Hello all. Lately my computer has been randomly shutting down. I can be reading my email or playing a  game and the computer would shut down completely without warning. I tried turning on logging and checking the event viewer, only to see that there were no logs and all events were event 41 kernel power with all error codes being 0x0. I have ruled out my graphics card and memory as the cause after 3~ hours of memtest86 and another 2~ hours of furmark, and as I type this am running OCCT. So I am rather stumped as to the cause of this shutdown and am hoping I can obtain some assistance on this matter.

 

System Specs:

 

EVGA GTX 480

Asus Sabertooth z77

i5 3570k @ 3.40GHZ stock speed

8gb Corsair Memory @ 1333GHZ stock speed.

2x OCZ Agility in RAID 0 478 GB.

Windows 7 Ultimate 64 bit

Antec true power quattro 1200w

 

I made sure to default all settings on all my hardware but to no avail.

Is it really necessary to have a 1200w PSU in that system?

Does it have fan control knobs on the back? There are two different Antec true power quattro 1200w models.

Check your temperatures and see if anything is overheating.

The one I have does not have knobs on the back.

 

Temperature is not an issue as even under stress my CPU would cap at 65c running benchmarking software and my 480 would be around 90c, which is quiet normal. Funnily enough right after I finished testing and went to watch some youtube it decided to shut itself down while under relatively little stress.

Although you tested the RAM, id still reseat it to be on the safe side. Or try one RAM stick at a time and in a different slot.

I should have said that I have my A++ and am working on my Network+ as of current. I have tried all basic diagnostic steps, from reseating RAM to reapplying and reseating heatsinks and as I said I reset my BIOS to default settings. I have contemplated the PSU as the issue but I've monitored my voltages and they rarely fluctuate more than .1 on the 12v and 5v rails.

Hook up another PSU and try it out. Because from what you have explained and the fact that you know what you are doing and have done "everything" its probably a bad board imo.
