G'day everybody. I have recently become the proud owner of GA-X79-UD5 in a Custom Build. I made my first foray into the BIOS to switch off Hyperthreading which is widely advocated for Flight Sim using FSX. I did not touch or change anything else. I pressed F10 (Save and Exit) and the machine closed down and will not reboot.
I read an active thread along similar lines, but in my case I can not even get started because I do not know where the Battery is. Perhaps it is marked on an image of this MB somewhere? Help please, thanks, Mac
