When I try to run Counter Strike 1.6 with OpenGL, the game freezes (along with my entire computer) after about 5 minutes every attempt. This doesn’t happen if I run the game in D3D, but Counter Strike is made to run on OpenGL, so D3D doesn’t give as good frame rates. I’m running a Mobility Radeon 9200. Anyone else had this problem?
Have you tried to update the drivers on your system?
Video drivers, chipset drivers, etc.
