RGB not working for AIO and case Fans?????

Help? RGB not working

I bought a prebuilt. The rgb has worked and one day it just didn't work. I've had the pc about a week. Everything physically works, fans spin, AIO works.

The RAM lights up but the AIO and case fans do not. I have checked that it's ARGB and not RGB to make sure i hadnt fried them because of the voltage difference. I've made sure the ARGB plug is connected on the motherboard.

Taking off the metal back panel I have checked more LED plugs and everything seems to be in correctly.

I don't know what's wrong.
