You can check your psu by shorting two wires but it would be useless for you as your psu is working for some time.. I suggest you one method don't know it would work or not:
At first disconnect all SMPS connectors from mother board and other peripheral devices like DVD RW, HDD etc. Now switch on the mains and short two wires. One is GREEN and another is BLACK. If the SMPS is in working condition it will start.. You can short them by taking a piece of copper wire..
Keep it for sometime.. See whether after sometime the psu fan is working or not.. if not then may be its the confirmatory..
