1. Check the MB BIOS version, if it does not have the newer version, update it. Keep in mind, the BIOS update may or may not brick your MB, if you do not do it right.
2. Check the cpu to see there is any bent pin(s) or not.

There is no bends but 3 pins are missing, i am not able to proceed to the point where i could update bios
