Asus 7900GTX problems

I just purchased a new computer a couple of weeks ago. It works great, except for the games.

After 25-30 minutes of gaming, the screen starts shaking, pixels are messed up and the whole system restarts. At first, I tried to install the newest drivers on the nvidia website. That didn't work. In fact, it made it worse, because Windows was starting to act creepy.

I tried cleaning out my drivers in every way possible, but couldn't. I had to reinstall Windows and put back the old drivers.

I read something on other forums, that said that the Anti-Aliasing settings were to blame. I don't about that, because I turned them off.

Heck, I don't blame the hardware, I blame the software. Thanks!

  1. What's your total system specs? What's the power supply?
  2. Motherboard: Asus P5WD2 Premium

    Processor: Pentium D 930 3.0Ghz

    Graphics Card: Asus 7900GTX

    Memory: Kingmax 1GB 533

    Power Supply: ThermalTake W0008RE 420W
  3. Actually, since it doesn't happen until some time has passed I think it might be a heat issue. Can you tell us what temperature your system is at? NVidia's ntune monitor should be good enough.
  4. After I start up the system, the heat is at about 45 degrees.

    I just finished playing right now (no problems) and the GPU was at 52 degrees. 5 minutes have passed and now it's at 50 degrees.

    (I'm going out right now. I'll be back in a few hours.)
  5. I think you should replace your video card with a new one ,the 7900gtx turned out to be a flaky procesor
  6. So do you think this is a heat problem?

    No, your temps are fine. I would suggest to RMA the card. Or, if possible, try a new power supply, although your current PSU is good enough.
  8. Okay, so I tested out Prey. I played at maximum settings for about 20 minutes. Then it happened again: screen freezes, annoying sound in the speakers, restart. I decided to change the settings a bit and only removed the anti-aliasing. It worked great. I played for about an hour and 20 minutes with no problems.

    Then I downclocked my graphics card from 650 / 1600 to the lowest 550 / 1400. I set the AA back to 4x and it works.

    I don't know if you can call this a solution ...
  9. Yeah just RMA the card
