BSOD: The bugcheck was: 0x000000df

Hello!

I manage a small team of users running Windows 7 on a network and one of them is getting the BSOD with error "The bugcheck was: 0x000000df".

I tried various things to fix it and using Norton to clean everything up, and uninstalled various useless programmes. The problem seems to have subsided for her.

Then... I changed my own Norton installation from Norton Internet Security to Norton Security with Backup.. and five minutes after I do this I get the same BSOD with the same bugcheck!!

From what I can tell the 0xdf error seems to be a "IMPERSONATING WORKER THREAD" error but I cannot find out how fix this other than usual update drivers etc. Can I find out exactly which programme is causing this? Could it really be Norton or is that just a coincidence? I really don't want to have to do a clean Windows install. 

The full error is The bugcheck was: 0x000000df (0xfffff800033b56c0, 0xfffffa800778cf40, 0xfffffa800778cf40, 0x0000000000000000). 

Any help would be greatly appreciated. I am downloading the Windows 7 SDK to be able to open the memory.dmp file now.

Here is a link to the dmp file: https://www.dropbox.com/s/f4qt2xojeadmxcu/MEMORY.zip?dl=0

Thanks!

Daniel

    Interesting - that was one of the theories I had - all the affected machines here are Dell boxes.

    Please let me know if the video driver udpate fixes - I will update as well.

    It could easily be both problems.  Your current video driver is from 2014.  There are much newer

    For future reference please upload the DMP located @ C:\windows\minidump.  They are 10x smaller so faster for you to upload and us to download.  I am currently on a 4g metered connection and downloading a 1gig file chews through data in a heart beat.

    I started the driver verifier and it crashed very soon after, but the BSOD now gave a bugcheck of 7E! I am uploading the dmp file now but I looked at it myself and it mentions the igdkmd64.sys driver which seems to be an Intel display driver. 

    The dmp is here https://www.dropbox.com/s/sa41ast84144val/MEMORY.zip?dl=0 although still uploading

    It then crashed again but i waited for the BSOD to appear but it never did so I physically restarted the PC with the start button.

    Would this be the same driver causing the DF problem or is this a new problem?? I am updating Display drivers now.

    PS as it crashed again so quickly I have since disabled the verifier.

    Thanks!
