If that passes then you have to do a stress test on the CPU. I think there is a liveCD for that somehwere. I will have to find it.
If all that passes then you are down to the mobo being the problem.
Also have you tried a Linux LiveCD at all?
not to dis you are anything. But how can he do memtest or anything like that if the motherboard isnt posting? I remember a few posts up he said that with no CPU in it doesnt beep at all. And there is no video even though the graphics card tested ok in another PC. So definately seems to be bad motherboard to me.
If it has a warranty still then RMA it. If not then you just need to find a replacement.
