The concept of "Blue Screen of Death" (BSoD) is translated as "blue screen of death". This is a common colloquial name for messages about critical failures in operating systems running MS Windows. Their appearance is due to the occurrence of fatal errors that occur when executing the code of any drivers or processor core. As a result, the only possible action for the user is to send the computer to restart without the ability to save the current data.
Typically, system default settings are set in such a way that in the event of a critical failure, the computer restarts automatically. After that, the operating system creates a log entry that describes the error that occurred. Information that you can use when you see the "blue screen of death" - errors and their codes, specifications, as well as some tips for troubleshooting failure data. Usually the message and advice are in a standard form, but the technical information changes according to the type of error that occurred and consists of:
- the code of the failure that occurred and itssymbolic name;
- parameters explaining the error, intended for debugging software;
- address of the crash site;- name of the driver in which the malfunction occurred.

What if the "blue screen of death" did appear? As we said above, the system settings assume an automatic reboot in the event of a BSoD. However, she will continue to do this until the error is completely eliminated. But we recommend disabling this option so that the user can record the fault code and find out the reason that caused it. To do this, open the "Control Panel", go to the "System" item, in which on the left side there will be a link "Advanced system settings". In the properties that open, on the "Advanced" tab, click the "Settings" button in the "Startup and Recovery" block, then in the "System Failure" block, uncheck the "Perform automatic restart" checkbox. Save your changes.

If you have a blue screen of death, write down the error code, it will help you find out the cause of the problem. After that, send the computer to reboot using the "Reset" button. When the system boots, press F8. From the menu that appears, select "Load Last Known Good Configuration".

If this operation fails,restart your computer again, press F8 again and enter safe mode. If the download is successful, try a system restore. If this fails, find your error code in a special table that contains a list of faults that cause the "blue screen of death" and try to find out its cause. After fixing it, try to restore the system again using safe mode.

If the problem that causes the BSoD is software rather than hardware in nature, to fix it, it will be enough to restore the system, or even better, reinstall it, and this error will no longer appear.
In order to to make sure that the hardware of your computer is in order, you need to test its hardware. You can check the hard drive using the MHDD utility, which runs from a 3.5" floppy disk under MS-DOS, and to check the status of RAM, you can use memtest86+, which also starts from a floppy disk.
By the way, the "blue screen of death" Windows 7 will soon cease to be relevant - this is the last OS where it will be present in its pure form. However, do not flatter yourself, because this does not mean that Microsoft will write the perfect OS. The fact is that BSoD will simply be replaced by KSoD (" blacK Screen of Death"), and from now on you will have to deal with the "black screen of death", that's all. In the end, we note that reinstalling the OS is only a short-term solution to the BSoD problem, and if the cause of itoccurrence has not been clarified, there is a high probability that it will reappear in the near future.
