Automatic power-off failure when the computer starts up.

  

A computer that meets a computer will automatically turn off when it is turned on, and it will not respond when it is turned on. After that, it will not respond when you turn on the computer. System Home Xiaobian specializes in several troubleshooting methods, I hope to use the computer to automatically power off the power failure one: the specific situation is this: turn on the power switch, press the power button to start, the fan turns, the machine has motion After a while, the power is turned off, the fan does not move, the indicator light is not bright, and then press the power button is useless.
