Pc won’t start properly. Error code:d0000452

Hi Alex,

Error d0000452 can be caused by damaged registry files, malware, hardware problems, software conflicts, and corrupted system files.

For us to better assist you, we'd like to know if you've installed any software or made any hardware changes on your computer prior to the issue?

In the meantime, since you're unable to boot your computer in normal mode, try booting your computer in safe mode. Click on Advanced Options (which is being provided when booting up your PC) > click Startup Settings > choose Restart > After restart, you'll see a list of options, select or press 4 or F4 to start your PC in Safe Mode.

If you were able to boot into safe mode, there's a possibility that the issue is coming from a third-party application so perform a clean boot to eliminate any software conflicts.

Note: Refer to How to reset the computer to start normally after clean boot troubleshooting section of the article to know more information on how to start your computer in normal mode after the clean boot process.

To go out from safe mode, right-click on Start > click Run > type msconfig > press Enter> under Boot tab, uncheck Safe boo****t > Restart.

Let us know if you need further assistance.

Thank you for the update.

when i pressed startup settings and then restart it came up with a screen saying “there was a problem, restart your pc to try again”, this was what happened before. There was a restart button which i pressed but brings me back to the screen that says “boot menu” and “app menu” with two options. None of the options in the boot menu options do anything and the app menu options comes up with some wierd setting options that have enabled and disabled next to them.

Hello Alex,

I am currently facing the same computer issue as you. What was the diagnostic issue with your laptop? Is it an issue that would require me to take my laptop to get repaired by a professional?

Thanks a lot for your help, in the end i just handed my laptop in to the store to fix it. Thanks anyway.
