I built new PC with Ryzen 2700 and GIGABYTE X470 AORUS ULTRA GAMING.
Yesterday it was storm so I decided to unplug PC from the wall. In the morning when I pluged it back in it wouldn't boot (CPU led was on, then for half a second DRAM led blinked and then again CPU led was on). I don't know where the problem was but I found on some forum that MBO has backup bios option to restore old bios (I upgraded from F2 to F3g) i have to hold reset button and power button for 20sec. After that it did some stuff and it was working again I could normally boot into windows no problems. Curently I'm selling my old PC and I needed PSU cabel so I unplugged it again couple hours ago. After that same story happened. Why is my bios getting boot error after power loss, is there any chance of fixing it or should I request new MBO?
