Old Graphics Card.. Cant find new driver

I have a really old computer. it is a Dell XPS T500. I bought it in 1999. My new games dont work on it because it dosent have opengl. i have been to the manufactors website and they have no new driver. i think it might be too old but i have know i deal what to do. If any one knows how to fix it e-mail it shenswimmer1@aol.com

What graphics card does it have?

Also, if you are trying to play modern games like Doom3, then forget it. You need something no older than 2 years.
