I always, always, always recommend using
MemMaid or
SKTools as some 3rd party programs aren't very good at uninstalling themselves and leave junk behind. These programs will find all of those registry entries, leftover shortcuts, orphanced files, etc. Sktools also has a whole assortment of other tweaks and functions to make your 6700 hum at top speed with no errors or problems. Give 'em a shot.
damn, wideawake beat me too it...lol
