Frequent re-starts while booting - Intel Core i3/i5-2933

[binoymenon]

My system re-starts everytime switch it on. It even re-starts a couple of times even when I give the restart from the OS.

First of all it takes a while for it to power on. Then before RAm/HDD gets detected it restarts. Again it restarts during and after POST. While the OS gets loaded it sometimes restarts again.

Once the system is up and running it works pretty fine.

@ the time of POST the screen sometimes freezes and then gets re-started.

1. Is this a problem with the power supply? Sys. config given below. Its a 1 month old PC.

2. My RAM is supposed to be 1333.3 Mhz clock speed. I tried several utilities and all of them show only 666 MHz. Any clues?
