So I got a new i5 6600k, 8gb G. Skill DDR4 V series RAM, and the ASRock Pro4s for Christmas. Upon building, everything powered on, fans spun, but nothing came out of the onboard graphics, and after a lot of testing, I returned the Motherboard. I just got a gigabyte UD3, and now nothing powers on, no lights, no fans spin. I took out the PSU and tried shorting, (green wire to black on the 24 pin) and the fans connected spun. Could it be another bad motherboard, a semi broken PSU, or something else?
