This is my very first PC build. Everything is working fine but for some reason the only way I can get my computer to boot is if I only have one stick of RAM inserted. I tried both sticks one at a time and they both work so it's not the sticks. As soon as I try to use both at the same time the computer will power on but it won't display anything on my monitor. I don't know what the problem could be. My motherboard is a ASROCK H170A-X1
