I recently built a PC about a month and a half ago. Although the build took longer than I wanted, it booted on my first attempt and there were no problems with it. Have been playing smoothly until now. Today, I went to turn it on and all the rgb lighting lights up inside the pc, but my keyboard (connected to usb port on i/o panel) does not light up unless the pc is on (when working it would glow even when the pc was off) and I get "no signal" when booting on my monitor. Display port is plugged into GPU, NOT motherboard. Have tried other cables. Took off back panel. Swapped the RAM to single, back to dual channel. Took out GPU and put it back in. Still nothing, any help is appreciated! I feel like it may be a problem with my motherboard or cpu, but I'm really not sure.
