Hi darthtony,

Welcome to the 10blog

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

Code:

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.

Hi darthtony,

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?

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.
