I'm trying to disable the onboard graphics from my P8H61-M LE so I can enable the GTX 560 I have. I updated the motherboard driver, and now when I go into the bios -> advanced -> advanced -> Graphics configuration -> Primary display
I choose PEG out of Auto, IGFX, PEG or PCI.
When I go F10, save changes and reset, I still get no signal from the video card but I do from the motherboard. If I check the bios again, it shows the default "auto" setting at the graphics configuration.
I have the same problem, even bought the GTX 560 so I could run Skryim and BF3.. Anyway, I suggest calling Asus like I did and maybe you'll get better service..
