Pioneer 215DBK not reading dvds/games or appearing in device manager

[Nivforever]

Since this morning my Pioneer 215DBK will no longer run dvds or games, it's no longer in device manager either. I checked inside the machine and everything appears to be connected properly. When I put a dvd into the drive I can hear it loading but then it just suddenly stops, it doesnt appear in my computer either. I'm running vista premium 64

Any help would be appreciated

Thanks

Since you checked the cables i'll ask another question ...
How old is the drive ? ?
They aren't made like they used to be.
The best way to test a CD/DVD drive is to swap it in to another working machine to see if it has failed. Takes about 10 - 15 minutes...
