Thank you for posting your query on HP Community,
Let's start off by performing a Hard reset on the notebook:
Before power resetting your computer, do the following:
Disconnect or remove all peripheral devices. Start up the laptop and test the computer by itself, and then reconnect one peripheral device at a time.
Turn over the computer and look for a battery compartment door.
If there is a battery compartment, use the steps in Reset a laptop with a removable battery.
If there is no battery compartment, use the steps in Reset a laptop with a sealed or non-removable battery.
For starters please try to roll back the bios from this link: http://support.hp.com/us-en/document/c02693833
Please try both the steps mentioned in the link.
If this does not do the trick, please try all the steps from this link: HP Notebook PCs - Computer Does Not Start (Windows 10)
Alternatively, you can also go through this support document: If the LEDs blink, or the computer beeps, but it does not start, go to HP Notebook PCs - Troubleshooting LED Blink Codes or Beep Codes During Startup or Boot.
Please try these steps here and let me know how it goes for further assistance!
