Ok so I am having problems with my nVidia Geforce 7900 GS graphics card and it messes up a whole lot when I play video games on my PC, and I don't know, but theres another problem, if this is caused by my video card as well but on some songs I try to play they'll go in slo-mo or not play them right. I am using Windows 7 32-bit and 64-bit. I've had my comp for 2 and a half years now and I've never had problems with the graphics card. I recently upgraded to 2GB of RAM in my PC and installed the RAM and the RAM seems to be working fine, and I've done memory tests on it and no problems were detected with it, I'm not sure if this is the problem or not. Here is a video of my graphics card messing up on me while I was playing EverQuest http://www.xfire.com/video/1623a7/ My graphics card messes up on just about every game I have.
