PC fails to start despite connecting the 3PIN LED to the motherboard.
I assembled a new PC last month and am facing boot problems. The 3-PIN LED connected to the motherboard via the hub/fan controller isn’t working. My case fan activates right away when the PSU starts, but the PC won’t power on or start after I press the power button. Removing the 3-pin RGB header from the board lets the PC boot normally, but now there’s no RGB lighting in the fan. The issue seems linked to the motherboard and fan hub setup. After swapping the fan hub/controller, the same problem persists. Please check connections and ensure all components are properly seated. If needed, share more images for better diagnosis.
