Hi today i turn my pc on and went away from him for a few minutes when i came back i found massage Bios is updating. So i looked at the internet and found the Bios updates take about 30min so i waited now it is something about 3 hours and still nothing. Is it safe to turn off? or shoud i wait a bit longer. My Motherboard is ASUS CROSSHAIR VI HERO Thank you for answer.
