I have a gigabyte ga-970a-ud3 rev 1.2 motherboard running on 8.1. Since updating to 8.1 I cant change a single thing in the bios without my computer failing to boot. I'm thinking this motherboard is too old and maybe just need a new one. There has not been an update for the bios since 2012. Is it time to upgrade or is there something im missing here? Thanks!
