Please help. I soent 7 hours on the phone today with microsoft and dell with no fix for probelm. windows auto updated to service pack 3 and i lost access to my cd and dvd-rw drives. I already tried the microsftfix #314060 with the tech over the phone. This did not work nor did updating drivers or uninstalling/reinstalling affected drives. Bios for my dell 8400 desktop seems to not show drives and all of sudden my computer is staring up funny showing the an "a" drive floppy which i do not have installed. Does anyone have any ideas on how to fix this problem. I would appreciate any and all advice?
