What about the other 1.1% - I think if you have any beef with a particular driver then you should reinstall or look for an update and in the case of NVidia, you should always download those from your computer support site as vendors tend to OEM modify them - so if there's any fault, that could be laid at the door of the computer vendor, but any files that are downloaded are essential for a component to work.
Imagine we have done all that, but after a re-install. only using windows drivers worked great, but then later it found that using the Nvidea 9800 Board, it updated to that...
imagine that.
in my case
