The thing is, it was working fine up until one day, I hadn't installed anything new or anything like that, the graphics were just like that. It can't be overheating, since I've cleaned the fans recently, then left my computer off for a day. I ran WoW as soon as I next booted the computer; nothing changed. So it's not faulty, maybe it just broke.

As I said, I've installed the latest drivers from the nVidia site. That link you posted is to the latest drivers. Basically what I'm saying is, I've already got those drivers installed.

I redownloaded the latest 32-bit Vista nVidia drivers from their website. Driver version is 7.15.11.5818, and the driver date (which I assumes means when it was released) is 12/04/2007. I know someone running a GeForce 6200 on Vista, but he doesn't get this problem on WoW.

When I was about to play CS:S one day, I got ingame and noticed that the graphics were..distorted, shall we say. I didn't know what the problem was, so I checked my other games to see if they worked. Games like WoW and Battlefield 2 had the same problem, yet Stepmania didn't, so that led me to think that maybe it was a problem with DirectX. I'm running Vista Ultimate 32-bit, and my graphics card is a GeForce 6600 (which as far as I know supports DX10). I've tried everything I can think of, short of reinstalling Vista: reinstalling my graphics drivers, cleaning the graphics card, and making sure it's properly seated. In my dxdiag there's no tabs for DirectX info, which I recall there being when I had DX9.0c installed before I got Vista. The only advice other people have been able to give me is to buy a new graphics card, which I can't really afford. I've attached a picture of the problem, any ideas?
