I've been getting this BSOD a couple times of day and haven't been able to fix it. I believe its a problem with the Killer Network drivers but I updated to latest drivers provided from my motherboards website: MSI. They happen randomly and it doesn't occur when I'm doing something specific. I uploaded my minidump files.

Hi Ski3high & Welcome to the forums ^_^,

I have analysed your dump files and below has been provided an analysis of the same for informative purposes :-

So the Killer Network Driver caused a Divide Error which caused the BugCheck.
There is a workaround for this specific problem. Try this below -

I cant be too certain but this seemed to have helped. I haven't received a BSOD all day.

Unfortunately, I've gotten about 3 BSODs. I'm almost certain it is a problem with the killer e2200 drivers. I get my drivers straight from MSI website. Ive tried getting them from qualcomm instead since they seem to regularly update their drivers but it wouldn't recognize my Killer nic. I'm completely out of ideas at this point.

Could you please upload a freshly generated SF Diagnostic ZIP File?

Did you follow the workaround? What was it's result?


EDIT :- Can you try this thread and see if it helps you or not - https://forum-en.msi.com/index.php?topic=178064.0

Okay its been about 2 days and I'm almost certain that, the new method in that forum has performed the trick. I also had issues with the stability with some of my games and people reported that the e2200 killer drivers were in conflict with some games. This problem has since been fixed.

Thanks for your kind words and the virtual rep from your mind ^_^. I have also submitted this fix in the DRT for the Killer Network and the same driver with which the OP had issues with :)
