I see you are still having problems.
I'm referencing back to your resolution problem thread.
Have you considered or done a Repair Install? Repair Install
Just a thought but there might be a Windows registry error that occured with uninstalling ATI drivers
and installing the Nvidia's etc.
I know it is annoying to you.
It is me also that it hasn't been resolved.
Something to consider if you haven't tried it yet. You may have and I forgot.
Otherwise I haven't found anything new.
