Have you guys checked out all the hibernation/sleep settings and just turned them off? Was the inside dirty and/or dusty? Temp monitor? May have had excess heat that was causing glitches with the GPU
all those settings are off, duh not my first rodeo first thing we checked. He has heat sensors on his tower but i dunno if it checks his monitor temp... also he was looking at reviews on this monitor and this is an issue it had its almost 8 years old.
