So I just built a new system, I'm pretty sure everything is correct, but it still won't boot.

I have the i7 6700K,
Asus z170 AR motherboard (which has a tool that ensures cpu is placed right.
16 GB of Hyper X Fury Black ddr4
A gigabyte windforce 580
My psu is an evga 750 supernova (80+ gold)

I'm really worried I've broken something major, but as I said the motherboard led comes on, any suggestions?
