Google brought me here related to a search on my bad_pool_caller issue I keep experiencing periodically. I have yet to narrow it down to a particular peice of hardware or software and am hoping someone can review my latest MINIDUMP to point me in the right direction. The PC is a few years old, no new major hardware changes that I recall except one internal hard drive, but I am constantly installing/uninstalling software.

The BSOD references no particular driver or other specific info other than what's also loggedin EVENTVIEWER.

Code:

The computer has rebooted from a bugcheck.  The bugcheck was: 0x000000c2 (0x00000007, 0x00000cd4, 0x02060001, 0x866503f8). A dump was saved in: C:\WINDOWS\Minidump\Mini020707-01.dmp.

That specific DMP is attached for your review.

Thanks.

And now that I've already posted I'm actually reading the "...before you post DMP files..." message at the top of this forum.

Your debug report and the culprit is Zonalarm

Refer this problem and it is identical to your problem. De-install or upgrade ZA will fix the blue screen problem.

Interestingly I had disabled, but not uninstalled, Zone Alarm when the problem first appeared. It had never found any malware/etc. and I have a hardware firewall/NAT anyway so virtually everything is stealth and protected. I'll uninstall ZA, reboot, and see what happens.

Many thanks for deciphering my dump and ending the mystery.
