows work, incorrectly installed OS, infection with malware or a file, and so on.
• Hardware... Problems with computer hardware: malfunction hard disk or video card, processor overheating, and so on.

In order to accurately determine the cause of the error, you must carefully study the content of the blue screen. After all, it is on it that all the information the user needs is indicated, namely: the reason for 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 provokes a blue screen. Therefore, be sure to check and scan other directories.

Diagnostics

Blue Windows screen or a memory dump - a reflection of a healthy (or not quite) state operating system at a certain period of time. Since immediately after the appearance of a critical error, after which an abrupt 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 or photograph.

The main trouble is that the blue screen is shown for a strictly limited time. Then the reboot mechanism starts. Therefore, an unprepared user who does not know where to look may find it difficult to have time to rewrite the necessary information.

To disable auto-restart of the device, that is, when the computer or laptop immediately starts to reboot, immediately after the blue screen of death appears, it is necessary to activate the recording of small memory dumps, that is, part of its important content. This requires the following steps:

Now the blue screen of death when Windows 7 boots up will not immediately disappear, so you will have time to rewrite the necessary information.

Decoding the error

Since any problem can cause the blue screen of death, it is necessary to identify it in order to fix the error.

As soon as you managed to take a picture of the blue screen when Windows boots or write down the information that appears on it, you can proceed to decrypting the error that caused it:

• The first line of the system in English politely notifies that a critical shutdown of Windows has occurred.
• It goes on to explain what exactly caused the problem. This can be the name of a file or driver of a video card, audio card, TCPIP.SYS, SPCMDCON.SYS, DXGKRNLl.SYS, NTKRNLPA.EXE, NETIO.SYS and so on. If this line is missing, then the cause of the error should be looked for in the computer hardware.
• A user-readable error name such as DRIVER_IRQL_NOT_LESS_OR_EQUAL indicates that an error occurred while installing the driver.
• This is followed by a large body of text in which Windows suggests a possible solution to the problem. For example, check if the drivers were installed correctly, start the check disk service, perform a system restore, and so on.
• After the word STOP, the technical error code is indicated for more accurate identification and elimination. It can look like 0x1000007e, 0x00000116 and the like.
• Below the system may re-indicate the names of files or drivers, such as TCPIP.SYS, SPCMDCON.SYS, NTKRNLPA.EXE, NTOSKRNL.SYS, NETIO.SYS and the like, which could have provoked a blue screen.
• Additionally, depending on the type of problem, Windows may display the memory address at which the critical error occurred. By analogy with the STOP code, it will probably have a format like Address 0x00000116.

Knowing this information, it becomes clear how to remove the blue screen of death.

Problems with a blue screen in 90% of cases are the most commonplace and appear among users who are poorly versed in computers, so they often neglect the installation system updates, drivers, correct uninstallation procedure, and so on.

Damage to the acpi sys file can cause a blue screen, so to fix the error, you must replace it with a workable 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. This is best done using a special software... One of these programs is.

With its help, it is also possible to check the presence of all 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 you wish, you can make a copy of the original files and save in any convenient location on your hard drive.

Death screen when booting or installing Windows

If you do not know how to remove the blue screen of death when Windows installation 7, please read the following information carefully. This error can occur only in three cases, if:

• faulty x64 operating system image;
• working image, but faulty hardware (error 0x00000116, IGDPMD64.SYS, fltmgr, ntoskrnl);
• BIOS setup was incorrect.

If, during the installation of Windows XP, the blue screen repeats over and over again, but you are sure that the computer hardware is in order, then the problem most likely lies in the faulty operating system image that you are using.

A blue screen during Windows installation or recovery can occur due to a faulty internal storage device (HDD) or incorrect formatting. Do not neglect the standard procedure for checking the operability of the used OS image, disk or flash drive. All this information can be found on the screen. You fix other problems in the same way.

Missing or damaged system files

If you are not sure how to remove the blue screen of death due to missing or corrupt 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 extension .SYS, .DLL, .EXE. To do this, you can use a special third-party shareware utility. One of the most popular is.

