Well, the first time I posted I thought it could have been caused by IE7. Well, I did a drive image of my clean XP install with my bare minimal programs. Before I did any updates, I noticed that I was still getting the 100% cpu usage. First off, I don't think so, but is there any chance the drive image messes up things? I noticed that when my system rebooted windows did a disk check for errors, which turned up fine. I was thinking about doing a clean install, but if the above works fine, I really don't want to have to go through it. What you guys think? maybe hardware problems starting to shop up?
