I have a Windows XP machine that randomly freezes.
I can't take a memory dump with manual BSOD even using PS2 keyboard (seems that the machine is so freezed that I can't even provoke a manual BSOD).
In event viewer logs I don't see any errors, just normal activity until the freeze time, and then usual boot-logs when I force an hardware reboot.
The issue might be related to Sygate Personal Firewall (SPF) (tucows.com/preview/213160). I don't know if it's only a coincidence, but freezes started after the installation of this software, and removing it seems that no more freezes are happening.
Any idea on how to identify the software / driver freezing the machine or conflicting with SPF would be appreciated!
