My CD/DVD drives suddinly stopped working, I have tryed to delet Drivers and reinstalle them and i am preaty sure the cords are fine. The Drives wont read a disk. I also tryed to us a Boot disk to wipe the Hard Drive and it dident work so i think it has to do with my BIOS, I might have a vires on it is there a way to get ride of it or check it.
