Hi, I am Dave, I will help you with this.

Completely remove the current Nvidia device driver using the widely available free DDU utility, then restart your PC and go to the Nvidia website to download and install a couple of slightly older version of the Nvidia device driver to try to find a version that is stable on your system.
A slightly older version of that driver is more stable than the latest version.

With regards to activation and that SLUI error, was Windows activated on that laptop when you purchased it and it is now not activated?
Download the free ShowKeyPlus app from the Store, please provide a screenshot of that app window and please hide the product key that may appear in the screenshot.