After installing the program, you need to launch 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 as well. If you are sure that it was the nvlddmkm sys file that caused the blue screen of Windows 7 or any other, the name of which you should know for sure, then you can check it.

As soon as the scan is finished, it will offer:

• replace the file if it really was damaged;
• proceed to check the rest of the system files if the specified file is not damaged;
• only delete the faulty file if you want to replace it yourself;
• do nothing, but open the folder with the damaged file to independent decision Problems.

Optionally, you can install other applications for automatic search damaged system files and their replacement. Some of them similarly identify and fix driver problems.

Reset BIOS

If you have recently made BIOS changes or tried to overclock the processor, then this may be the cause of the problem. Therefore, you should definitely try to return its default settings. This can be done in several ways:

Conclusion

And this article was considered: what is the blue screen of death, its causes. An explanation of the errors was given, and also suggested different options elimination of the resulting breakdowns. Now, if you see the Windows 7 death screen again, then you already know what to do.

You work like this at the computer and do not suspect that one day something might go wrong. It's one thing if technical problems arise. Then, even long before the computer fails, you assume that the fatal day for the computer is not far off. And if a blue screen appears, then you take it for granted.

The terrifying term has been around for a long time, but it has nothing to do with the death of the computer. The reasons why the blue screen appears are different, but the message itself warns the user that the operating system has encountered an error, and therefore the correct operation of the computer cannot be continued.

Typically, a simple restart of the computer resolves the error. Why it happens? The question is difficult, since there are various reasons why the blue screen of death appears, respectively, and the answers to the question posed will be different.

What can be one of the reasons for the breakdown?

First of all, you should be aware that a blue screen of death appears for reasons completely unrelated to the technical condition of your computer. The main ones are:

• operating system testing;
• using "pirated" copies of operating systems on the computer;
• "Leaky" computer protection;
• untimely maintenance of the hard disk;
• illogical configuration of the computer.

How to recognize the type of error?

It is easy to recognize an operating system error that causes a blue screen: it is displayed on the screen as a system code. You can just write down the error code and find a detailed description of it (and how to fix it) in specialized reference books or on the Internet. But for an ordinary user, the "translation" of machine code into a simple human language becomes even worse: scientific and technical terminology can lead you into a stupor. Only a well-trained specialist can understand all the subtleties of the message. And you will definitely not be able to eliminate the causes of the computer malfunction.

For an ordinary user, you need to give several useful tips on the question of why the blue screen crashes and how a person should act in a given situation.

First of all, remember if it was produced in Lately replacement of certain elements of the internal filling of the computer (RAM, disk drive, and others).

This could well have influenced the fact that device drivers began to enter into a certain conflict with the operating system, knocking down the performance of the latter. Restarting the computer can return the computer to a healthy state, but all causes cannot be completely eliminated. You will have to save all important data (documents, videos, photos) that were on the system disk, reformat it, and install the drivers necessary for your devices.

The blue screen of death also appears due to pressing certain key combinations. It so happens that the user simply made a mistake and "ran the code" that the computer cannot process. A simple reboot will completely save you the problem.

Could BIOS be causing problems?

Incorrect BIOS settings can also be the reason that a blue screen crashes. A skilled technician can eliminate this defect quickly, but the average user is better off resetting all settings, replacing them with the factory settings. The easiest way without certain skills is to take out the lithium battery for a couple of hours. Any changes made to the settings will be discarded and the computer will return to a working state.

Maybe it's time to check your hard drive?

Hard disk problems (and this can also be the cause) can be easily fixed using the CHKDSK utility. It recovers bad sectors, defragments, optimizes all tough disk. A deeper "repair" and check the hard disk for errors can be done using the Acronis utility. It is enough to load it from the installation disk and specify the logical partition of the "hard drive" that needs to be examined. The utility will bring your computer back to life.

