Not sure what's going on.

I have flashed my 32GB thumbdrive in an attempt to boot my 8x 1070 on ASRock motherboard to smOS. However, the miner will not boot. The thumbdrive LED flashes when it was being copied to, but when plugged into the H110 motherboard, there are no lights so it seems that the thumbdrive itself is not booting. Please help!

While running my 6x GTX 1070 rig, the powerline in Afterburner bounces up and down like crazy, it is not steady. I am running (1) 650W and (1) 650W psu. Can anyone help? Thanks!
