I had the same situation with my DH77DF after update 0095 BIOS. I tried a USB thumb BIOS recovery, but did not fix the problem yet. Now I am trying take off the battery and release CMOS.
Did you find a solution for the DH77DF problem? My update to 0095 didn't even run (just rebootet after the windows installer said it would reboot the pc to install the bios) and the board doesn't work after that anymore. I cannot even try the recovery option since the screen stays in standby mode. 
I'm having the EXACT same problem. Except, I can't even recover it after removing CMOS battery, memory, jumper. Monitor stays in standby mode. I can do absolutely nothing. I'm sitting here with a huge, expensive paper weight.
I "fixed" my DH77DF by getting a new one from my retailer. The advise from the intel support was: don't use the windows bios upgrade tool, use the F7 method.
Good advice Thedoc!! Updating via windows is waaayyyy to risky, I don't know why any m/b manufacturer offers this method. Use bios utility or pure dos only.
