I have recently installed a DZ77GAL-70K with an I7-3770 and G.Skill Ares F3-1866C10D-16GAB (2 x 8GB)
I am able to successfully boot into BIOS and update BIOS to version 63 but I am unable to boot from either a HDD, USB, or Optical Drive. The PC will recognize the devices but when I hit F10 and tell it to boot I end up with a black screen with no action.
I am still able to update BIOS via USB but I can't even load Memtest86+ with either usb or disc.
I have swapped the memory with another build and that seems to work fine as well as all the other components.
I even sent the board back after talking an hour with Intel support but I have found the same issue with my replacement.
I have removed the CMOS and tried recovering BIOS a couple of times now.
I have disabled UEFI boot in hopes that would help.
I have decided to keep the RAM at default speeds for now until I am able to at least get Memtest86 working on this build.
I read about the issue with the HDMI cable being the issue so I plugged my video card which seems to work find but I still can't seem to boot from another device.
