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?
• Have you tried any troubleshooting steps?
• Did you make any changes to the settings of your PC prior to the issue?

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

Use the following steps to perform a hard reset on a computer:

1. Turn off the computer completely; disconnect the power cord from the back of the computer.

2. With the power off and the power cord disconnected, press the power button on the computer for 5 seconds. The power light indicator on or near the power button might turn on briefly but then go out.

3. Reconnect the power cord and turn on the power.

   • If the computer starts, you are done.

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.
