I was watching a youtube video while tabbed out from the game. Suddenly the PC hangs and immediately bluescreens. I was startled and didn't see what BSOD it was.
I don't know how to read the crash dumps to find out what caused the BSOD or what type of BSOD it was.

I am updating some drivers as I type this just in case, but would like someone to look at the dumps and tell me what crashed me and how much of a threat it is.

Since my last post, which was also a BSOD (Caused by killer network) I haven't had any BSOD so updating that worked like a charm!
So this must be a new issue.

It looks like the Killer network drivers are acting up again. Though, seeing as this looks to be just one crash, see how things go for now.

Do you use the Big Foot software with your Killer driver? I have the E2200 driver....driver only. I don't use that software. I classify it as bloatware, the same with Nvidia GeForce Ecperience software.

I had a quick look at this earlier, it's a 0xc2 bugheck and bflwfx64.sys was involved. It's a driver/filter for the Killer software, part of the gui/tuning package rather than a main driver - I think.

I'd try to install drivers only but I've no clue if that's possible (similar viewpoint to the response immediately above this). Ah I see, Big Foot = bflwfx64.sys

Yah....that software is a big PITA. If you use it as suggested in setting parameters on devices bandwith access, it tends to create havoc for over all system performance and because of that I don't use it anymore. I learned the hard way some years back.

Killer does offer an uninstall tool from their website.

Thank you, I have no idea what the Killer Network thing even does. What will happen or stop working if I uninstall it? What should I do?
I do not know what BigFoot software is, never seen that on my PC, nor do I know what the E2200 driver is.
Someone else installed all this when I got the PC.
I only use GeForce Experience because of its driver updating.

The Killer and BigFoot drivers are for your network connection, without you would not be able to ask for help here.

I have a Killer network card in one of my systems at work and run only the drivers. I uninstalled the GUI software a year ago and everything runs fine.

It's my understanding also that the Bigfoot/Killer front end/gui is quite separate from the basic NIC drivers, as in many 'tweaking'/3rd-party applications, they add fluff and instability (@axe0: think of ASUS' 'added value'/bloatware (also used by Gigabyte) drivers/filters and the number of times they've been flagged up as being involved in BSODs).

Similarly the GeForce 'Experience', useful for installing the latest GeForce drivers - useless for getting the most stable or fastest drivers, good for (more) telemetry and great for adding bloat - my W7 w/1060 GTX 6GB loads only one nVidia driver, no Processes, no Services.

@xrobwx71 can you find a good howto for going drivers only with that NIC/uninstalling the gui/bloatware?

I used Revo Uninstaller Free to uninstall the GUI software for the Killer suite. (As I do with all my uninstalls) I can't remember what it was called The Killer Control Center, but it was separate from the drivers. I also uninstalled the drivers at the same time. I downloaded the driver only package from Killer and installed the latest.

Or you could go the route of @bassfisher6522 suggestion here BSOD during a game

As far as Nvidia Experience, on the next driver install, just uncheck everything but the drivers and physX and click the box for a clean install.

If the additional software really is a bother, then only download the drivers from the support page, remove the software, and reinstall the drivers manually via device manager.

To install manually, in device manager right click and select update drivers, click browse my computer for driver software and choose the folder that contains the Killer network drivers (extracted from the downloaded zip).

No direct experience of Killer/BigFoot so I can't add more. A full bloatware/telemetry-free install of nVidia graphics driver is more complex but just installing the minimum allowed by the installer would go a long way to aiding stability.

If you have Steam autostarting, I'd stop it from autostarting and make sure Steam is updated. In some cases, the Steam game overlay can cause issues so stop it for now until you get the Killer issue sorted.
I am only a student at the BSOD Academy at Sysnative and I defer to my instructors above. :)

Thanks for the many replies. The drivers only is an .exe not a zip and also says windows 10 , but I am windows 7.
Is Bigfoot the same as killer or something else?

I should have uninstalled and installed the driver only. Installing that seemed really easy and only took a split second. Hopefully I did it correctly. Since I can connect to the internet again, I assume I did it right.
Now I hope there won't be any more BSOD from that. Or at all. Should this be closed or remain open if new BSOD happens?

Device Manager network adapters shows "Killer E2200 Gigabit Ethernet Controller" , that should be the driver.
There's also "Teredo Tunneling Pseudo-Interface" no idea what that is. It's got a yellow warning icon underneath it's icon.
That anything important?

Keep it open until a week or ten days have passed without a BSOD.
