I bought a asus x99-e motherboard so I could move my intel i7-5820k into it from my previous motherboard. I moved the motherboard into a nzxt h500 as well and when I started everything up and the motherboard showed a red light for the cpu but everything worked except for the USB ports. Anyone know why?
