I have win xp pro and things are starting to "not work" so I think it's time to reload. One of the things that isn't working is my dvd burner (well, it works sporadically) so backing up is nearly impossible. I'm thinking about buying a new hard drive, formatting it and installing xp and then taking the old drive, backing it up and then formatting it and reinstall programs and data on it (and leave the os only on the new drive).
