I analyzed my recent BSOD and this came up:
On Fri 2012-02-03 18:24:16 GMT your computer crashed
crash dump file: C:\Windows\memory.dmp
This was probably caused by the following module: inspect.sys (inspect+0xCE76)
Bugcheck code: 0x19 (0x3, 0xFFFFF80002E14310, 0xFFFFF80002E14310, 0xFFFFFA800A43D198)
Error: BAD_POOL_HEADER
file path: C:\Windows\system32\drivers\inspect.sys
product: COMODO Internet Security Firewall Driver
company: COMODO
description: COMODO Internet Security Firewall Driver
Bug check description: This indicates that a pool header is corrupt.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. This might be a case of memory corruption. More often memory corruption happens because of software errors in buggy drivers, not because of faulty RAM modules.
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: inspect.sys (COMODO Internet Security Firewall Driver, COMODO).
