13'' early 2011 macbook pro - Crashing issue

My macbook crashes for no apparent reason. It used to work fine but now whenever I watch a show, or a game highlight from NBA or NFL.. it tries to load but eventually crashes to a gray screen. The last time it crashed it showed a folder icon with a question mark. i posted the panic report below... please help!!
