Hi darthtony,

Welcome to the 10forums :)

Your Logitech Webcam 300 is causing the crashes, please make sure to update the drivers.
Driver Reference Table - lvuvc64.sys

EDIT: it seems the AVG activity monitor driver is being flagged too in 2/3 dumps, worth mentioning thus.
I would suggest that you temporary remove AVG and use Windows Defender as alternative.
In the link below, go to part C and download the uninstaller to ensure AVG is proper removed.

In case you've missed my edit in my post I'm posting it again :)

Thank you very much for your assistance, I updated the webcam drivers and unistalled AVG, i will see how it goes from here. For future reference, how do you check which driver/process is causing the crash?

Learn debugging memory dumps to find the driver causing it, or to find the problem :)
WinDBG - Install Configure - Windows 10 Forums
WinDBG - The Basics for Debugging Crash Dumps in Windows 10 - Windows 10 Forums

Note that it isn't quite as easy as it sometimes may look like, there are several different kinds of crashes of which some do require understanding of a bit more than the basics but don't let that discourage you, do research on the things you don't understand/know & ask and keep trying is the best advice one could give.
