So windows boots up fine. It was stable for 12 hours doing regular stuff. I played day z standalone for 4 hours with no issues. Today I try playing ARK / World of Tanks / Battlefield Bad Company 2, and after a few minutes, the monitor goes into standby and says "The refresh rate is not supported by your monitor" and I can't do anything but restart. I try alt tabbing and alt f4 to close the game but nothing happens. Im running a "high speed" hdmi cable until my display port cable arrives. specs: i7 6700k evga 980ti 16gb ram dell u3011 850watt psu Any ideas?
