Recently I bought MSI GTS 450 512Mb/OC and I am having weird problem with it. When I play games after 10~20mins PC crashes - screen turns black
and GPU cooler turns like crazy (my guess is that it turns @100% because noise is really loud). When I press restart PC restarts and loads but screen is still
black and GPU cooler runs like crazy. When I turn off using power button and start PC everything is normal again.
I was using XP when I tried it first but after upgrading to win7 it still crashes.
I have tried 280.26, 275.33, 267.59 and 266.58 Nvidia driver versions - no changes, having same problem.
GPU temperatures - idle 30~35C, on load 45~58C (63C max with GPU burn-in test).
Tried all benchmarks on all settings with MSI Kombustor - everything runs fine, no restarts/crashes. It crashes only when I play games.
Games I played Half-life 2, Left 4 Dead 2, Fallen Earth, Team Fortress 2 - all played on average graphic settings.
Operating System: Microsoft Windows 7 Enterprise SP1 32 bit
CPU: Intel Core 2 Quad Q6600 @ 2.4Ghz (not overclocked)
Motherboard: Gigabyte GA-G31M-ES2L v2
RAM: 2 x OCZ Gold XTC 1GB (OCZ2G800R21G)
HDD: Western Digial Caviar Black 500GB (WD5001AALS)
Optical Drive: None
PSU: INTER-TECH SL-500G 500W (Info about PSU - http://i56.tinypic.com/2n05y7p.png)
Could it be PSU that causes this problem ?
Or maybe I bought bad GPU ?
Or maybe something else (maybe motherboard because it was kinda cheap) ?
I will appreciate any help!
P.S. When I put back in my nvidia 7900 GS everything runs fine, no crashes.
