need a little half-life cs help

Hey guys, im new to this forums and I have a question for you gurus. I am a gamer of course and I play CS.

I was wondering how I could download a openGL software to allow me to run openGL instead of Direct 3d for playing CS.

Whenever I choose OpenGL in the video modes then I enter a game, it disconnects and says: Your video card does not support this mode. Then i go back to direct 3d and direct 3d is kind a crappy for my computer.

My specs include:
192 mb ram
590 mhZ
Voodoo 3 graphics card (cannot find patches for windows xp)

k thanks I appreciate this greatly!

damnit im noob. I misseed the gaming related forums. ARGH!!! sorry for wasting your time!!!
