opengl and counter-strike

I am trying to get OpenGL configured so I can play counter-strike. When I go to the configuration>video>modes menu, I click on OpenGL and select default. When I connect to a server, it says “your video card does not support this opengl mode”. But I can still connect to a server…and I have good fps and stuff it is just really blurry.

I have a 64MB DDR NVIDIA GeForce4 Ti 4200, and I tried installing the nvidia driver for it but it says “warning has not been microsoft logo tested for xp” or something like that. I click continue anyways, and it just freezes up…

I am a really big newbie when it comes to stuff like this…Any help would be appreciated.
