opengl subsytem error

i try to run a game and but cant because i get an error saying that it cant find the opengl subsystem… anyone now any fixes for this

You are obviously trying to play a game built on most likely the id Software Quake III Arena engine, am i close? YOU do not have a video card, or video card drivers that support OpenGL, I have recently replaced an ATI card with an old 3Dfx card. to solve this issue.
