Help with BSOD "Unexpected Kernel Trap Mode" error

Hello people that are smarter than me...

Recently upgraded to 8.1 and all things have gone downhill since. Currently getting BSOD and I could use some help.

System info:


Thanks all.

All of the attached DMP files are of the UNEXPECTED_KERNEL_MODE_TRAP (7f) bug check.

This bug check indicates that the Intel CPU generated a trap and the kernel failed to catch this trap.

BugCheck 7F, {8, ffffd000201d6130, ffffd00026a9dff0, ffffe00003694dfe}

The 1st parameter of the bug check is 0x00000008, or Double Fault, indicates that an exception occurs during a call to the handler for a prior exception. Typically, the two exceptions are handled serially. However, there are several exceptions that cannot be handled serially, and in this situation the processor signals a double fault. There are two common causes of a double fault:
  • A kernel stack overflow. This overflow occurs when a guard page is hit, and the kernel tries to push a trap frame. Because there is no stack left, a stack overflow results, causing the double fault.
  • A hardware problem.

^^ Asus ATK0110 ACPI Utility (a known BSOD maker in Win7 and Win8). Also a part of many Asus utilities. The driver is dated from 2005 which is FAR too old to function with Windows 8.

Go here -

and select Windows 8 64 bit (Windows 8.1 driver not available, so 8 will have to do). Select Utilities > download and install ATK0110 ACPI Driver for Windows 8 32bit and 64bit.

2. The most common problem after upgrades is antivirus and firewall software doesn't transition properly and causes memory corruption due to compatibility issues, etc. With this said, please remove and replace ESET for temporary troubleshooting purposes:
