After about 1.5 hours of gameplay (COD:Waw and GTA IV), my PC locks up solid, looping the same half-second of audio.
On the other hand, my PC runs GPGPU functions (SETI@home) for 10+ hours without a hitch.
The situation: My PC, working stable with the following specs:
E6750 @ 3.4Ghz
2GB Crucial Ballistix DDR2-1066 @ 850Mhz (to match system bus pre-multiplier, seems the board doesn't like DDR2-1066 :-\)
MSI P7N SLI Platinum @ 1700Mhz FSB
WD Caviar SE-16 250GB HD
500 Watt Coolermaster PSU
Radeon HD 4850
Was upgraded to an nVidia GTX 260 (1st gen) that was working fine in my cousin's system with specs as follows:
E8400 @ 3.2 or 3.4 (not sure)
4GB Ballisitx DDR2-1066
Asus P5N-D
2x WD Caviar Blacks in RAID 0 (500GB each, I think?)
550 Watt Thermaltake CPU
Anyways... being as I added a known good part to a known good system, I figured it might be the weakish power supply since I'm overclocking and all. I borrowed my roommate's TruePower Treo 550 to see if a weak power supply was the culprit.
Instead of 1.5 hours to crash, it's now 2.5. I know heat's not an issue. Thermal event logs don't show the GPU getting above the 50s (I have the fan running at 100% in a well-vented case).
My question: Is it possible the PSU is the culprit? If not... what else could it be? I've uninstalled all my ATI drivers prior to even installing the card, then installed the latest nvidia drivers.
Thank you much for your time, I look forward to your response.
