Heyyy what's up , what did you do to make you pc work ? I have the same issue
I was moving some cables inside my pc, and when I went to turn in on, I was met by just a flashing white Aorus logo on the motherboard and no other sign of life (power button not working). After waiting a couple hours, the motherboard now has rgb lighting but shows a red CPU status led and still no power button. I would appreciate some help.
