video card trouble, need help

[Cschill1290]

Well, I have a Nvidia GeForce 7300 GT from BFG and my problem is when I play most of the games I have, there are either shards and spikes of solid color coming from everything, or there are holes in textures, mostly at the points where things hinge (such as body joints or door hinges). Anyone have any advice? PM me if you think you can help.

Thanks, Chris
