When I tried to turn on my pc it doesn't start, so I unplugged him from the power over night, and now when I plugged him back he turned on,
So I tried to restart him (using the restart button) he done a full restart and he was working.
But when that I shut him down, he won't turn on except one led on the motherboard and on the fans. Exactly like last night.

What should I do?
I don't want to wait a 12 hours between each turn on of the pc.
