XP Fail

My XP install is effectively hosed. Complete failure to boot (fixed with some knowledge and a *lot* of luck), all copies of UPP considered viruses (including archived and untouched copies), failure of windows update, not to mention several long-running issues involving mysterious cpu/disk usage (not virus related afaict) and random crashes (graphics related but not app or driver version specific).

I read from the Book of Ripley: "I say we take off and nuke the entire site from orbit. It's the only way to be sure."
