[QUOTE=DeltaRay;2429853]So… You probably have either Nero, Roxio or ITunes installed?
Click on Start, type regedit, then right-click the regedit.exe file that shows up
at the top of the windows and choose “Run as Administrator”.
Open HKEY_LOCAL_MACHINE, SYSTEM, CurrentControlSet, Control, Class
Go to the first key with the following name:
It should say “DVD/CD-ROM drives” behind (standard)
Then right-click the “UpperFilters” key and delete
also delete the “LowerFilters” key if it exists…
Close regedit and reboot your machine…
Everything should be fine now!
[B]Should I use this procedure to fix my problem??[/B]
I have had the Optiarc DVD RW AD-7190A ATA installed (it came with the PC) and working until today. After uninstalling an apparently unrelated program the hardware no longer runs when a CD or DVD is placed in the drive. It is as if the hardware is not installed or else not talking to the PC. Is this a driver problem or have I managed to somehow uninstall the hardware?
I’m at a loss as I can’t load anything without a CD/DVD player but I’m also concerned 'cos trying to delete the upper and lower filters causes a pop-up that warns of possible system instability.
