GEFORCE 3 AND OPENGL AND HALFLIFE!

god jeebus damn this is really pissing me off…i juss bought myself a geforce 3 and i cannot use opengl with halflife…i have tried everything renaming nvopengl.dll to opengl32.dll and placing it in every folder i can think of…i keep getting the opengl mode is not supported by your video card! IF ANYBODY KNOWS HOW TO FIX THIS PLEASE TELL ME IT WOULD BE GREATLY APPRECIATED

Perhaps another instance of DVA=0 in win.ini?
