hi, i just installed a new motherboard, along with the intel i7 2600k but forsome odd reason when i start up the computer it does not recognize it, i get a blank screen until the windows 7 user name login screen appears, so im not able to access the bios unless i plug in the hdmi cable into my discrete Gcard, how do i get it to recognize the integrated graphics from startup. When i check the bios screen (with my discrete graphics) i enable onboard graphics regardless of my PEG, so its always on, so how can i fix this?
