Hi,
I have the H77N-WIFI Board, built my new machine back in January this year and up until now have had absolutely no issues with it. Yesterday when I switched it on last night and it did not boot into Windows 8.1, instead showing me a recovery screen with he message "Boot Configuration Data file missing required information" After this the computer was totally unresponsive, couldn't ctrl alt del so did a reset. Tried inserting the windows 8 disk but system will not boot from the disk, and hitting F12 doesn't let me into the bios menu. After several attempts at resetting the system stopped showing the windows recovery screen. It would get as far as showing the gigabyte boot menu and then hang, after a while the screen goes blank and it stays like this. Sound like the board has an issue, given that it wont even let me into the bios or boot from the original windows disk. any ideas???
