Hardware Failure? AutoRestart...

[LegendKiller]

Spec:
i7-950
Asus Sabertooth X58
1800MHz 4GB RAM Kingston Hyper X Genesis
750w(Cheap PSU for $40, This is not the problem as it would be causing restart on stock BIOS settings)
1TB HDD
Evga GT 220
Haf 912

OC:
4GHz(4008MHz 24x167)
CPU Vcore 1.34v
HTT On
RAM @ 1667MHz
QPI 1.29v
RAM Vcore 1.64v

What's causing the restart?

Note: This is not a OverHeating problem!!!

BTW this been happening for a month now...

I been searching on google and some people with same spec or so said that they RMA the PSU and it's not the PSU as it occurs again... What im think that is causing the problem is my motherboard... Should I RMA it or call them about it? Im getting Random Restart... I posted something the same at tomshardware.com(Go to google and search "OC Fail? Random Auto-Restart..." without quote) but no one is helping me, at first I tho it was OC that was failing, now it's not as it's restarting on stock clock....

Do you have another PSU you can use to test like even a 500W,just to make sure.
and for it being a month now why did you wait this long to find out the problem,just asking.

It took a month because I was seeing what's the problem, I turned off OC and it havent happen for 2-3 days than after that it started coming up/happening on stock clock so it's not my OC, i'll try but it's ganna be hard to get a PSU to test it since my PSU is all zip tie and my bro's PSU is zip tied too...

Do me a favor, unplug your power and reset switches from your mobo.
just yank the wires off.

if not do everything you can to lower the computers watts use or get a different psu from somewhere and try that for a bit.

as well do a full once over on the computer and clean all heat sinks, check everything for bad caps, and clean all components in the system,check to see if anything is overheating~ blocked fans etc.

as quick once over with memtest and the like might be in order as well.
