CHeck the cable on the monitor,,
sounds like a broken wire in the harness to me,,
common problem ,, caused by pushing the PC too close to the wall and bending the adaptor,,,
try a different monitor on it if you have access to one, but dont shove it into the wall,,
the message usually reads " Display Signal Out Of Range" if no feed from the card is being received = Broken wire
