So I go to play Halo reach and stream it to twitch. About five minutes into an online match, my screen goes black. PC is still on but nothing is happening.. CPU fan set to turbo. GPU fans set to auto. So I am having to force shut off the PC and turn it back on. This does not happen when I go play rocket league and stream it.. Only with Halo Reach.. What in the world is going on with this thing??
