Bios flashing problem

I just ran into a similar problem with an EP35-DS3P. The bios was corrupted and even though it had dual bios, I ended up having to ship it to them so that they would wipe the data. Their RMA process blows. Not going to lie. Honestly I'm never again using @bios. That program is junk. I am not going to do any flashing from within windows. I'm a bit disappointed in gigabyte that they would even advocate that program. I don't know what to tell you, but I would try flashing to an older bios. If that is still corrupt. You'll probably have to send it in.
