Thank you for posting on HP Forums,

As I understand, your notebook boots to a blank screen 

No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution:

What is the product number of your device? Use this link to find it: http://support.hp.com/us-en/document/c03754824 

(Ensure you do not share any of your personal information such as serial, phone number, email ID, etc...).

Have you attempted any steps on your own before posting on the HP Forums?

When was the last time it worked without these issues?

Were there any hardware/software changes made? 

Let's try troubleshooting steps from the link: Click here

Step 3: Recovering the notebook BIOS using a key press combination

Let me know how this goes,

Cheers!
