motherboard

In the middle of use, my computer shut down. I tried to turn it on but it maybe comes on for half a second, shuts down, then flickers again very quickly about 2 seconds later before giving up completely.

So I took everything apart and nailed it down to the power supply, the mobo, or the CPU. I had an extra old power supply around, hooked that up and it had the same problems, so that can't be it.

When the 4 prong CPU connector is not connected, the motherboard 'functions' in that it stays on and runs the heat sink etc. Throw in the 4 prong connector and that's when it doesn't stay on.

So it must be the CPU, right?

Motherboard: ASUS P6X58D CPU: Intel i7-920

Bot are under warranty (supposedly) - should I get both replaced or what?

I've noticed that there are sometimes (large) differences between the reported total CPU usage and a summation of the per-process CPU utilization given by apps like top and wmtop.
