Desktop PC

Sometimes after a heavy power surge your desktop may not power up. One of the possibilities is that the power supply silent protector is on – some of the power supplies have that protector. 

Solution: 

Take the power cord out from the back of your PC, wait 1 min, plug the cord again and try the power button again.
Some of the manufactures like Dell for example have their own “Power LED Blinking/Beep Code” diagnostic system.
