SPuninstalled KB Patches, still BSOD

After I allowed Windows 2000 Advanced Server to apply several security
updates a couple months ago, I was then greeted with a Stop 0xA "IRQL Not
Less or Equal" for every conceivable start up mode. I put another
operating system on that machine just so I could get at the files.

Recently I've (re)learned how to use the Recovery Console to run the
Spunstall script for those security updates. I've run the scripts for
KB908523 (no change), KB905915 (no change), KB912919 (no change), and
KB908519 (no change). The only one left of the group that were installed
that fateful day is KB829019 (.Net 2.0) and I don't think that could be the
problem.

I'm not sure if I SPuninstalled the updates in the same order that they
were installed. Would that make a difference?

If I recall (and that's fuzzy at best), I also allowed the updater to
install a couple of updated drivers. Now, how do I discover where the old
drivers are that I can rollback to in the Recovery Console? Is this even
possible?

I've already tried a repair install - no luck.

As this was a non-production server used for experimenting and training
only, a backup is/was of no importance.

Any instruction on how to recover from this BSOD will also be a training
experience.

I've thought about disguising the entire System32 and INF directories and
trying another repair install. That might get me away from bad drivers, if
that's what's causing the problem.

Hi;

I think you may be correct about the device driver. The most common one to
cause this is the graphics display driver. Normally I'd suggest you
re-install the latest version of that one (from the OEM website) but since
you cannot log in via any method then I'm not sure how to proceed. I doubt
you will be able to fix that issue via RC.

Have you tried disconnecting everything from the computer except for the
mouse, keyboard, and monitor, and then attempt to boot into Safe Mode? That
might help if the driver is for some other external device. Rarely helps
but maybe worth a shot.

If you "disguise" the System32 and INF folders then it will be much the same
as a clean install versus a "Repair" one; perhaps a side-by-side install on
another partition might be your best bet so that you can then salvage your
data files from the "bad" partition and thus recreate much of what is going
to be lost.
