Sometimes when you're removing something from your computer, say you're putting in a new video card and don't need the old drivers anymore, the old files aren't always removed properly. Luckily for us someone else noticed this too only he wrote a program to fix the problem - tell it what drivers you had before and it'll make sure all of the remnants are promptly given marching orders, and its completely free.
