I just got all the parts for a new build, except the case, which comes Wednesday. I figured I'd breadboard it to see if everything runs okay. So I took everything I needed, installed the CPU (i5 3750k) Stock fan, (I bought an aftermarket one but I don't need it atm) 2x4GB G.Skill Ripjaws 1600 RAM (In slots A1 and B1), GIGABYTE GTX660 Graphics card, then plugged in the fan power, motherboard power, CPU supplementary power, and video card power. I plugged in my monitor to the Motherboard's D-SUB port, and my keyboard into the PS/2. (I thought the monitor was supposed to go in the video card, but there was no D-SUB on the card.) So it worked the first time, then I powered it down. The next time I turned it on I got an 'A2' error on the motherboard, and the monitor never got output. I removed the video card, booted up again, and everything worked perfectly. I checked on the UEFI, and every component was detected with no errors. After looking around on the internet for a while, I went back to the UEFI/Advanced/North Bridge Configuration and changed PCIE2 link speed (The port where the video card would be) to Gen3. Now when I boot with the video card I still get no screen output, but Dr.Debug tells me 'ab', meaning 'Setup input wait'. My problem there is that pressing delete or F1 doesn't take me to the UEFI screen like it normally does. Help?
