I'm having an issue with my video card. I'm hoping it's not hardware, but it very likely might be. I'd like someone who knows about such things to give me an idea, if possible.

I have an i7, 6GB RAM, and HD5970 video card, for basic hardware foo.

Anyway. When I play certain games (not all of them), I get major graphical glitches. One one screen I get lots of floating circles -- not dots, circles. On the other screen, I get weird graphical artifacts in red, green, blue, and yellow. These go away if I minimize the game, or close it.

This happens on Mass Effect 1 and Grand Theft Auto IV. Oddly enough it does not happen on every game -- including Mass Effect 2, which runs fine.

I uninstalled my video driver and re-installed it. No change. According to Microsoft, my DirectX is the current max, 9.0©.

Any ideas? Is it the video card, or something else? Anyone have any clue? I'm really not good with hardware. The oddity is ME2 is fine, and it's /more/ graphically intense than ME1, so I'm kind of hoping it's /not/ hardware.

Have you checked the website of your video card manufacturer for an updated driver?

Yep. It links to Catalyst 11.6, which I already installed after uninstalling.

Try using Furmark to test for stability. However, don't use it unless you are okay with seeing your GPU temps skyrocket. This tool has actually fried GPUs.

Used it for a while. Video card went up to 92C(!!). Didn't crash or cause errors, oddly enough.

Do the affected games have the latest update?

Yep. Steam lists them as updated, and I did a verify cache of Steam.

Sounds like a video card issue to me. Do you have another card you can test your system with?

Do not. I'll be borrowing one from a friend I think. At least if that works, then it's likely the video card.

Have you tried testing the memory with Memtest?
