    DZ77BH-55k post issue with add in PCIe graphics card


      I am having an issue where when using a VGA connection on ATI HD5450 add in graphics card causes system not to post. I can typically get it to post with DVI connection  but then I am getting error code 12 when I do a reboot from windows.  At this point I am not sure if I have faulty
      motherboard or incompatibility of graphics/motherboard. I have other systems with the same configuration working fine, so I think it  might be a motherboard issue.


        Motherboard: Intel DZ77BH-55K bios rev.0099 (using intel toolkit) bios graphics setting set to Auto - tried to force EXT PCIe graphics and same result.


      Graphics Card: Sapphire HD5450 AMD catalyst
      control suite version 13.1 and 13.4 tested with same result.


      Chipset version 9.30.1036

      To get the system up after the reboot lockup, I have to force a restart from front panel button of the chassis and then the system will post and boot into windows. If we use onboard graphics  driver version ( I don’t have any issues with initial boot or restart command from Windows.
