There is the possibility that some CPU socket pins could be bent or perhaps broken off altogether, or the CPU latch is not giving the required tension for a solid connection.
Bent pins can be straightened out with a little luck and strong manual skill as well as the appropriate tools are required. As for missing CPU pins one can only hope these are the grounding pins - the CPU socket has many of these and usually even if a few are missing the CPU will still work fine.
