DVD ROM problems

[Demon Cleaner]

My PC is trying to make me destroy it, as it gives me weird errors/problems lately. This time it are my DVD drives again, not that they won't read RW discs like last time, but they are no more recognized by Windows.

I wanted to burn a DVD now, but it seems my drives are gone. In the Device Manager they are listed with problems. So I tried to restart the PC, entered BIOS, where they are detected properly, booted to Windows, but nothing has changed. They are even not visible in Windows Explorer anymore.

It are surely not the cables, I controlled them, and they are correctly recognized in the BIOS. Also they are connected to different IDE controllers.

Anyone an idea? This makes me mad, as lately I have many problems with my PC, and only such unexplainable ones.

EDIT: Ok, problem solved. I deleted the LowerFilters value registry entry, rebooted, and it works again now, don't know why this happened though
