Blue screen error. Stop code PNP DETECTED FATAL ERROR. Any help with this?

[Andries4]

HP Pavilion Notebook 17-g078ca.

Blue screen error.

Stop code: PNP DETECTED FATAL ERROR.

I was using the laptop as usual, looking up a few things in the internet, left it in sleep mode and closed it while I got a drink. When I came back, opened the laptop again, and the blue screen message was there. Could not access anything after this and could not either reset or restore as I have forgotten the password used with the email in the laptop.

Many thanks for any help.

Let's do these in reverse order ...

As to the password, If you use a Microsoft account for your Win10 access (you would know that because the login screen shows either a pin code or an email address), then you can go to the Microsoft account reset website: https://account.live.com/password/reset -or - go to the Sign in Microsoft Account website: https://login.live.com/

Then follow these instructions:
1) Click/tap on the Can't access your account link
2) Select why you can't sign into your account and click/tap on Next
3) Enter the email address of your Microsoft account, type in the characters displayed onscreen, and click/tap Next
4) Select how you would like to get your security code to verify your identity, click/tap Next
5) Enter your security code sent using the method selected in 4) above, click/tap Next
6) If you have enabled tw0-step verification, repeat steps 4) and 5) above using a different method to send you a different security code
7) Type in a new password, click/tap Next
😎 Your Microsoft account has been recovered -- click/tap on Next -- and you're done

However, if you use a LOCAL account, then you can not use the websites or instructions listed above, and we can not assist you in this.

=============================

As to the blue screen, this code usually means that some device connected to the PC is trying to use a driver that no longer works with Windows 10.  This can happen easily if you upgrade from one version (say 20.04/20H1) to a newer version (say 20H2) and one or more of the existing drivers no longer works properly.

Is this what you did?
