[SOLVED] Is my cpu or PSU stuffed?

[bensonae]

Recently, my computer stopped posting (black screen during post), there was no power led, the system had to be turned off by holding down the power button (simply pushing it didn't work), and every time the thing powered off, the motherboard led would blink for a bit then stop (no recognisable pattern). I have checked that this is not a memory issue, as all i had connected was PSU, motherboard and CPU. I have had the motherboard professionally tested, and it is apparently not the issue, and I thought I had eliminated the PSU as being the issue (all fans were spinning in case, and on CPU cooler), so does this mean that the CPU is kaput?

For anyone that is curious, this build has been overclocked to 4.5GHz on air since my last post, has not skipped a beat since.
