See the hole in the last photo with the metal ring, those are the ones you put standoffs under. It keeps your motherboard from grounding out against the case on the bottom. Hope you havent shorted your board out!
I installed the standoffs and tried running with just cpu power and main mobo power connected and it worked so I redid everything and it turns out that me using a cable coming off the powersupply with a hardrive and fan cable was messing it up
