Randomly occuring 0x19 BSOD on boot

[overfocused]

I currently get a randomly occurring 0x00000019 BAD_POOL_HEADER stop error that 9 out of 10 times does not occur on boot. When it does, however, it concerns me to know what is going on with my machine the 1 time out of 10 it happens to fail to boot. I have never gotten a BSOD on this machine once it has successfully booted into the OS, so it happens only during boot. According to BlueScreenViewer it happens when loading the network driver/service 'RAS SSTP Miniport Call Manager' so I tried updating, then uninstalling all LAN drivers to update them, and even tried a different LAN card (I have a couple lying around) and it still happens. The service is already disabled so I'm not sure why loading a .dll that isn't going to be used could crash the system randomly. Below is the shortened analysis given by BlueScreenViewer, and I've also attached the minidump to this post. Thanks!

Hi overfocused and Welcome to The Forum.


STOP 0x00000019: BAD_POOL_HEADER
Usual causes: Device driver.

Your latest dump file lists Pool_Corruption as the probable cause which usually indicates bad drivers.
Old and incompatible drivers can and do cause issues with Windows 7, often giving false error codes. Random stop codes can often indicate hardware issues.


As a Priority:

cmdguard.sys Fri Oct 07 18:30:25 2011 COMODO Firewall Pro Sandbox Driver. Not seen before but is mentioned in your dump file. You might want to consider removing Comodo Firewall and running with the more than adequate Windows Firewall until you are blue screen free. You can then re-install Comodo to see how it goes.


Drivers that pre-date Windows 7. Update:

Rtnic64.sys Fri May 30 16:12:23 2008 Realtek Ethernet NIC driver

SI3132.sys Wed Oct 03 19:39:29 2007
SiRemFil.sys Wed Jun 20 20:42:10 2007
SiWinAcc.sys Fri Jun 15 01:02:02 2007 Silicon Image drivers.
