Hello guys, i am building a new pc so cpu mb everything is completely new, it just stuck with bio is updating, please do not turn off  but it turned off automatically after 5s. i was using a jumper to power on mb, only installed cpu and m.2 and ram, nothing else.

The message is normal. The system will then power cycle as you describe. Check the BIOS revision from within the UEFI.

What board?

thanks for the reply, asus x670e proart creator wifi, it is always shut off by itself in 5-15s after i jump start, and never reboot itself, i tried to jump start every 20mins or so but always last no longer than 15s, is that normal? should i leave it over night and unplug the power cable? 

thx

Did this behaviour start after trying to update the BIOS via EZ Flash? You can try removing the CMOS battery and leaving the system unplugged from the AC for awhile, yes. Then reattempt.
