@doomgiver, Thanks for your reply.
I have 3 External HDDs connected through 3 different USB ports. Transcend 250 GB, Seagate Goflex 500 GB, both without power-supply and Seagate 1 TB with external power-supply. I pulled out 2 External HDDs and after which I had not experienced the problem so far. I have turned the system on and off about 5 times so far. Keep you updated.
Could this be the reason for rebooting?

If you go to advance boot up menu [by pressing F8 key when windows is booting up]....you will get an option for disabling automatic restart.It may give us an error code to diagnose the problem:
Advanced startup options (including safe mode)

After removing the external hdds ,( I removed 2 of the 3 ext hdds connected via the USB) , the system starts smoothly.
Thanks for the replies.
