6600GT - 3d Computer restart problem
I recently upgraded my older geforce 440MX to a 6600GT dual DVI by XFX. I uninstalled the previous version of the nvidia drivers and installed the newest ones off their website. The system runs fine in windows, but when I tried playing LOTR: Battle for Middle Earth, I eventually get a hard reset of the computer. The higher I have the display settings turned up, the faster it restarts. When i turned it to like 800x600, low detail (all effects off, basically) it ran for about 5-10 minutes without reseting. I monitored the GPU temp while playing the game, and it didn't even rise more than 3C from the temperature in windows.
I tried uninstalling the newest drivers and installing a slightly older version of the drivers but still had no luck.
How should I go about troubleshooting this problem? I don't have many other new 3d games that I can use to test it, so any 3d testing would have to be with specific testing apps. Reading a little bit, it seems somewhat possible that PSU could be the culprit, is this likely?
I have not had a single restart when in Windows, only when running games (and it was definitley not as fast as it should have been, given the chipset).
Let me know about any suggestions
*EDIT* And if it matters, I'm running dual displays, both on DVI.
