Sumit_123, my recommendation for this kind of issue will be to do a complete troubleshooting on the system before suggesting you to replace the board or the processor.
Please follow these steps:
- Take the motherboard out of the chassis and test it with minimum configuration (Motherboard, processor, power supply)
- Since the system does not have memory you should get a 3 beeps sound coming out from the board.
- Remove the CMOS battery and leave the system without it for about an hour. Then put it back on and restart the system.Desktop Boards — Troubleshooting BIOS Issues
- add 1 memory stick into de the motherboard and turn on the system.
- Start adding one component at the time until you find the conflicting one.
- If the issue persisted it will be necessary to test the board using another compatible processor.
- You can also try another power supply just in case.
