@SimrSawyney28 Welcome to HP Community!

I understand that you are getting a black screen with the HP logo.

I have a few steps that should help,  

Some HP Notebook PCs come with two sticks of memory and have two memory slots. If you experience a black screen or blue screen with HP logo, the problem could be with one of the sticks of memory or with one of the memory slots.   

 
To determine what is causing the failure, try to isolate the problem by:  

• Performing a memory self-test   

• Checking for loose memory modules   

• Testing the memory modules   

• Testing the memory slots
