I noticed everyone seems to be of the opinion it is hardware related, in my opinion hardware errors are accompanied by the BSOD. I haven't had a single one. Mine freezes and mouse still active for a minute then it freezes also and another minute or two and it reboots. These are the Hallmark of windows system crashes, or time outs. Nobody has changed hardware and fixed it right?
Funny you mention that, I had my first BSOD last night when it crashed.. looked like so..
That weirdness is the ingame menu for Star Citizen.
