Thank you for posting on the HP Support Community.

  • Did this happen after a recent window or software update?
  • Have you made any hardware/software changes?

While you respond to that, let's try these steps: 

Hard Reset: Follow steps from the link: https://hp.care/2GnkMa8. (If the computer boots up normally then continue the next step)

BIOS default: 

  1. Turn off the computer and wait five seconds.
  2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
  3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
  4. Press F10 to Save and Exit.
  5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
  6. Follow the prompts to restart your computer.

Hope this helps! Keep me posted for further assistance.

Hi @dante2

 

Try these steps -

 

1) Shutdown the computer. 
2) Hold down the Windows and B button together while the computer is still turned off. 
3) Turn on the computer and continue to hold the Windows and B button until a BIOS Recovery screen appears. 
4) Follow on-screen instructions and click on OK
 

If the issue still persists, perform the hardware diagnostics -

 

1) Hold the power button for at least five seconds to turn off the computer.
2) Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.
3) On the HP PC Hardware Diagnostics (UEFI) main menu, click System Tests. Click Extensive Test.

 

Keep me posted.
