I just bought a new computer. It came with two drives. A CD drive, and a DVD drive. These drives were working when I first recieved the computer, and for a time afterwards. However recently both drives are not being recognized by the computer. I insert a disc, it doesn't run in the drive, and when I try to open an application that runs with the disc the computer replies with a message saying "no CD/DVD drive found on this computer".

I have tried uninstalling and reinstallin the drives, however that doesn't work. I have checked connections and software, everything is fine. I need help on this because I have no idea what the problem is.
 
The upper and lower filters in the registry are corrupt. Delete them and reboot the computer. They'll be back after that.

It worked!
Click to expand...


Did you ever have any doubts? :P It's what I do for a living. I just don't often have time to do tutorials (thanks much to Stranglehold for stepping in), so I depend on people to use Google, as that's what it's there for. I just usually point people in the right direction (unless, of course, they're paying me... lol).
