Hey guys I recently (within the last week) built a new computer and it has been rebooting and freezing on me whenever I try to use youtube or play games on steam.There have been no BSOD, the computer just freezes requiring a hard reset, or it will reboot itself. I have already run several stress tests including: Heavyload, Furmark, and Prime95. The computer did not crash during any of these tests. In addition I have been monitoring hardware temperatures using SpeedFan, so I do not suspect the freezing is due to overheating.
