So I will run the 8hr mem test tonight and post the results tomorrow. I tried to go and create another log for you to show where it's crashing using the following steps:
Open Command Prompt (cmd.exe)
Run: C:\ProgramData\NzbDrone\bin\NzbDrone.Console.exe > C:\ProgramData\NzbDrone\output.txt 2>&1
I've attached the extremely short log it gives: https://drive.google.com/open?id=0B6SdVz5hFc0VTUhJY1p4dXZQeFU - I then end up on a page addressed as localhost:7878 but the contents of the page are blank except for the following text:
"message" : "NotFound"
So through this means, it will not even launch Sonarr anymore. Shortly after that I get a pop-up stating that NzbDrone.Host has stopped working with the only option being to "Close program".
Lastly, I've just updated the video drivers and am at the most current one available - issue is still present.
