Laptop not booting

Hello,
I am Samuel Adjetey. Please can you help me find solution to a problem I am facing with my laptop. I changed the processor of the same kind when the computer stopped displaying. Now it won't just boot.
Please what do I do?
The laptop type is a Compaq nx 9010 with an AMD processor.

Thank you in Advance for your kind gesture. God Bless you.

Have a nice time

Bye

Sammy Adjetey
