All was going smooth : for almost a year now I'd never (or almost) seen my windows crash. After my experience with 98, I thought "damn this XP is stable" ! Now all of a sudden I'm getting total freezing about twice a day. I must have installed something new that's causing the problem, you say. Or maybe I modified my registry one time too many ? -Nope : Simply, I finally got around to visiting windowsupdate.com and applied some security updates.
