Angry Nvidia 7900 GTX - Screen Tearing/Black Objects

While playing Call of Duty 4, I'm getting a lot of screen flicking, black objects, and screen tearing. Mostly the grass, players, and certain objects are black. I have installed the latest beta drivers, latest non-beta drivers, and right now I have 169.28. I am using a *fresh* install of XP Pro x64, with about 16 processes running when I play a game.

I installed the latest version of my chipset drivers (Nvidia nForce). One issue I did have, when I installed them my network card stopped working-- I had to install the Ethernet driver from Asus install CD in order to get online.

I did fix this issue somewhat by adjusting my fan speed control to 100% in my Nvidia control panel. The tearing was a LOT worse. Turning on/off vsync doesn't do anything.

I also attached a screenshot of what's going on. The black object isn't visible in this screenshot, but tearing is. It appears randomly, and the screen flickers some. Before I adjusted my fan speed control, tearing went across the screen completely. It also happens on HL2: EP2, but does NOT occur in America's Army.

I am not sure if it's hardware issue with my 7900 GTX or a software/driver issue. Thank you.

Here is my PcPitStop results:
Test Results Summary

The weird thing is crappy performance for video (70) compared to the usual 180...

Perhaps the temps are too high. What are the idle and load temps of the card? And is it overclocked at all?

nForce = 55c (131f)
GPU = 41c (105.8f)

Weird, I just played with absolutely no issues... but I don't think the problem is fixed. It seems to be a pick and choose problem. I did install the most current drivers out right now..

I'll let you guys know tomorrow when I play after work..

The problem isn't fixed. I installed the latest beta, 169.28 (I had 169.21 I believe). Any suggestions? My GPU temp isn't too high, either.

It seems like it actually got worse..

It happens on other games. Here is a shot from EP2.

Those are artifacts I assume. Could it be that your 7900GTX is stock overclocked?

Nope-- 650MHz core, 800MHz memory (it's a 7900GTX).

I just played COD4 with the 169.04 drivers, and I was able to play for about 4+ hours with only two glitches showing up on two separate maps.

Thats a horrible PSU, I had the same problem in BF2 until I changed my PSU and the problem stopped.

The Corsair 520W!

Corsair HX 520W ATX2.2 Modular SLI Compliant PSU (CMPSU-520HXUK)
