Sometimes motherboards turn the system off when it thinks that the CPU fan is faulty or missing - so try this ...
1 - check that the cpu fan power cable is connected to the 'cpu fan' connector on the motherboard, not the system fan connector.
2 - remove the cpu fan power cable and then re-connect it in case it had a bad contact. Sometimes, excessive dust on the terminals can cause a problem so make sure the connector looks pretty clean.
