Thank you for posting on the HP Support Community.


Don't worry as I'll be glad to help, this sounds like hardware related issue with the computer as you've changed hardware parts and the issue persists I would suggest you need to ship the computer for a complete diagnosis in order to isolate the issue. 


I would request you to contact our Support and our Support Engineers should be able to sort this out based on your warranty. HP Support can be reached by clicking on the following link:
