Just built a new computer with a new ASRock z270 extreme 4, a new Corsair 850 way, a new iCORE 7 unlocked, and new Corsair vengeance DDR4 2x8gb ram. So the motherboard lights up, but when I go to turn it on the fans don’t spin (PSU, case fans, CPU fan.. none of them) and the computer doesn’t boot. I’ve checked the connectors several times. I also took out the PSU and plugged it in to another computer and it works just fine since that was my first suspect. Needless to say I’m assuming it’s the motherboard itself, however any other opinions would be great. I’m about to take everything out and do a complete reinstall though my hopes it’ll miraculously change something are slim. Any thoughts?
