There was a power surge, and when I tried starting windows, it said that C:/WINDOWS/config/system32/system was corrupted. I reinstalled windows and specified a different system folder, in the hopes of copying and pasting the corrupted file from the reinstalled version to the old version. (so I wouldn't lose my registry keys and have to reinstall all my programs.) That didn't work. I was completley locked out of C:/WINDOWS, and it said that I needed an admin password, which I didn't have. I decided to leave it and run off of the reinstalled windows. (no files were lost.) However, now, whenever I use IE, Word, or any other application, the scrolling is really, really choppy. Why is that?