It should also be remembered that viruses can damage the boot sectors of the operating system or move its working fragments. Changing the folder name (and viruses do it) can cause a blue screen of death to appear. Whole fragments fly out, without which work is impossible, drivers are removed. And there are many other unpleasant moments. For the time being, this may be imperceptible, but subsequently a blue screen will necessarily pop up. To eliminate the consequences of viruses will help with the help of a reliable antivirus program. In this case, you must have the latest updates to the antivirus program, since older versions may not recognize the virus.

Let's hope that your attempts have led to the desired result and the computer works. If a blue screen pops up with the same frequency (or even more often), then you will have to contact a specialist. Most likely, HDD has received serious damage, and any reinstallation of the operating system will not get rid of the problem. There is already a technical breakdown, so the Winchester will have to be replaced.

Prevention is better than repair

We found out the reasons why the blue screen pops up. It remains to talk about preventive measures and the correct use of computer settings:

• use licensed software and reliable antivirus programs on your computer;
• defragment the disk in time, so you will win in the speed of the computer and keep the "hard drive" in good condition for a long time;
• do not carry out an independent replacement of components without prior consultation with specialists;
• ask for help for more fine-tuning your computer, because great amount the dispatchers available on the computer are completely unnecessary for the average user, their inclusion slows down, overloads the processor and memory, and for this reason the blue screen of death periodically appears;
• use only drivers from manufacturers of all components, "branded" drivers will not cause problems, unlike "analogs", and you need to download software only from the official websites of the manufacturers; "Broken" versions of programs often become the reasons that a blue screen pops up.
• obsolete equipment is removed from support by manufacturers, this must also be taken into account and an upgrade must be done in time.

It may also happen that even a licensed version of an operating system will come into conflict with outdated drivers of the same outdated hardware. There is only one way out - periodically follow the latest technology and news from the manufacturers of your components. If certain parts of the computer are outdated and no longer supported, then it is better to replace them with an analog that has recently appeared.

We've covered the top causes of blue screens and how to fix the problem. Alas, self-repair does not always lead to a positive result. and a blue screen flies out with frightening regularity. And it also happens that it is after self-repair that the first appearance of a message about a software error occurs. We remind you that in 80% of computer breakdowns there is only one reason that “sits” in front of the monitor (do not be offended!).

The question of how to be and what to do if the computer crashes into a blue screen BSOD(Blue Screen of Death, which translates as "blue screen of death") is often asked by users of computer devices, since such a phenomenon as BSOD is quite common. The symptoms of a blue screen are very eloquent, more precisely, they are "bluish": the computer turns on and starts to boot, after which the Windows screensaver appears, and after a while the PC, without fully booting up, issues of blue color a screen with white writing on it.

BSOD: cause and benefit

Many users are unhappy with Bill Gates' brainchild - Windows. I wrote, they say, a curve operating system, which now produces blue screens of different configurations. But this attitude is wrong and unfair. Many do not know that if it were not for the BSOD, if the OS crashed, many computers could be damaged and a lot of data lost.

The fact is that Windows OS functions directly with the hardware of the computer, and if something suddenly goes wrong, the hardware of the computer device will receive an incorrect command, which can be anything (for example, delete all data from the disk). Of course, the consequences of such a command are obvious: data loss and PC breakdown.

But this does not happen, since BSOD comes to the rescue - a special defensive reaction of the Windows operating system that occurs when the OS is no longer able to account for its actions and control them, and therefore is forced to take decisive actions aimed at its own emergency stop. Say, so as not to break the wood in the computer.

Thus, a BSOD error, or STOP error, appears in cases such as:

• error in the Windows OS,
• hardware conflict,
• driver incompatibility,
• damage to the driver with which the OS controls the computer,
• damage to system files,
• physical damage to some components.

It often happens that a STOP error occurs when:

• launching pirated or inadequate software,
• when viruses get in,
• in case of launching third-party incorrect drivers,
• use of false antivirus software and other "left" products.

If a blue screen occurs, you should address the causes of BSOD and the consequences of operating system errors. Fighting a blue screen is not so difficult, and even an ordinary user can get rid of bsod in computer on their own.

