When I play games my pc freezes after a few minutes. Won't be able to close out of the game or anything, so have to turn it off by holding down the power button... Then when I power it on again the the fans spin, lights turn on and everything, but the monitors don't turn on, so I have to shut it down and turn it back on again in order to work properly... This happens every time after playing games for 15 minutes or so... I updated the drivers btw. Pls help ((((((
