I have recently been experiencing a bad_pool_header BSOD.
I am running Windows 7 Ultimate 64-bit.
It can be reproduced by opening firefox and navigating to a website, it does not seem to happen if i just leave my computer running.
I have attached the system dumps and perfmon reports.
BlueScreenView is saying that it is caused by ntfs.sys, ntoskrnl.exe, win32k.sys.
Here is some more info that is displayed when the system restarts from the crash:
Problem Event Name: BlueScreen
OS Version: 6.1.7600.2.0.0.256.1
Locale ID: 1033
Additional information about the problem:
OS Version: 6_1_7600
Service Pack: 0_0
