That's probably what I'll end up doing with my older PC. The hard drive is all messed up from old viruses, goofey program installs/uninstalls, power outages, crashes, etc -- past due for a wipe! It's an old 40GB anway, and I'd like to upgrade to an 80GB, so that would be a good time to reinstall Windows.
