The behavior that you are describing could be caused by many things, however the easiest way to determine if the processor is the cause is by testing the processor on a different known working and compatible motherboard.
If you do not have a spare motherboard to test with, you can test it on a friend’s motherboard or by taking the processor to a local computer store to be tested.
