Need help with games

I need to run a game using opengl. I downloaded opengl1.1 and extracted it to both my winnt and my game folder, but it won’t work. What should i do?

You have OpenGL drivers for you graphics card also?

Im not really sure. I have NVIDIA Riva TNT2 M64. But i dont think it supprots opengl. What should i do?

it support openGL.
You must download new divers from nvidia.com(detonator).

I tried and it messed up my system. I downloaded it and run it. then the comp suddenly restarts and i cant access my win2k pro. The screen just stuck there in the starting picture (the window), altough i can hear my windows starting sound. HOW?
