System TEMPS:
IDLE: CPU 26-31, GPU 75-80.
Load: CPU 55, GPU 90-95.
Load INCUBATED: CPU 63, GPU 97-101.

Problem:
System restarts sporadically every couple of hours, have not been able to determine cause. Currently unable to recreate problem, was witnessed personally earlier this week.

Things Tried:
1) Memtest - Passed 8 runs
2) Prime (4 Threads 1 Per Core) + 3DMark06 Loops at 1900*1200 ONLY GPU TESTs -Pass for 8 Hours
3) MHDD - Drives Tested OK, WD Test Tool - Drives Tested OK
4) FurMark Burn Test +Prime 95 + VLC playing HD movies + BS PLayer playing HD movies - pass for 8 Hours - Incubated and Non Incubated
5) GPU Tested seperatly in other system - Passed 8 Hours
6) System stressed with ohter GPUs (X600. 8800GTS) - Pass for two hours

The system still refuses to crash, I've seen it crash with my own eyes at the office.
Apart from a Video Card Driver upgrade I've made no change to the system.
Anyone have any ideas what else to try to recreate the problem and diagnose it?
Any help appreciated...

EDIT:Small update- system had faulty HD replaced,and cooling problems for CPU and GPU solved in the past.
 
Is this a fresh install of windows?

And is it a hard crash (like screen goes to black and computer boots up like you just turned it on)

Or do you get a BSOD?

Anything like that can give subtle hints...
 
It's a hard crash with no log.
There is no BSOD, which is why I'm thinking hardware failure.
Windows is a clean install from a week ago..
It restarts and at some times it doesn't start just shuts down.
There is a UPS in the office there is none where I'm testing
 
My initial guess was the PSU or something power related.
Since I verified the other components it's all I'm left with....
EDIT:It's still running Prime95 (4 Threads) + FurMark Burn Mode + BSPlayer for 12 Hours straight now incubated, and now I took it out of incubation. The machine is still stable?!?!??!

Yea, I was going to recommend checking the PSU next if it wasn't a BSOD (which can be software or hardware)

My friend had a PSU that was very very weird... it would take about 20 tries to power up, and once it was up and running it'd be fine, I thought it was a faulty power switch TBH... but we swapped it out with another PSU and it turned on first try every time. His would also cut out sporadically, sometimes it would run 24hrs of prime95 no problem, other times it would crash before you could get to windows. Finally we just put in the new PSU and left it...

So that'd be the next step... swap it out with a new PSU or a known good...
