DVD-RW and DVD ROM Failure

Recently my DVD-RW and DVD-ROM dirves disappeared from my computer. They were both working fine one day and the next day the computer could no linger see the drives.

Device Manager indicates Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)

Click Troubleshoot to start the troubleshooter for this device.

When I uninstall and then use the Add New Hardware Wizard to reinstall the Plug and Play devices the problem persists.

Is there anything else that i can do to recove the use of the DVD-RW and DVD-ROM drives.
