After power supply problem, pc crashed several times, it seems to have got itself in a knot now. When powering up it goes into hp screen, preparing automatic repair, then goes into diagnosing your pc. Then checking disk for errors. Then fixing errors. On completion. Says restart. On restart. Starts the whole process again. Will not get past this and into windows. Can some body help please.

@Grajack Welcome to HP Community!

I understand that you are getting preparing automatic repair message on the screen.

This is 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. Perform some basic hardware checks to rule out a 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 >> https://www.youtube.com/watch?v=6JXUp43ahHA

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

2. 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 a 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:

Hi, many thanks for replying to my issue, I have done the tests as per your suggestion, all passed, I tried the restore from 3 separate restore points, all failed, I thought the final one was OK as I got the message restore finished, but shortly got another message saying it had failed. Any further help you can offer would be appreciated. For your information, the original crah was caused by a faulty power supply which I have replaced.
