Counter-Strike problem

I am so with all of you guys on this CS thing - I have a top pf the line GeForce4 Ti 4600 bassAZZ MUDDA FAUKER and it has always played CS fine and dandy … then all of a sudden I try to play CS and I get an error message saying “Your video card does not support OpenGL” ! ! ! BUUUUUULLLLSHHHH***TTT
And then I tried to run another OpenGL program I have called Earthviewer and it says I am missing the file GLU32.DLL … Maybe this could be the dirty problem. But as I look all around the different OpenGL sites, I do not find anywhere I can find just that file!!! And trust me, I am no idiot when it comes to computers and have installed/re-installed CS, my card, drivers … I have made sure every driver was updated from my motherboard to windows, etc!!! Maybe someone could just send us the damn file - Or be a big help and actually tell us what is wrong … all you OpenGL gurus out there …
