I tried installing a web cam onto my PC today, however when I try to run it a blue screen and the 'Kernal_security_check_failure' error keeps appearing. I'm guessing it's an issue with the web cam, but I'm not that great with computers past the basics so any help would be apprecaited.

Thanks very much!

All of the attached DMP files are of the KERNEL_SECURITY_CHECK_FAILURE (139) bug check.

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

BugCheck 139, {3, fffff8001814ffe0, fffff8001814ff38, 0}

The 1st parameter of the bugcheck is 3 which indicates that a LIST_ENTRY was corrupted. Code 3, LIST_ENTRY corruption. This type of bug check 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).

ETdrv.sys is a Gigabyte Tools Easy Tune 6 driver, very problematic software. Please uninstall all Gigabyte software ASAP!
