I have a very odd issue I have never encountered with a computer so far. Basically the PC does not turn on anymore most of the times. It does eventually after like 10 tries of using the power button. When it doesn't start, just nothing happens EXCEPT that the USB power turns on but nothing else boots. I usually put it on and off multiple times until it actually boots "normally" again. What is weird here though, is that the mainboard is doing some weird stuff then, it basically turns on and off multiple times until it eventually catches itself and boots the PC normally. I am not sure if that is just because the PC didn't boot properly multiple times.
I have no idea what the issue might be but maybe my PSU is just faulty and no, I have no other to check right now. I already tried to check all the cables inside my PC and even went so far to replug them all on the mainboard and PSU. I also changed my power socket and tried turning off/on the PSU power button. Nothing changed anything.
The problem appeared out of nowhere a few days ago and I never had anything similar before. My PC is round about 3 years old.
Any ideas what it could be or what problem it sounds like? Anything I can still try except replacing the PSU?
