I know it must be something else. But I cannot for the life of me figure out. It only happens when I am in Facebook, while using chrome. Has never happened using Facebook in Firefox, nor when I have used something other than Facebook. And I have had it going for a good 7 or 8 hours.

It is not every time I use Facebook, but does seem to be tied when I have scrolled through a few times. I am wondering if it is somehow tied to a post or one of Facebooks oh so helpful (sarcastic) suggestions. I have found nothing in event viewer.
