    I have been facing this problem last few weeks, I normal use my pc and shutdown it. Next day when I turn on my pc it won't start. There is power supply to motherboard (light in board and lan port are blinking) but when press the button nothing happens , just looks dead. So I took it to computer shop he reassembled the PC and turned on it was on. After 10days of usage again randomly next day pc won't turn on ,Same issue again. I was busy and didn't check my pc for two days , then after two days I turn on , pc turned on. Then after 1 day as usual I turned on it won't start so again waited 2days then it turned on. I was kind of wired so please help me. Is my motherboard or power supply is the problem.
    Specification:
    Ryzen 5 1600
    550w psu
    Asus prime A320-M motherboard
    Gtx 1060 mini
    Windows 10 pro 64bit

    Believe it or not, it’s almost certainly an even easier and way cheaper fix:
    Your power switch.

    Those symptoms are indicative of a failed power switch. Now granted it COULD be an issue with board or PSU, esp if your psu is a cheap unit . (Please provide make and model of psu so I can rule that out)

    A power switch is generally less than 10$ so it’s a cheap easy way to try to fix the issue.

    Abish, that’s a good power supply. While it’s not impossible for that power supply to be bad it likely isn’t cause most Corsair units are solid and well built.

    As for the switch, that’s likley the culprit. When the switch goes bad it simply won’t make contact all the tine when it’s depressed it may or may not send the signal all the way sometimes:

    If you want to be 100% sure, take the side cover off the tower and trace back the wires from the power switch to the connector on the board.

    Once located, unplug the power switch and then use a screwdriver to “bridge” the connection between the pins and see ignore it turns on. If so, your switch is bad. If not it’s likely a psu issue or a motherboard issue.

    Also the place where the wire from the power button plugs into the motherboard might be loose. Happened to me!
