Okay- I have experienced alot of lockups and most of the time you never know what the problem is. I may even be blamming this on the wrong piece of hardware, but I have heard that Sound Blaster makes damn good hardware but have very hard time writing good drivers for there own hardware; how sad! I think it's true; I'm thinking of replacing my sound card; any suggestions? Reasons: I play Nascar and it uses Direct Sound; I tried turning off Direct Sound in DxDiag and didn't get any sound at all. Also if I turn the channels above 8 I see major difference in FPS; why? Does anyone else out there have any problems that may relate to mine?
