Hi. THanks for your input. I have tried these various ideas for resolving
this issue but I am still int he same situation.

Right now I have my machine running but it is without ANY installed driver
for my NVidia card. Therefore I only have very basic display functionality.
Whih at least allows me some more tools to troubleshoot the problem.

If I try to install any driver whatsoever then I get the same nvlddmkm.sys
error on boot. I've tried about 7 different drivers. Each time same thing.

ANy more ideas people?
