I've breadboarded and tried a new PSU, RAM, installed a GPU, tested the CPU header with a multi meter, and nothing is making sense. Plugged CPU fan into system fan header and it spins but BiOS wont let PC boot unless CPU header has fan running on it. Any help is MUCH appreciated.
 
Solution
Connect some case fan to CPU_FAN header to see if header works. If the fan will not spin, you have faulty header (and most likely need new motherboard in this case).
