Hello Sampath,
Have you preformed any BIOS updated lately? Which is the current BIOS version of your motherboard? Any chance made on BIOS on these days?
- You may want to test the system out of the chassis, minimal configuration. (Motherboard, processor, power supply)
- Test the system without memory since we are looking for beep codes
- Remove the CMOS battery and leave the system without it for about an hour. Then put it back on and restart the system. http://www.intel.com/support/motherboards/desktop/sb/CS-028780.htm?wapkw=clear+cmos+battery#datetime
