So I have been putting together my gaming pc for about 2 days now just coming into contact with this problem. I have looked at just about every solution and I'm currently sitting with my motherboard outside my case and I've powered it on twice, (with just the CPU, cooler, and 1 stick of RAM) both times with that message. I checked the USB ports and none of them seem to be damaged, pins are intact and I'm starting to think it's my mobo. Could it be the USB ports on my motherboard that are shorting out?
