I just recently upgraded to windows 8 since I got a free copy from MSDN because I take Cisco courses in college and my computer was badly in need of some spring cleaning and good ol'fashion formatting anyways. Recently I've been getting these BSOD Kernel_Security_Check_Failure crashes which with a simple Google search I was able to ascertain is generally associated with drivers. I've updated all my drivers and still encounter this problem, it mostly happens when I start playing a game, but as I play more and more of the game the crashes seem to stop and then when I install and play a new game they start happening again. My NVIDIA GeForce GTX 560 is updated with the latest drivers so I'm a bit at a loss. I've included my dump files in a zip that is uploaded to a public skydrive folder for review.

ll of the attached DMP files are of the KERNEL_SECURITY_CHECK_FAILURE (139) bugcheck.

This bug check indicates that the kernel has detected the corruption of a critical data structure.

BugCheck 139, {3, fffff88001685fc0, fffff88001685f18, 0}

As we can see, the 1st parameter of the bugcheck is 3 which indicates that LIST_ENTRY was corrupted. This type of bugcheck can be difficult to track down and indicates that an inconsistency has been introduced into a doubly-linked list (detected when an individual list entry element is added to or removed from the list). Unfortunately, the inconsistency is not necessarily detected at the time when the corruption occurred, so some detective work may be necessary to identify the root cause.
