Driver Error/Drive Not Being Recognized

Well, my XP PC isn't recognizing any of my CD drives, and I checked the Device Manager, and there was the little Yellow Circle thing with an explanation point in the middle.

I uninstalled them and then restarted my computer, and hit update, but still nothing.

Anybody have anything I can do, like registrar edits or something? Tutorials would be great, cuz idk wtf I'm doing.

Thanks
