Right click on the My Computer Icon on your desktop
and select Manage and select: Device Manager
(Or: Go to Start, then select 'Run' and in the Open field enter: devmgmt.msc
then click on the OK button)
After the Device Manager window opens, click the "+" to expand the
DVD/CD-Rom drives option.
Next, right-click on the CD/DVD Drive(s) you are having problems with
and select: Uninstall.
You may be prompted to reboot your computer, do not reboot!
Instead shutdown the PC and remove the cable to the CD/DVD
drive or drives. Now with the drives disconnected, boot the PC.
Check that the CD/DVD devices are no longer listed in
Device Manager. Now power down the PC, reconnect your
CD/DVD drivers. Windows should discover the devices and
reinstall the drivers.
