Bad PSU or Mobo? need help, pc won't start.
Last response: in Components
Hey guys. my desktop turned off all of a sudden one time and won't turn back on and still won't. My first thought, it was the PSU but i think im wrong.
I did the paperclip test and the fan on the PSU DID spin, but it DID NOT spin (but twitch a little) when i did the test while all the PSU connectors are connected, except the ATX connector off course. But i think thats the wrong way of doing it.
So I unplugged all the connectors and did the paperclip test again. The fan spins, then I also test for voltage while the fan was spinning. All the voltage seemed normal (yellow: 12V, red: 5V, orange, 3.3V, blue: -12V, purple: 5V, grey: 5V).
So is it my Asus mobo? it's only been 4 months since i got it (Asus P5Q SE Plus). are there any other tests i can do??
thanks.

the PSU fired up normally on another desktop.i never touched the bio's since i built it. i never knew anything useful on there.
i wouldn't suspect a bad ram, since if it was the case wouldn't it just freeze or act very slow? mine just completely shut off.
ill reset bios once i can get my PSU back.
I'm not sure without having seen it. I'm just saying it is a good place to start before an RMA of the board. If resetting the bio's does not do it and the PSU checks out than next is ram then M/B. Let us know.
