Alright, general specs of a system I just built.

-Intel core 2 Duo, 3ghz
-8gb ram - Kingston cheap stuff.
-2 Zotac 9800gt in SLI
-2 WD drives in raid 0
-P5N-D 750iSLI MB - Asis
-HEC 750W PS, 2 12v rails - Each Video card checked and double checked to be on different rails.
-Windows VistA Basic

I write this message from the computer in question. Loaded Windows VistA Home Basic, installed WOW, Dawn of War II and some other basic crap. I patched the system through windows update, updated to DX10, Nvidia 182.06 Detonator drivers.

Once I loaded up WoW I was able to play for about 90 seconds and the computer turned off. Not like, standby or something, like I pulled the power cable outside of the power supply.

My first thought was that the PS couldnt handle the load, but I don't think this is the issue at this time, though I may be mistaken. After I tinkered with the power supply cables I loaded up Speed fan. Under completely IDLE circumstances (I.E. now) one GPU is at 63C and the other is at 60C, the CPU used to spike real high but I replaced the OEM stock pos with an aftermarket copper heatsink.

Side note: I have Arctic silvered everything. North bridge, south bridge, heatsinks on the video cards, and CPU.

When I load a game the GPU heat does go up, I tab out of the game to check the heat I've seen as high as 68C, but the system turns off randomly so I am not sure the highest it gets.

Ok, random jerry-rigged stuff I've done - I slapped 2 120mm fans on the case wall, as it is slotted to allow for air flow. These two fans are blasting air right on the two video cards. I currently have a total of 7 fans 3 120mm 4 80mm fans, the thing sounds like a damn jet. Also, I touched the video cards while in use (I grounded myself :p) in places that were not I put extra little blue zalman heat sinks that were designed for ram on video cards.

I've made sure all my drivers are up to date, .... I really dont know what to do at this point, I would very much like some outside thought on this :(

Thanks everyone.
Justin

Will do, CPU temps under load were like 60C, since I got the new aftermarker cooler they are like 50C under load.
