Trying to figure out what is wrong with a friend's pc which won't post. It was working a few months ago and he put it away for a while and then when he tried to use it again it wouldn't turn on. Nothing had changed during this time. I tried the paperclip test on the psu and it didn't work so he ordered a new one which the test does work on but the computer will not post still.

At this stage I have the mobo and cpu on a table, breadboard style, and I tried manually jumping the pwr on and I noticed the psu fan moves almost inpercepibly once when doing so, but no post, no beeps, nothing. It also does this only once before having to power the psu off, and back on again.

Even tried things like taking the cmos batt out for a while and of course checked all the power cables and outlets. Ram is out atm since I just want it to post.

mobo is p5ad2, processor is a core2 intel I believe. new corsair 650w psu.

Any help appreciated.

All the basics are covered. Its going to be something abstract. Almost has to be that the mobo or cpu went bad but it just seems strange that it would be spontaneous.
