IT almost sounds if the monitor itself is overheating? Have you tried shutting the monitor off for 15 or so minutes then turning it back on? It may also be a video card overheating issue. Make sure your PC and Monitor both have adequate ventilation.
IF this doesn't help the situation, try updating the video drivers as well.
