So I was remodeling my room and moved my desk to the other side of the room. I connected the Ethernet to my computer and powered it up. The Ethernet light didn’t come on and one of the fans didn’t turn on. I connected my keyboard (which is RGB) and it lit up. After that I connected my mouse, which lit up for 1 second and then it turned off. Is my motherboard half dead? Or is it something else in my computer which is causing this problem. FYI I bought a new Ethernet cable and connected it to my computer before powering it up.
