Help reading dmp files for bsod


Sep 24, 2017
So for the past few weeks, I've infrequently been getting a bsod with the error "dpc_watchdog_violation." It sometimes happens every time I boot my computer and sometimes will run fine for days before crashing. I've tried everything I could find, from updating drivers, checking memory, even a full system reset, but nothing is working. I thought to use the dmp files to find the exact problem, but I kept having problems with that too. If anyone is able to look at the dmp file and tell me what is causing this error, I'd be grateful. I'm including a link to a zipped folder with the dmp file in it. Any help would be greatly appreciated.
you might have a usb device that is causing problems with your usb network driver.
you might put your usb device on a different port (usb 2 port if it is on a usb 3.0 port)

if you change the memory dump type to kernel, then the proper info can be read from the new memory dump file. C:\windows\memory.dmp (otherwise it is just a guess as to the real problem)

(stack was corrupted in the usb network driver)
netr28ux.sys Thu May 28 07:28:52 2015
Ralink RT2870 series USB802.11n Wireless Adapter Driver (you may have a different manufacturer)

NOTE: BIOS Version P7.20

update the audio driver:

and go into device manager and disable the gpu high def audio driver if you don't have speakers in your monitor that get the signal from the video cable.

this is a guess because of the GPU and audio calls just before the network driver data was corrupted.

- you might also go into bios and reset it to defaults and reconfigure so the bios rescans the hardware and updates the database of settings it sends to windows.

@johnbl, you're sure it's a corrupted stack? Not an alternative of missing symbols, or just a lack of data as it's a minidump?

Netr28ux.sys is a network driver. I do know Intel doesn't use this driver and the Intel lan device is the only network device for this motherboard.
The chipset drivers being involved make sense with a USB network driver.

@aroband, check if Ralink (or the manufacturer of Ralink is not the manufacturer) has driver updates. If there are no driver updates and reinstalling doesn't help, try the USB adapter in either a different USB port or a different system.
if the usb device is on a usb 3 port, move it to a usb 2.x port
(just as a guess that is problem with the usb 3.0 port )

list this as a Ralink RT2870 usb wireless driver.
the kernel dump might be more useful to see what is going on with the other cores but here is what the minidump had:

I dumped the raw stack, saw the audio call, video call and the usb3 hub and along with the netr28ux.sys
calls. Since the netr28ux.sys was from 2015 I would guess that it has already been updated.
that is why I suggested changing the port from usb 3. to usb 2, update the motherboard audio, and disable the gpu high def audio. Most are just a guess as to something to try.

I could not see what is going on with the other cores, Need a kernel dump to check for common plug and play issues, and old devices installed on the USB ports. (to check for old mouse with old broken firmware type problems) Or plug and play attempting a install on one core while the device is being used on another core type problem.

you might also go into your bios and see if you can prevent your usb ports from going to sleep. (or go into device manager, right mouse click on the usb ports and find the power management tab and see if you can block the sleep functions. (just a guess at something that could be triggering the problem with the network driver.
you also have a device that failed after it was started:
here is the list of devices that did not fail:
Desc: A6210
USB\VID_0846&PID_9053&REV_0100 NETGEAR, Inc.

Desc: Gaming Keyboard G910

here is the one that failed:

looks like the device stopped responding, the usb tried to reset the port and the device just never recovered.

stack shows calls to the
(date time stamp messed up)
just before it made calls to
\SystemRoot\System32\drivers\netr28ux.sys Thu May 28 07:28:52 2015
then a bugcheck.

your motherboard uses a usb 3.1 chip
this chip requires updates for its firmware or from the bios.

since it looks like you are using the windows 10 generic usb extension files, you might require a update to your bios (which is current) or a special firmware update to the chip itself. I can not tell. or it can just be a bug in the USB wireless driver.

since your wireless driver is older (usb 3.0) days it could also be a bug in that driver. just very hard to tell. media tek now owns the company that used to make the chip and drivers for you usb wireless device. getting updates might be hard. I did not see any drivers on their website.
maybe the actual vendor of the usb device will have a update on their website.

you might also be able to go into bios and find a option to turn off the usb extensions so your usb chip acts as a standard usb device. or put your usb device on a usb 2.x hub
