Hi. I have just reformatted the hard drive of a freind,s comp(or at least they were), and reinstalled windows XP pro, everything went surprisingly well apart from now, there is no sound on the pc. There is also no speaker symbol in the sys tray, and if I go in to device manager, there is a small yellow exclamation symbol next to the "C-Media AC97 Audio Device. I have tried uninstalling this and reinstalling it again letting windows look for the drivers etc, etc. Even tried downloading some (drivers) which have been suggested on previous threads of the same problem but nothing works, and still the little yellow icon is there laughing at me. I can see from previous threads, that this has happened to other people, but haven't yet seen a possitive sollution to the problem. Please Help if you can. Thanks & Rgds.
