Optical drives mysteriously unfunctional

I've been running this homebuilt computer for months and all of a sudden the drivers for both my optical drives became non-functional. No error messages of any sort. Just useless DVD drives and big yellow alerts next to my the drivers in device manager. I tried updating the drivers, and uninstalling them complete and reinstalling them as well as running virus and spyware scans. The same problem occurs. Looking at software I recently installed the only thing was the DivX player, I doubt that would cause this. Anyone else have any ideas?
