CD Rom drive implies a very old PC as most modern PC's have DVD drives.
does drive say DVD or CD on front ?
CD & DVD drives do not need a special driver under Windows (except for XP to write to DVD-R or DVD+R optical disks)
Problems include dust in side, hardware faults, disconnected cables and corrupt registry (upper filter/lower filter drivers)
Sometimes Windows says Insert a disk, sometimes Windows detects disk but will not show anything on disk.
Also does BIOS report presence of optical disk ? (if not electronics fault or cable problem)
we need some more information about your problem to be able to help you
If you can start up your PC from a Windows XP or 2000 CD or Windows Vista or 7 DVD problem is likely to be registry corruption
