Hello @RoniO 

Welcome to the HP Support Community. Thank you for posting.

When did the CAPS lock blinking start ?  Was it there from the beginning or after trying the Win+B option ? Please, clarify

• If it blinks - this will be BIOS or hardware problem for sure.

• If we exclude the blinking/flashing of CAPS lock - this may be happening because Windows cannot start/boot .It may be caused due to simple Windows hung, hardware problem (e.g. your HDD) or it may be caused by faulty Windows Update, some other faulty update/driver, corrupted bootloader / Boot Configuration Data in Windows etc....

1. Try hard restart/hard reset.

Press the power on-button on your PC and hold it for about 5-10 seconds until your computer powers off completely.

Remove and unplug any external periferals and accessories.

Press once the power-on button to turn on the PC and wait if it will start now. Wait...

If it still fails to load properly, go ahead with the next steps

2. Perform some basic hardware checks to rule out hardware problem

- Please, shutdown the computer using the power button (pressed and hold for a few seconds until PC powers off)

- Power the computer back on.

As soon as you press the power-on button, immediately begin hitting the Esc button (like tap-tap-tap) before any logo appears. This should open a HP Startup Menu

- 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 (hard disk drive) and RAM check (memory check).

Let me know the test results. If the tests pass without issues, continue. If not, please, let me know

3. Repeat steps 1-2 above but when HP Startup menu opens, please choose F11 for System Recovery options.

The computer should boot from it's recovery partition to open you various recovery options. Note, that F11 option will only work if the recovery partition is there (not deleted) and intact. From there, you have prenty of options to choose from. Every HP computer comes with recovery partition present to assist in tough moments.

Please, perform "System Restore" first in an attempt to fix the issue. Please, restore back to previous days (restore point) where the issue was not present. Here is more info:
