My cd/dvd drive is not showing up on "My Computer." The cd/dvd drive entry on the Device Manager is also missing. I tried several solutions I found online but none of them worked. Microsoft Fixit didn't work and deleting the upper and lower filters in the registry didn't work. Since it doesn't show up on Device Manager I can't reinstall the driver. It does show up on BIOS though. It also has power. I can open up the tray and the light turns on and the drive makes noise when I put a disk in. My computer is running Windows Vista. I'm not sure of the make and model of the drive. Please help.
