iTunes is restarting Windows XP almost everytime I start it up. Even if I just open iTunes and do nothing else, it will restart windows within a few seconds. I am running the latest version of iTunes on XP SP1, with a P4 3.2GHZ, 512RAM. Nothing else is open when this happens. Is anyone else having this problem? Any ideas to fix it?
