I have gigabyte board with dual bios im running raid 0 on too wd blue drives my motherboard sat for a year in the anti static bag it came in. I updated the bios but it keeps falling after a month or so and reverting back to the original version of bios and when I go to boot is says missing table or something like that. so I update bios again to what the version was before it failed it now says missing os system I don’t know what keeps causing the problem is it my motherboard failing like the battery or something?? Or the raid array failing on me making the bios fail I don’t know what is normal when a raid array fails I used the motherboard before it sat for a year in a non raid system with the original bios and it worked fine
