did you check to see if you were on latest bios?
My motherboard does not have any BIOS updates released for it. It's relatively new, made in 2014. I checked Gigabyte's website for my motherboard, but there's no new BIOS version. Even if there was, I'm very scared of re-flashing my BIOS due to me doing it once to another mobo and it ended up bricking the whole thing.