STOP error identification

Sometimes error identification STOP not possible. The message about the blue screen of death looks, as a rule, not entirely clear, because it is impossible to make out what is written in the mysterious STOP error, since the computer is constantly restarted and does not allow reading the already illegible "non-Russian" text.

To understand what your operating system has written to you, and to start taking some action to solve the problem, you need to press the F8 key on the keyboard and hold it down the next time the PC restarts. After that, the menu for entering safe mode will appear. Find the item "Disable automatic restart on system failure" in the menu, and then enter the menu. Now when you start your the computer gives a blue screen with white entries and will remain in this position until you press the Reset key.

In order to get rid of the blue screen of death, do the following. Start by trying to boot your computer from a Live-CD of some kind. This will help determine what type of problem you have - hardware or software: if it is hardware, you will not be able to boot from the Live-CD, and the PC will persistently issue BSODs.

Then proceed as follows:

1) Restart your computer, or better turn it off and then turn it back on after a while.

2) Remember what you inserted into the computer on the eve of the problem. Or, perhaps, you changed some "piece of hardware" - maybe it didn't make friends with Windows? Perhaps you have installed some kind of incorrect program? Try to return everything "as it was" and see what happens.

3) If the OS boots, and the STOP error appears only occasionally, update the OS by taking the update from the official Microsoft website.

4) Check if the computer has enough voltage. Because if it is insufficient, the computer can issue BSOD.

5) Check your RAM. This can be done using the Memtest utility (it is on the Live-CD) or using the RAM checker that is available on the OS installation disk.

6) Check the hard drive for sufficient space free space, and then to the broken zones using the MHDD utility (found on the Live-CD).

7) Go to BIOS, find the Default option and enable it. Save changes and restart your computer.

8) It will not be superfluous to run the "System Restore" option or activate the "Load Last Known Good Configuration" option (you can call the options via F8).

One of the following should help you eliminate blue screen on computer... If this does not happen, check your computer for viruses - they are often the cause of problems. Good luck!

Good afternoon.

Although, probably, he is not that kind, since you are reading this article ... In general, the blue screen of death is not a pleasant pleasure, especially if he was creating a document for two hours, and autosave was turned off and did not have time to save anything .. Here you can turn gray if it is a coursework and you need to take it the next day. In this article I want to talk about the step-by-step recovery of the computer if you are tormented by a blue screen with enviable regularity ...

And so, let's go ...

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

Eliminate the blue screen of death

1) Configuring the computer so that it does not reboot during a blue screen.

By default, Windows OS, after the appearance of a blue screen, goes to reboot automatically without asking you. There is not always enough time to write down the error. Therefore, the first step is to make sure that Windows does not restart automatically. Below it will be shown how to do this in Windows 7, 8.

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

Here we are interested in the boot and recovery options.

In the center of the window, under the heading "System Failure", there is an item "Auto Reboot". Uncheck this box so that the system does not reboot and gives you the opportunity to take a picture or write down the error number on paper.

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

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

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

I suggest using the site http://bsodstop.ru/ - there are all the most common error codes. Found, by the way, and mine. To solve it, I am advised to identify the faulty driver and replace it. The wish, of course, is a good one, but there are no recommendations on how to do it (we will consider below) ... Thus, you can find out the reason, or by at least, get very close to her.

3) How do I know the driver that caused the blue screen?

In order to determine which driver failed, you need the BlueScreenView utility.

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

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

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

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

What if all else fails?

1. The first thing we try to do when a blue screen appears is to press some keys on the keyboard (at least the computer itself recommends this). 99% that you will not succeed and you will have to press the restart button. Well, if nothing else remains, press ...

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

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

4. If the computer displays a blue screen right at the moment of Windows boot itself, and not immediately after it (as in step 2), then most likely the system files of the OS itself were corrupted. For recovery, you can even use standard checkpoint recovery utilities.

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

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

7. If none of the previously suggested ones helped you, I'm afraid that only reinstalling the system will correct the situation (and then, if there are no hardware problems). Before this operation, all the necessary data can be copied to a flash drive (by booting using the Live CD, and not from your hard disk) and safely reinstall Windows.
