Graphics card problems
Hey everyone, I've had some problems with my graphics card, a GeForce Go 7900 GTX, rendering polygons out of wack in a bunch of games. Instead of trying to describe it, I'll just post some pictures. It started a while ago out of nowhere (as far as I can tell) and so far I've tried:
-Reinstalling DirectX 9.0c
-Updating drivers/trying different drivers (XTreme-G, Forceware, original CD included, and distributer updated)/clearing and reinstalling drivers...etc.
-Lowering gfx settings
But nothing seems to fix it. The games I've noticed the problems in are Neverwinter Nights 2, Call of Duty 2, Oblivion, and Portal (though those are the only games I've tried so I figure it's pretty universal).
The problem comes in anywhere from a few seconds of starting a game to say half an hour in, seems pretty random. The only "fix" I've found is to minimize then re-open the game, which will fix the problem for a while before it comes back again.
The polygon's generally go out "infinitely" (until they get covered up by some other object/terrain). Does anyone have any ideas? I'm _really_ hoping it's not a hardware issue, but I'm at a loss software-wise. Thanks for any help!
In this one you can see the polygon coming down from the face in the game and in the portrait, plus the other one sticking out the back:
And one more on the tail of the wolf:

It looks like overheating. Install a new/better fan on your graphics card.
agreed. Overheating is usually the cause when gfx cards behave randomly weird like that
Ah, k. I guess I dismissed overheating since it would fix its self for a while if I minimized then immediatly maximized, and since the problems could start very soon after starting a game. But, overheating does make since more than anything else :).
Can the fan's (and heatsink?) be cleared up on a laptop without having to disassemble it, or will that just be a half-assed job? Thanks!

I had very similar graphical glitches with my laptop, which I resolved by updating drivers and cleaning out the heatsink.
About cleaning the heatsink without taking apart the laptop: I don't know about your laptop, but with my laptop, that would do a really, really bad job.
I've got a Dell, and they had a service manual on their website that gave me step-by-step directions on how to take apart my laptop.
I had to take apart enough of my laptop that I could take the fans out entirely. Then, in between the fans and the heatsinks (one for CPU and one for GPU), I had a thick layer of dust almost entirely blocking airflow. There is no way I could have cleaned it out without taking apart my laptop.
That said, after I removed the layer of dust blocking my heatsinks, GPU temperatures went down by about 40 C under load, and I got a decent performance boost!

That's exactly what I'm experiencing with my 7900 GT (desktop). I've forced the fan up to 100% (before it only seemed to be going to 40% with load), but it didn't seem to help much. Furthermore I often get crashing after seeing these artifacts.
You know, these sorts of things should be unacceptable. I shouldn't have to replace components on my component after I buy it. What concerns me is if I upgrade or replace this card the upgrade/replacement will only overheat, this card isn't even a year old.
