I have an Alienware Aurora laptop. The machine is powered (LEDs lit, drive spinning) but no POST. None of the 4 fans spin at all. The screen doesn't show anything and the computer reboots. Upon internal inspection I saw the fan above the RAM has a wire that is no longer soddered. So that fan is dead for sure but the other 3 should be good.
Could this 1 non-working fan potentially prevent the whole system from booting? The model is prone to overheating.
Or are these just signs of a much bigger problem like a CPU or mobo?
