I have a PC I built myself that's been sitting unused for about a year, worked great for another 2 years before that. I've figured out a workaround to the problem, but it's only a temporary solution.
Basically, pressing the power button or jumping the PWR SW leads does nothing. However, the computer starts up just fine after jumping the green and black wires on the 24 pin connector thus forcing the power supply on, then removing the jump and letting the PC shut down. After this, pressing the power button starts the computer just as its supposed to and it stays on. If I shut the PC off, I have to repeat this process to start it back up.
I've tested the PSU with a multimeter, all the voltages are correct. I'm really confused as to why it'll only start after forcing the PSU on once.
Motherboard is ASUS A8N-SLI Premium, PSU is 500w if that helps.
