The computer can't be turned on because of the wet weather.

1, press the power button and there is no response-check the external power supply first, and then see if the motherboard is powered on if there is no problem. There will be LED lights on the motherboard.

2. The motherboard does not turn on when it is powered on-it is generally a problem of insufficient power supply and switch circuit. If conditions permit, use meters.

3. There is no signal when the fan turns to the display screen, and the host does not give an alarm. Most of the problems are memory, followed by graphics cards, and graphics cards have few problems. Call the police if there is something wrong with the video card.

4. Check the contact between the host power cord and the socket and chassis. It is possible that the power cord is not plugged in properly, resulting in no power supply to the host.
