if nothing changes, the system disk probably needs to be replaced
if you followed correctly what is mentioned here
at some point you must have checked the status of the hard drive, if present, and then attempted a factory recovery..
as mentioned in my answer, if nothing works with what is stated in the links, then you definitely need to replace your system disk
1:Open the Component Tests menu when Windows won't start
When Windows won't start, use the following instructions to open the Component Tests menu.
Hold the power button for at least five seconds to turn off the computer.
Turn on the computer and immediately press esc repeatedly, about once every second. When the menu is displayed, press the f2 key.
On the main menu, click Component Tests.
Perform hard drive tests in HP PC Hardware Diagnostics
you speak at a moment of memory?
is it the system hard drive test, or the ram memory test that failed here?
test ok

The computer stops responding and displays this message: Boot Device Not Found 3F0.
Procedure 4: Perform F11 Recovery, or restore the system using HP recovery media.
Reinstall Windows 10 on the hard drive
Reinstall Windows through the Windows Recovery Environment (f11) or using the HP Cloud Recovery Tool.
