I’ve had a reliable case of the BSODs since the reinstallation, and after some consultation on TechGuy (see the full story at http://forums.techguy.org/windows-nt-2000-xp/857774-bsod-errors-happens-w-o.html), it appears Comodo is referenced in the BSOD minidump files (available via the TechGuys thread). I’d be grateful for your feedback to know whether I’m encountering a misinstallation, a software/driver conflict, or something new and as yet unidentified.
I made a x-ref to that forum earlier in the day. I kept getting BSODs after uninstalling CIS, which I presume is a reliable indicator that CIS is not the problem. Minidumps are an imperfect picture, I guess.
As for the error message, it doesn’t give one. The machine simply flips to black instantly. Upon restart, I get a “serious error” message, followed by a browser window that leads to a nondescript error message suggesting a driver, virus or hardware problem. (“Thanks, MS, for narrowing it down to a software or hardware problem!”)
