If its the serp belt, its likely that one of the pullies seized. My first guess would be the idler pulley, as there's a TSB about it. Both of my Duratecs had the problem within the last year, and each of them had some ticking or scraping noises, but I caught it before anything seized each time. You can buy an updated pulley with better bearings from Ford. The repair is pretty straightforward.
