I'm using an ASUS p8z77 V premium mobo and am currently trying to get a hard boot to see if BIOS screen is up and running. I believe that I have all necessary wires connected to mobo for this to work...however in my infinite wisdom, I bent one of the pins that accepts the cpu...It looked like only 1 pin was bent so I corrected as best as possible and it looks OK. I have the 24 pin power connector cable installed, HDMI out is connected as well, RAM, CPU are all in...It is ivy bridge cpu so it has integrated graphics.
