Distorted graphics

What appears to be happening is that when I'm playing some games in full-screen the graphics are distorted, all of them are fine in windowed mode. This seems to happen no matter which resolution I use, or what quality settings I have.

I thought I'd fixed it by forcing anti-aliasing in the nVidia control panel but it seems to have come back. Occasionally a reboot fixes it too. The card is an XFX 7900GS on Vista and I have the latest nVidia drivers.



Crop:


I get random blocks appearing over the screen and sometimes see wireframe in place of models.

This doesn't happen on all games, Quake Live, Neverwinter Nights etc are fine whereas BF2, Splinter Cell, SWAT4 or Gears of War have this problem - I think this may be a DirectX issue.

Any ideas?
Thanks.
 
Quake Live is new but is based on the Quake 3 engine, which I guess could mean it's old. The temperatures seem ok, but this happens as soon as I load the games, even if I force the fan to 100%.

I installed the latest DirectX and that didn't help either.

I guess it's time for a new graphics card then. The one in my laptop died a few weeks back too :o.

Not sure if it's any use but the images appear fine if I print-screen from my keyboard.
 
Well I just tried de-clocking it; it was running at 600Mhz core / 800Mhz (1600Mhz effective) memory which is how it must have shipped from the factory (it was pre-overclocked and at the same price I think).

I put the memory back down to what the 7900GS should be (450Mhz core and 660Mhz memory) and it seemed to work fine, so cheers for the suggestion.

Now I guess i need to decide whether I should get a new card, this one is starting to lack a little.

edit: I put it back up to the factory values and it also seems fine, now I'm really confused :D.

I think that may have just been coincidence, it's now doing it again. I've even tried putting it all the way down to 400Mhz core / 500 Mhz memory and I'm still getting it.

I guess my only option is to try it in another PC though it's somewhat of a hassle.
 
I've tried the latest (178.24) and ones from a few months back before I updated and they both seemed to have the same problem.

At least I can justify a new card now :).
