I'm having issues that I can't quite solve and I have to reach out for help. I recently rebuilt my pc with a gigabyte ga h77m d3h and core i3 2120 with 512m dedicated to on board graphics. The computer will start fine after you do the fresh install of windows 7 prof. 64 bit with the default video driver from windows. I've updated my bios using gigabyte's @bios tool and I've tried installing th drivers from the disc, from intel's website and with automatic update in device manager. Could a corrupt windows install file cause this issue? I downloaded the ISO from the Microsoft website when I bought the product key. Is there anything else that could be causing this issue? Please respond if there's anything you can think of.
