Windows 7: BAD_POOL_HEADER 0x00000019 Need help finding corrupt driver

BAD_POOL_HEADER 0x00000019 Need help finding corrupt driver

One of my clients is getting a Bad Pool Header Error; I know that it's usually either caused by a driver or RAM. I'm remote so I don't have physical access to the computer but I've ruled out RAM because the Blue Screens occur randomly and consistently at least every 10-20 minutes in normal mode, but are completely gone in safe mode. I was able to run a basic RAM stress test in safe mode which found no errors. I essentially just need help determining which driver is causing this error. Windbg tells me it's caused by ntkrnlmp.exe but it's some other program/driver which depends on it. When I used driver verifier, from what I can tell the system crashed and it asked the user to restore windows from recovery. I guided them into Safe Mode with Networking and disabled verifier. I've attached the zip from the forum program.

Windbg gives me this:

Hello mrprez and welcome to 7forums!

3b is usually a graphic's driver (display adapter/video driver), other possibilities include
but are not limited to antivirus/antispyware/security programs and even memory (mapping).

BCCode: 3b 0x0000003b

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.

Please download the graphics driver from Intel here:
Intel® HD Graphics Drivers and Intel® Graphics Media Accelerator Drivers

Then there are a number of crashes the 28th of March but the driver which is blamed is unknown so it's really hard to troubleshoot, the easiest way to find out more about what is causing the crash is to enable Driver Verifier, please follow this guide:
Driver Verifier - Enable and Disable

Cheers, Boris
