Hi,
We have three dumps, two bug checks:
SYSTEM_SERVICE_EXCEPTION (3b)
This indicates that an exception happened while executing a routine that transitions from non-privileged code to privileged code.
This error has been linked to excessive paged pool usage and may occur due to user-mode graphics drivers crossing over and passing bad data to the kernel code.
Code:
STACK_TEXT:
fffff880`1b3e9830 00000000`00000000 : 00000000`00000000 00000000`00000000 00000000`00000000 00000000`00000000 : dxgmms1!VIDMM_GLOBAL::BeginCPUAccess+0x16d
^^ dxgmss1.sys is the DirectX MMS, a component of DirectX. VIDMM_GLOBAL::BeginCPUAccess - ??? Very hard to tell what's going on as I cannot find proper documentation, and it's a very uninformative stack. If maybe after the 'BeginCPUAccess' call we had an 'xWaitOnDMAReferences', then I could say we may have a DMA allocation problem, but we have a blank stack so there's very little information to get.
7: kd> !irql
Debugger saved IRQL for processor 0x7 -- 0 (LOW_LEVEL)
This seemed to occur at LOW_LEVEL.
DRIVER_VERIFIER_DETECTED_VIOLATION (c4)
This is the general bug check code for fatal errors found by Driver Verifier.
Despite the name of the bug check, Driver Verifier failed to detect a driver within violation.
BugCheck C4, {
f6, 2dc, fffffa8014cdd940, fffff880056ee132}
The 1st parameter of the bug check is
f6 which indicates the user handle was KernelMode. Aside from kernal-mode drivers, file system drivers, etc... Kernel Mode contains the HAL (Hardware Abstraction Layer) > Hardware. The HAL's main function is to hide differences in hardware from most of the operating system kernel, so that most of the kernel-mode code does not need to be changed to run on systems with different hardware. With this occurring at LOW_LEVEL, Kernel Mode, etc, this looks like a hardware issue.
First off, ensure you have the latest video card drivers. If you are already on the latest video card drivers, uninstall and install a version or a few versions behind the latest to ensure it's not a latest driver only issue. If you have already experimented with the latest video card driver and many previous versions, please give the beta driver for your card a try.
-------------------
Start with a Memtest for NO LESS than ~8 passes (several hours):
Memtest86+:
Download Memtest86+ here:
Memtest86+ - Advanced Memory Diagnostic Tool
Which should I download?
You can either download the pre-compiled ISO that you would burn to a CD and then boot from the CD, or you can download the auto-installer for the USB key. What this will do is format your USB drive, make it a bootable device, and then install the necessary files. Both do the same job, it's just up to you which you choose, or which you have available (whether it's CD or USB).
How Memtest works:
Memtest86 writes a series of test patterns to most memory addresses, reads back the data written, and compares it for errors.
The default pass does 9 different tests, varying in access patterns and test data. A tenth test, bit fade, is selectable from the menu. It writes all memory with zeroes, then sleeps for 90 minutes before checking to see if bits have changed (perhaps because of refresh problems). This is repeated with all ones for a total time of 3 hours per pass.
Many chipsets can report RAM speeds and timings via SPD (Serial Presence Detect) or EPP (Enhanced Performance Profiles), and some even support changing the expected memory speed. If the expected memory speed is overclocked, Memtest86 can test that memory performance is error-free with these faster settings.
Some hardware is able to report the "PAT status" (PAT: enabled or PAT: disabled). This is a reference to Intel Performance acceleration technology; there may be BIOS settings which affect this aspect of memory timing.
This information, if available to the program, can be displayed via a menu option.
Any other questions, they can most likely be answered by reading this great guide here:
FAQ : please read before posting
-------------------
If Memtest goes through all ~8 passes with no errors, if you have access to integrated video OR a 2nd GPU... uninstall your video card drivers, shut down and remove your GPU physically (install 2nd GPU if that's your method), turn system on and install latest drivers for either 2nd GPU or integrated video.

Patrick
