Yeah, I ran into major problems as a result of this (I gave up and re-formated and re-installed Vista). I tried using the last beta drivers from Nvidia because they were suppose to fix a lot of issues. After I loaded them, the video drivers would crash constantly (I could bairly go 30 seconds without it crashing the video drivers). I was finally able to remove the drivers themselves and go back to the non-beta version, however, I still had problems of the video drivers crashing (not every 30 seconds, but anytime any major graphics change occurred on the screen, like scrolling a webpage, or a new program opening, or video playing, i.e. anything that changed the screen from a static picture into motion it would crash). As I said, I gave up on trying to wipe it, driver cleaner did not help me. I moved all my data off the primary disk only my RAID5 array and formated the OS disk....
