@TheChiefUSN Welcome to HP Community!

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 the 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

let me know how that pans out,

And the answer to the above question will help me, help you!

Keep me posted, and if any of the above questionnaires helped resolve the issue, 

Mark this post as an "Accepted Solution".

Good luck.
