So I flashed my bios to 0803 and start OC from defaults, everything was fine but occasionally, I will still get the reboot when exiting bios.

I was changing the voltages and after around one hour, the 'BEEP' occurs again. It only happens when exiting bios along with the reboot and when I switched off my pc(windows shutting down)

I am running E6600@3.45ghz ram4:5 blend test orthos 8hours last night.

What could be the problem?

Anyone??
