Yes after a while of playing skyrim my screen freezes during gameplay goes black and says no signal then comes back and i can play the game..Im running 2 graphics cards and 2 monitors...one graphics card is geforce 520GT the other is geforce gt 610..my 520 GT runs hot as hell and lags my minecraft down so i switched to my 610GT as my main..could keeping my 520 hooked uo and connected cause that problem..cause my gt 520 would run at 70-79c when playing minecraft..
