Quake 3 crashes on me all the time! Help!

It never did this before. I think that the problem may be that I switched my Refreshed Rate from 60 to 85. I have an ATI XPert 2000 and 256Ram on a KDS AV7TF. It could also be an Open-GL problem.

When Quake crashes, does it display any error messages? Did you try setting the refresh rate back to 60Hz. and see if that corrects the problem?

Also, what makes you think it might be an OpenGL problem if it worked previously without any crashes?
