I would revisit using Display Driver Uninstaller, and make sure to follow the steps provided by the creator of that app, because you’re still showing as using an old driver. The current version of the driver was released on January 15, 2019. Even if this isn’t the issue, being on the latest version will help you get the most out of your hardware.
Make sure that you enable High Performance Mode in the nVidia Control Panel, and also for Windows Power Settings. You will probably need to remain plugged in to use High Performance, but this will significantly impact your game.
Since we’re seeing a lot of these errors, both with the Windows shell (the parts of windows you see and use to interact) and with your CPU, makes me think you should check for overheating. Make sure the fans are clear of dust and the laptop can “breathe” while you use it. Also, it wouldn’t hurt to use the Windows built-in tools to check for errors on your hard drive (check disk).
If you try the above stuff and still have issues, we can look at more in-depth info with HWMonitor, but hopefully these things will take care of it.
