I just put together a Ryzen 7 2700x on a Gigabyte B450m DS3H, Corsaire Vengeance LPX 3200mhz 2x8gb, with a PowerColor Radeon AXRX 570 4GB, and a 650w Cooler Master PSU. Everything went smooth until I powered it on. Nothing happened. Went over all the connections multiple times, still nothing. I'm thinking the PSU is bad. I switch to my old 600w one I have, same thing. I went over every step to troubleshoot, and got to the point where I removed the GPU. It boots, but gives me the 1 long beep and 2 short beeps, which I found is related to video, or lack of since the GPU is not connected. All fans work, CPU sounds like it is doing something, but no video. So I figured it is the GPU. Swapped it with my old GTX 760 and the same happens. Can't figure out why it will not power on with the GPU connected. Need help fast!
