Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help,

Firstly, perform Windows Update and HP Support Assistant: (do not skip any troubleshooting steps if you feel steps are repeating) 

To check for updates now, select the Start button, and then go to Settings  > Update & security  > Windows Update, and select Check for updates.

Install updates from HP Support Assistant: Go to Download HP Support Assistant to install the tool.

  1. To open HP Support Assistant, double-click the HP Support Assistant icon.
  2. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.
  3. Click Check for updates and messages to scan for new updates.
  4. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.
  5. Click the update name for a description, version number, and file size.
  6. Select the box next to any updates you want to install, and then click Download and install.

If the issue persists, Turn off the computer and be sure that the AC adapter is connected to power.

Press and hold the Windows + B keys, and then simultaneously press the power button.

After 2 to 3 seconds, continue to press and hold the Windows + B keys, but release the power button. You might hear a series of beeps.

If this recovery method fails, use another working computer to create a BIOS recovery flash drive to install the latest BIOS file.

 

Hope this helps! Keep me posted for further assistance.
