When I play games I randomly freeze and I can't do anything to quit what ever game I am playing, which forces me to shut down my PC by holding down the power button. When I turn on my PC I get a BSOD saying a required device isn't connected. This error happened to me before and the only way I fixed it was to shutdown my power and wait a couple of hours, when I open my PC it works and everything is normal, except this time... my PC froze while I was playing Diablo 3 and I force shut it but it reboots to the BSOD. Any suggestions on what to do?
