I am having an issue with my video card in order to play Knights of the Old Republic 2, please help?

I have Windows Vista and have updated my video card however when i scan my hardware to play the game the only thing that does not pass is my video card? How is it that a game that is 5 years old can not run on a computer that a few months new? Also, the game tends to stop working when I click on "Game" from the Launch menu?|||Game requires at the very least a video card with 32MB VRAM. Integrated video is a chip on the motherboard and not a video card.
