My Computer - the DVD drive doesn't show
Tried:
- another DVD drive - still doesn't show
- Device Manager has a yellow ! next to HL-DT-ST DVD RW GWA-4080N
[Windows can not start this hardware device because its configuration information (in the registry) is incomplete or damaged (code 19)]
- MS online repair - no change
- uninstalled, rebooted - installed - no change
- last known good configuration - no change
- restore to Jan 4 2011 - no change

- fresh Windows install with alternative hard drive - worked, read from the DVD drive to install windows, My Computer reflects it

Is there anyway to fix the current drive without having to do a backup reinstall so the DVD shows and works? 		NZHawk (4093)

5. In the System folder, double-click the CurrentControlSet folder.
6. In the CurrentControlSet folder, double-click the Control folder.
