computer freezes during boot up process

[Idgie25]

Computer was doing updates 2 days ago and froze black screen. Now will not boot up. Starts process and then freezes. It did boot up once yesterday and was fine for a few hours, then got a message saying computer had a problem.

Error message:

SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (atikmdag.sys)

Now its back to not booting up again, freezes with the HP logo on screen.

Hi there @ldgie25,

May the Forums be with you!  I understand that after some updates your computer is not starting properly, and freezes on the HP logo.   I am happy to help with this.

Since it did start the one time, but then had a Blue Screen error, I would suggest using HP PCs - Using Microsoft System Restore (Windows 10, 😎.   Follow the instructions in the section "Restore your computer when Windows cannot start normally".  See if it will start normally after the restore. If yes then you will probably want to prevent the offending update from installing again.

Please see the following for how to do that: 

How to temporarily prevent a driver update from reinstalling in Windows 10  - support.microsoft.com

How to Uninstall and Block Updates and Drivers on Windows 10 - howtogeek.com

Please let me know whether that works for you, and if it does resolve your issue, please mark this post as a solution. Kudos would also be appreciated.
