When i press delete and go to my bios it just freezes all I can see is the Gigabyte Dual Bios title at the top and nothing else. Every feature of the bios freezes keyboard and mouse will not work on q-flash for example. I want to update my bios however when I run the exe file for the update it tells me I need 64 bit file. I cannot find the 64 bit file for the F19g or F18 bios update for Gigabyte Z77 D3h on windows 7 professional 64 bit please help thanks
