This appears to be a new build, correct? Is this also a clean install of Windows?
BTW, I hope you did a thorough job of removing the old ATI drivers before installing the nVidia drivers. ATI has a tool you can download from their site that helps you do this. Not following through on this can lead to issues.
Also, what games, or game, are you playing that causes the restart? There could be issues with the game itself and certain (or all) drivers and a patch may have been released for it.
Also, were you controlling AA from the ATI driver, or from the game?
