CD and DVD missing?

[Gronkalonka]

Hmmm...Don't know if I'm posting this thread in the right place, but anyway... A week or so ago, my CD-burner and DVDrom reader went missing. I can't find them on "My computer" and all the drivers are gone. I can open them physically, and I can hear the driver read the content of a cd/dvd , but I have no way of opening/burning/reading a cd.

So now I'm a little confused. I used ad-aware, spybot search&destroy and Norton antivirus (+norton internet security) 2004. They're all up-to-date, and they didn't find anything.

I also tried to switching the IDE-cables, removing the powercables, removing the drives and putting them back in, without any result. I would format the computer, but I don't know if I'll be able to re-install windows and the other stuff, as I don't know if the drivers will work.

I'm really stuck, I don't know what to do. The computer is fairly new, running on Windows Xp. I've never had any problem with it until now. I would be so grateful for any help...so please... HELP!!
