Update:

I ran Prime last night for about 4 hours and everything seemed ok. Came back to find the computer still running but no signal to the monitor. Computer wasnt sleeping and the MOBO post code still said "FF", "fully F**Ked" IMO. Hard powered her off and said forget it for the night. Woke up this morning and decided to re-apply AS5 due to the large diff. in temps between the cores, almost 10 degrees under full load and 5+ at idle. Go to power on and now im recieving a post code of 82 "enable ATX power supply". No bigge I have seen this before, clear CMOS and she will boot. No dice. This leads me back to my orginal theory that the PSU just cant handle the full load of 7 fans, Pump, OCZ ram cooler, Q6600 OC, and the 8800 GTX. Next step looks like borrowing a friends PSU to check for stability.

Any thoughts ?

Thanks
