When the host power switch is pressed, the motherboard is not powered up and the monitor is not responding, nor is the sound of the alarm issued.

This failure first checks to see if the BIOS has been compromised by a virus. When the computer has a debug card, it can be judged by whether the BIOS LEDs on the card are lit. If the boot block is not damaged, the speaker has "beep" beep, but the monitor is not lit. If the boot is damaged, power supply, hard drive light, and the CPU fan turn normally, but do not start, then the BIOS can only be rewritten through the programmer to solve the problem.
