So I purchased a computer around two months ago and built it just fine. The specs are as follows:

2 EVGA 8800gt's
intel q6600 quad core
620w hx corsair psu
evga 780i sli mobo
8 gigs of ocz ram
64bit windows vista ultimate

Now, as of the past week, I have been experiencing a problem with my new pc. While playing a game (Age of Conan) my computer throttles down and stutters, appearing frozen. It takes several minutes to be able to do anything so i generally just turn the computer off by holding down the power button. It takes a few minutes of gameplay which leads me to think its a heating problem.

Rivatuner shows my GPU temperature at 64c. The processor itself idles around 41-45c and maxes at 55c when its hot during the day.

I'm running the stock PSF and have seven fans blowing into my cooler master se case.

Age of Conan was perfect for almost two months until this problem began. The game takes advantage of only one graphics card even though I'm running sli.

Could there be simply not enough wattage to handle my machine and the signs are manifesting this way two months later?

I've eliminated all the dust possible and have reseated the heatsink. I've read that the stock PSF was fine if not overclocked.

Any ideas as to what might be the problem and a solution? I'd really appreciate your help.

You do realize that most BISO have an autoshutdown when the cpu reaches 140f. degrees, your gpu is at 147, you need to move more air or you'll soon need a new gpu. Use arctic silver thermal paste, and thinly but not a transparent layer, to much paste will act as an insulator, the paste is only to aid in filling gaps between the metal surfaces durring temp changes. After you remove the heatsink, clean the areas, apply paste, place heatsink and remove and check corner to corner coverage, then secure. Clean the fan blades with q-tips and cleaner (on the swabs, never spray anything into case, duh) Remove fans to clean them if possible.

You may want to look into a case with better air movement like the Antec 900.

Clear away IDE cables, bundle the to case wall whenever possible, add more fans to open case expansion bays, and make sure fans are moving air in a sensible maner, low to high, front to back. you dont want any 2 fans on the same side moving air in opposite directions reintroducing hot air back into case. Or you may want to look into water cooling. But get the temps down.

If you do have 7 fans blowing INTO the case, that could be the problem, you'd be better off with (for example) front fans blowing IN and rear fans blowing OUT.

4 fans on the side are blowing in.. one at the top is blowing out..

one in the front near the harddrive is blowing in... and a rear blowing out.

you think it could be the GPU then?
