It's Win7 system, and it keeps prompting that it is shutting down. After a long time, the screen will be blue with pictures. Please help me.

There are many reasons for the computer's blue screen: it may be a system problem or a hardware failure, and its error code often has no clear diagnostic significance. When dealing with it, it is generally checked one by one according to the principle of "soft before hard".

General processing of blue screen:

1. Restart the computer: restart the computer in the current state or press the host restart button, or press the power button to forcibly shut down and restart. If the error prompt no longer appears, you can enter the system to run normally, indicating that the last exception was just an accidental program or system operation error, which is irrelevant.

Second, repair the system: If you often can't enter the system normally, press F8 immediately after booting to see if you can enter the safe mode or configure the correct mode for the last time. If you can, the system will automatically repair the registry after entering, and recall what you did when there were abnormal phenomena in the previous few times. According to the problem suspected to be caused by an application software (or driver), it should be possible to uninstall, then exit normally and restart to enter normal mode. If security software is installed, you can use 360 Security Guard plus 360 Antivirus or Kingsoft Internet Security and other similar security software to clean, optimize and accelerate the computer (delete redundant boot programs, defragment the hard disk, etc.) in security mode. ) and kill all Trojans and viruses.
