>>1484889CCleaner will do next to nothing for video card uninstall use DDU like other anon mentioned if you think it's a driver issue. But I think there is a setting in windows similar to clear text that fixes pixelated text. I can't recall but it might be in desktop theme settings or in the windows display properties. Essentially AA specifically for text within the windows platform and doesn't actually relate to video care drivers. Or you might have the refresh rate improperly set for your display. I recall having this issue years ago bit can't remember how I fixed it.
