I believe the Intel DG965RY motherboard is the problem as the PSU fan kicks for a second then shuts down. Nothing else seems to be working.
I disconnected the 24 pin connector from the motherboard, shorted the off/on to turn the PSU on, then checked voltage on the Antec PSU. The fan now works & I seem to have all the proper voltages on the connector.
Is there a for sure way of checking the motherboard? It's about 9 years old.
