in OpenGL mode my comp crashes while loading counter-strike

I just recently downloaded the most current version of OpenGL for my Voodoo3 2000. I heard that it would make the game run much smoother. I went into the game and switched from direct3d to opengl. Then as the game started to laod up my computer crashed. It would just sit there. The busy light was off and I couldn’t make anything happen. After a few minutes of this I pushed alt+ctrl=del and it said the system was busy and to push any keep to continue. I pushed enter and then the power light on the terminal went out. Nothing responded at this point. I had to cut the power, reboot and play in D3D mode. If opengl is in fact better and will make a difference in my fps then i would like to get some help and give it another try.
