Have you looked for any conflicts in the Hardware Manager?
This can cause DVD players not to be recognised.
It is often worthwhile removing all players
from the Hardware Manager and allowing Windows to re-install them on a cold reboot.
This is sometimes more effective if they are removed in Safe Mode.


I have had the same issue before. Its something to do with the registry.

and this is the reg fix need ,it may or may not be the fix!!!
Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)

Possible Solution......go to Start /run/ type in ,regedit.and do the following

There are 2 reg keys that can screw the device......remove them both and reboot......

The keys are:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325 -11CE-BFC1-08002BE10318} - "Upperfilters" and "Lowerfilters".
