so I took it out and I put a ThermalTake Smart Fan in. I plugged it in to the CPU Fan on the motherboard but it does not turn on. When you go to boot up you have to press F2 in order to keep booting. This is also a family computer so it's really bad. There is no option in the BIOS to stop it. I also just put in a new HSF and it still will not give out power and you still have to press F2 because it is getting power directly from the power supply. Is there anything I can do so you don't have to press F2?
