Open up device manager and uninstall the dvd/cd driver (do not scan for hardware changes or allow windows to install a driver at this point)
Open up your registry editor and then navigate to the following path.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
First delete the UpperFilters (if any)
Next delete the LowerFilters (if any)
And finally reboot your system and allow Windows to reinstall the driver itself. This should resolve the issue.
It seems as if Windows cache’s the driver that is used for the dvd/cd drivers making an uninstall of the driver with a scan for new hardware absolutely useless. By removing the registry values it seems to remove the cache and tends to start from scratch with a new driver.
