I've been struggling here trying to find out what exactly went wrong, but I just can't. I messed around with a power supply and decided to wire up my own with 3.3V, 5V, 12V and all other connections needed on a ATX connector. The computer did turn on, but since the keyboard and mice were on but not working, I thought it has something to to with the PWR_OK not connected.I then connected it to ground and the computer did made a click and reset itself, then while I was holding the wire, it clicked about 2 or 3 times more and that was it. It doesn't POST anymore. No beep, just fan spin. Measuring the PWR_OK gives 4.97V, so it's being pulled high somehow, but a circuitry likely doesn't recognize it anymore.
I also searched on Google, but nothing... I think nobody does stupid stuff like that.
What could it be, which circuitry is responsible for that part?
I really want to get that motherboard back to work. It's not a expensive one, but it's that I don't have any anymore (now).
Thanks in advance.
EDIT: Grounding the wire still makes the computer click. Putting 5V does nothing.
