Answers :

The fan is drawing too much current from the motherboard causing the power supply to go into protection mode. Try replacing the fan with a new one and see this this does not fix the start up problem. You should check out your power supply and see if it really delivers enough power to power all the devices in your computer. The power supply could have weaken due to overheating and aging.
