So i got new stuff to build a new pc. I got it all in and it was working ok, it wouldnt recognise the graphics card but there you go I put a new CPU cooler in and now it won't even post. I turn it on, it spins up for a few seconds then goes off, then after another couple of seconds it spins up and stays on, but no post beeps or anything, nothing on any screen. I've tried it with no ram, 1 ram, noting else plugged in, everything plugged in,nothing. Any ideas? Formatting the fucker won't work.
