Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

• Did this happen after a recent window or software update?
• Have you made any hardware/software changes?
• Did you make any changes to the settings of your PC prior to the issue?
• When was the last time it worked fine?

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

Hard Reset: Follow steps from the link: https://hp.care/2GnkMa8. (do not skip any troubleshooting steps even if you feel steps are repeating)

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.

Thank you for posting back. 

let’s try these steps to resolve the problem:

I recommend you attempt to access the BIOS screen by tapping on F10 while the computer is restarting, 

If the issue persists in the BIOS screen which is outside windows, it would confirm a hardware failure.

Hope this helps! Keep me posted for further assistance.
