(1) The reason why the computer has a black screen when it is turned on and restarts it several times is: the power failure of the host.

2) Due to the serious leakage of the filter capacitor in the power supply of the host, or the leakage or damage of the electrolytic capacitor at the voltage output end, it will cause insufficient charging when booting, and it will not be able to transmit enough voltage to start the computer, resulting in a black screen, when it is turned on several times, the power in the capacitor is sufficient, and the voltage of starting the computer is reached, and it can work normally.

3) Solution: Take off the power supply and repair or replace it with a new host power supply, and the problem will be solved.
