Hello @python12321

Welcome to the HP Support forum.

This is happening because the computer cannot successfully and fully load Windows. It is attempting automatic repair.

This may be hardware problem or software problem.

Please, clarify the following:

- Did you perform some change recently ,something new these days, last hours before the issue started ?

- Could you please post the product number as mentioned here >> http://support.hp.com/us-en/document/c00033108

- Did you PC come with Windows 10 preinstalled by HP or it had previous Windows before (7/8) and you upgraded it to Windows 10 later ?

Please, perform some basic hardware checks

1. Please, shutdown the computer using the power button

2. Power it on.

2.1 As soon as you press the power-on button, immediately begin hitting the Esc button (like tap-tap-tap).

This should open a HP Startup Menu which may look similar to this one

3. Choose F2 to open System Diagnostics. Follow the on-screen instructions to perform System Test >> Quick test.

This will check major hardware componets for issue (do it just in case) . Here is more info >> http://support.hp.com/us-en/document/c03467259#AbT1

If there are no system checks/no quick tests, perform HDD and RAM check.

Let me know the test results.
