PC won't turn on, occasionally.

[aliensRreal]

I have a PC in my possession that was involved in a power surge. The PC fails to power on occasionly and I simply cannot recreate the error. I tested the power supply voltages and things were fine, but when running a test supply everything worked fine for the rest of the day (probably 20 attempts to power on.) Now I threw a completely brand new power supply in the machine and on first try nothing worked. Same symptoms, not even a wince of power. Let it sit for five minutes came back and the machine booted up no problem.

I have run a troubleshooter that tested mobo, memory, and CPU. I have also taken out all PCI cards and memory to see if it would help, nothing. When I did this the PC powered on perfectly fine.

What could be going on?
