You could pull the belt off and roll the pulleys by hand checking for roughness/play/unusual feel.

Before that though, I would check the belt tension....they tend to make noise when they get a bit loose. You would swear its too tight when you have it tightened good.....

Oh yeah and welcome to CF!
