Hey everyone, I own a B550 UD AC motherboard and recently noticed something odd. After restarting my PC and playing normally, around 35 minutes in, I saw a steady red light on just one side of the board. It wasn’t flashing or blinking—it was just there. I checked it out online and found it’s a QFLED LED. I tried updating the BIOS, cleaning the ports, and doing a full PC clean, but the light stayed on. Even when I power on the PC directly from the PSU button, the red light appears instantly. 20230514_001215.jpg
