it is a driver issue caused by nvidia GPU in vista.try updating latest drivers.
Never heard about the problem in Win 7!
I have updated the drivers, and still get the error. It also happens with ATI cards. ATI users get "atikmdag". I've tried most of the possible fixes on this website http://www.nvlddmkm.com/
to no avail.
But good to know that it's vista related
