I was wondering if anyone here was using ASUS Z77 Sabertooth with the newest BIOS? I had this PC for a while now without any issues, lock ups, BSODs, freezes, etc. Once I upgrade my BIOS to any version above 1403 - my PC begins to restart during heavy CPU usage and I get a BIOS message that my CPU overheated after a reboot. I do have stock-cooled Intel i7 3770 3.4Ghz @ 4.3Ghz, but it works fine with older BIOS and overheats with the newer BIOS. Is that likely to just be a BIOS issue or a CPU issue? Prime95 shows no errors with either BIOS, but with the newer one PC just restarts during Prime95 usage.
I also disabled all fan controls in BIOS to force maximum fan speed at all times since I only use stock cooling.
