I have had a Physx card for a year or so now, and it worked great. A while ago i put a new 1TB hard drive in and reloaded Vista (and everything else), but left my card in whilst i did this. I now dont get any option for turning my physx on on the nvidia app. I can using my 8800, but not my physx card. I have tried removing it and putting it back in, and tried different ports, but still no good. I'm sure its because i left it in when loading vista up, and its not recognised now for some reason. It isnt even in device manager, as if it isnt even connected. I dont have the luxury of testing it in another PC unfortunately.
