I own an Intel H55/H57 deries motherboard with an LGA 1556 socket and an American Megatrends BIOS. For some reason it only boots on my IGD, even if I reset my BIOS settings. It completely ignores the fact that I have specifically chosen PEG/PCI in the settings. I know there is nothing wrong with my Graphic Card as sometimes, my PC boots on it. But if I Restart it or if it Shuts down, the next boot is on IGD. The frequency of PCI boots has decreased significantly, and now it has been 3 weeks since that last happened. This problem started several months after I changed my motherboard. If there is any way I can fix this, I would like to know. Any addition information needed to fix this problem can be provided. Thank you.
