Computer not picking up dvd burner

[EliteForces]

Hey i have a dvd burner which was working fine and was being picked up no problem but now my computer just wont pick it up. Not in bios, not in windows or anything. I checked the cables and everything is fine jumpers are set properly. Can anyone help me with this?

Try a new set of cables. Also, try it in another system - if this doesnt work, its probably dead.
