I built a pc and it freezes when I am watching twitch streams for a while. It happens only when the hardware acceleration it turned on. Also so far it happend only when I had more than one stream playing.It also happend after a few minutes of playing call of duty. Screen is still showing and fans are running but everything is nonresponsive so I have to do a hard reboot. CPU temperatures seem to be normal. I updated all drivers and I reinstalled windows.
