I built a new Skylake system for my dad (we bought the parts a long time ago) and it won't post. Everything is connected and all fans spin. I tested it with 2 hard drives, I've removed one of the ram sticks and changed the configuration around, I've tried using the HD graphics HDMI port, and I've changed SATA ports. The ram sticks didn't go all the way in at first even after a lot of force, so I just used the one that went all the way in. The GPU fans spin up and turn off like they are supposed to in low power situation.The motherboard is the ASRock Motherboard Mini ITX DDR4 LGA 1151 H110M-ITX/AC and the ram is Ballistix Sport LT 16GB Kit (8GBx2) DDR4 2400 MT/s. The hard drive is Hitachi and the other one I tried it barracuda. Both work in my main system without error. They do have stuff on them, could that mess anything up??
