I have a Nvidia Geforce4 ti4600 Video card, and i dont think i have the right drivers for the card. Whenever i try to play a 3-d game, it always freezes/crashes when it gets to pretty much anything that 3-D (for example C&C Generals it works fine until the main screen most likely due to the 3-D scene in the background)

if anyone can help me that would be great thanks :)

Try nVidia for updated drivers.
