Solved Regular Kernel Security Check BSOD on Windows 8.1 Pro

Hello,

We have a Dell PC running Windows 8.1 Pro and in the last day or so, we have started to get regular (within 30 mins of restart) "Kernel Security Check failure" BSOD crashes. We have not installed or changed anything recently so this is a mystery.

I have followed the guidelines in the Blue Screen of Death (BSOD) Posting Instructions and generated a zip file which I have attached below.

Any help gratefully received!

I found a link that showed how to debug the dmp files and it seems that the issue maybe be due to this bug in Windows 8.1/2012 R2. I applied the Hotfix KB3055343 and since then, no BSOD's .. finger's crossed this is the solution!
