Acer Predator 21X review
Hope you can help.
I'm running Vista Home Premium, and have had problems with AVG 8.0 Firewall recently, and have been following advice from their technical support team to resolve a driver conflict.
Problem is, removing some of the files they've suggested has stopped my DVD drive from working! Vista Device Manager is detecting the drive, and indicates that I have the most up-to-date version of the driver installed, but shows an error under Device Status:
"Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)"
I've tried using Restore Points to correct the error, with no success, and I've manually replaced the driver files in their original location, again with no success.
Somebody please help...
Virtually all CDs /DVDs players and writers will use the same windows drivers. they are in the windows\system32\dirvers\ or windows\system32\DRIVERS \ folder and are:-
and in the windows\system32 folder
try device manager update driver and install these files. to get your CD/DVD working again.
Another option for you;
Though not strictly your problem,though this may help if you run the Doug Knox fix first and then update the driver.
Missing cd/dvd drives can be normally associated with the removal of burning software such as Nero/Roxio/Sonic/Easy CD Creator etc.

4. Expand the "SYSTEM" Key
5. Expand the "CurrentControlSet" Key
6. Expand the "Control" Key
7. Expand the "Class" Key
