Windows XP Service Pack 2.

I've used the Automatic Updates to finally get all updates. No change.

It's gotten so bad now that nothing via IE works. I can't run my ASP.NET apps, I can't go to hotmail, yahoo mail, or pretty much any site. It's just dead. I've uninstalled and reinstalled, cleared my drive, repaired the installation, removed program after program, shut down everything at startup - I'm out of options. I guess a reformat is my only choice left.
