hey
If not visible at all there may be a hardware problem
turn off the computer
unplug everything, leave only keyboard mouse, and monitor
disconnect the power plug from the computer.
hold down the power button for a while
open the computer, unplug the dvd player, check the cables if not damaged
then reboot!
Once the computer has started up, turn it off again.
Repeat what I said at the beginning, and reconnect the dvd player, then restart!
if nothing probably faulty
