Vista Update Nvidia Driver nvlddmkm.sys BSOD

August 27th, Vista Ultimate 32bit, Nvidia 7600GT, 4Gb Ram

My Vista Ultimate system has an XFX NVidia 7600GT card in it. It has been
working fine since the day I put it in. My system is always on and I usually
let it update automatically via Windows Update as required.

The other day I came home from work and began to notice a degradation in
graphics quality. There were artefacts on the desktop and things were, well,
twitching… I became concerned and then I noticed that Vista was recovering a
crashed Display Driver repeatedly (first I had ever seen that) and then I was
really concerned. I had not updated or changed anything myself so I started
to check Windows Vista Update to see what it had updated in my absence. I
only managed to begin to see that Update had downloaded or started to
download, among other things, an updated NVidia driver..

I never got a chance to fault find any further since my system then became
so unstable the graphics went for a loop and I could not make anything out on
screen. Next thing it somersaulted into a BSOD blaming nvlddmkm.sys

Now my system will not boot up and immediately crashes with a BSOD every
time blaming nvlddmkm.sys – an nvidia display driver. The only way I can get
into my system is via safe mode and it has limited tools, particularly, it
does not allow access to Windows Update for me to check what Update did, what
it installed etc etc

I don’t know the version of the driver that was working fine previously. I
had never updated it since the card went in and it has worked fine ever
since, that is until this recent event. I don’t know what version Windows
Update tried to install because I can’t check it out.

What I’ve tried:
Installing a variety of updated drivers from NVidia Website including a
beta, from Safe Mode in Vista: no result, same BSOD
Rolling back driver to previous: no result, same BSOD
Using Sys Restore in Safe Mode to jump back to a previous known good
position: no result, same BSOD

Basically my system is trashed because Update downloaded some monster driver
that screwed up my system. Usually I’m pretty good troubleshooting and fixing
these kinds of things, I work in IT, but this one has me stumped. I have no
idea what Update did and feel I have exhausted my troubleshooting options.
Can anyone help me? Thanks.

You should be able to go to Control Panel/uninstall programs and uninstall
the nVidia driver there.
