"Warning!! CPU have been changed" - Whaa Whaa Whaa?

You may have the CPU in the correct orientation, but not completely seated in the socket. I'm also surprised you have a primary slave with no master...that's not right. In any case, try reinstalling the CPU. Don't push down hard, but make sure it is all the way down in the socket. Did you use an anti-static wrist band when you handled it? If not, you may be in trouble...
