Had to fix a similar problem for an end user on his CD-ROM drive which suddenly stopped working and was no longer recognized in My Computer. Turned out to be the Removable Storage service was not running.
Check the CD-ROM drive by opening up My Computer after inserting the disc.
Verify that the CD-ROM drive even shows up in the My Computer window.
Open the Computer Management console and check Removable Storage and Disk Managment nodes under the Storage Tree by highlighting each one to view the contents.
-> Highlight and expand the Removable storage node, highlight Media to see if there is anything recognized there.
-> Highlight the Disk Management node to see if there is any media detected in the CD-ROM drive. By default if there is no media detected, it will say 'no media'.
In the Computer Management console, check the Services node and verify whether or not the Removable Storage service is started and running.
-> Click in the right pane and scroll to highlight the Removable Storage service, right-click and choose Properties from the shortcut list.
-> Once the Properties applet is open, check the Startup Type drop-down list to see if it is set to Manual or Automatic.
-> Start the service (if it is not already started, in the case that it is set to Manual) using the radio buttons in the Service status section.
-> Restart the service if necessary using the hyperlink that is below Removable Storage which will appear under Services near the divider between L and R panes.
-> If the service is not started and you start it manually, go back to My Computer and see if the CD-ROM drive recognizes the media.
