Hi Oneifone,

I am Dave, I will help you with this, are you able to boot into Windows normally?

If you can boot into Windows

Please check to see if your PC is producing any minidump files, I will check those to see if they provide any insight into a potential cause of the system crashes.

Open Windows File Explorer.

Navigate to C:\Windows\Minidump

Copy any minidump files onto your Desktop, then zip those up.

Upload the zip file to the Cloud (OneDrive, DropBox... etc.), then choose to share those and get a share link.

Then post the link here to the zip file, so we can take a look for you.

If you cannot boot into Windows:

Start your PC, just as Windows attempts to load (spinning dots), press and hold Power Button for 5 - 10 seconds to perform a Hard Shut Down

Do this twice

On the third start Windows will boot into the Recovery Environment and from there you can access System Repair, Safe Mode, Command Prompt... etc.

Please try each option one at a time, then see of Windows will boot.

If there is an option to uninstall that update, that will be the best option

Otherwise, try to boot into Sage Mode and see if you can get the minidump files:

Go to Troubleshoot - Advanced Option - Startup Settings and click Restart

Upon restart, press 4 to enter Safe Mode
