Hit Microsoft's black-screen plan to recommend reinstalling the system .

There are generally three phenomena that cause the computer to crash and black screen: first: the computer power supply is insufficient, the power supply voltage is unstable, etc., or the power supply is broken.

Third: the system is broken, and the system needs to be reinstalled to solve the problem.

Fourth: The cause of the problem is the oxidation of the gold finger of the memory module or graphics card or the poor contact of the slot, which causes the computer to fail to boot up. Solution:

You can turn off the power first, open the computer case, dial out the memory module, use the eraser to wipe the part of the gold finger (that is, the place where there is a copper sheet) back and forth a few times, and then insert a memory slot back in, and you're good to go. If you don't turn on the computer after doing this, you have to check the graphics card, explain that it is a problem with the graphics card, and you can do it in the same way as above.

Fifth: Check to see if the cable between your computer and the monitor is loose.

If the temperature of the notebook is too high, generally in the summer, the notebook has not been cleaned and will know that it will be very stuck when it is shut down or restarted, if it is a desktop, open the side cover to see if it is very dirty inside! Or there is a fan that does not turn.

Turn off your computer and restart it. It may be a problem with the graphics card driver, or your computer has not been turned off for a long time, resulting in excessive memory consumption and making the system unresponsive!
