Hi,

There is a possibility that your Intel MotherBoard has got some problem. To confirm the healthiness of your PSU just remove the 24 Pin Connector from the Mother Board & short the Green & Black slots of the 24 Pin connector. (Be careful when you do this). On doing this the PSU should run smoothly, indicating that there is no problem in the PSU.

Also check whether there is a green LED on the MoBo & whether it is ON or not.

I had this same problem in my Intel 915 GAV Mother Board which was replaced by Intel as it was under warranty.
