Recently, my desktop computer is in use, suddenly automatic shutdown, then can not open, I thought is the CPU, memory what the reason, then open the chassis, one by one check, no problem, I puzzled, took my host to the aftermarket, inspectors open the chassis, the CMOS discharge three times, the computer normal operation.
If your computer is in normal use, can not boot, the boot CPU fan normal, but the screen does not respond, without any prompts, you can try the following methods:
1. Add ground to the power outlet of the computer.
2. If there is ground wire, first disconnect the socket, press and hold the power-on key for more than 15 seconds, plug in the power, boot normal.
3. If the above has no effect, have to the motherboard direct discharge, find boot box, find the motherboard on the CMOS discharge socket, short two pins.
Different motherboard, the instruction manual has the introduction.
