When describing a fault with words , you have to be really careful to make sure even your mother can understand what your getting at......rereading several times before posting sometimes helps.......I,... like DM am finding it hard to understand exactly what you THINK is the problem!
I own this board myself (Ver2) and once had a hiccup with the Bios.....The fix!......bios FG is now available on the Gigabyte website and seems to be stable as, flash your bios and reboot, load optimized defaults and reboot, change all the parameters you need to suit your hardware back to it's original state and reboot again and go to Windows to verify everything is OK,....reboot and see if there's any changes to the problem you had before, ...at the least this will take several guesses out of the fault finding mission.
