MSI GTS 450 512MB Problem

Hello all,

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 -

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.

  1. It can be your PSU if it is not providing enough power but have you monitored your temps?
  2. GPU temperatures - idle 30~35C, on load 45~58C (63C max with GPU burn-in test).

    All other temperatures are seems normal too.
  3. Yes temps are normal.
