I shut down the computer, pulled my computer out from its cabinet under the desk, and unplugged the cord form the PSU.

It was unplugged for less than one minute before I reconnected the cord to the PSU, flipped the switch and hit the power button.

nothing

All the cables are connected correctly. Its a nice system that was put together professionally with a powerful PSU. 600watts.

It's normally on for days, even weeks at a time but never runs hot. This happened the last time I unplugged it too, and the next day I just decided to hit the power button for shits a giggles and it just turned on again.

I need this computer for school and I can't afford to replace the PSU, especially since the cooling system is directly hardwired into the PSU.

Its weird. This has happened twice and the only thing that works is leaving it unplugged for 6-8 hours. I've done literally everything else that has been recommended.
