Welcome to bleepingcomputer!
You'll need to get into device manager.
In Windows Vista, just type "device manager" into the search box to bring it up.
In Windows XP, go to start, control panel, system, hardware tab, and click device manager. Once there, go under DVD/CD drives section, and right click on the bad drive. From the list that comes up, click uninstall. Uninstall the drive, then restart your computer. Windows should automatically reinstall the drivers for it.
If this doesn't fix it, and you have another working drive in the computer, I think the drive is probably bad.
