I have the AC 97 built in sound in my intel 810 motherboard. I have to reformat about every 6 months because my system is just ******; too many reasons. However, usually this gets rid of bugs and I am good for quite a while afterword. THIS TIME however, it has remained "stable" for an extended period of time. Only problem is no sound. The driver disk that came with my system is now, mysteriously, useless for a correct sound driver. I have tried driverzone and dl'ed numerous drivers to no avail. I am pretty capable at step-by-step troubleshooting, so I am open to suggestion. You guys (and gals) have helped me before, I am calling on your expert help again. Thank you in advance for even reading this in the first place; Thank You X 10 if you help me out. Yours, a busy fireman in ALABAMA! GENX computer, 866 Pentium III, 256 RAM, 30 GB HD, Intel 810 MoBo.
