Im sick of going into the leaderboards only for them to freeze up my ps3 what the hells goin on? When it freezes I can press ps button , go to quit game and when I do instead of taking me to the xmb it switches off my machine . Wtf? My ps is brand new is anyone else experiencing this? I'm concerned. As mw2 gave me YLOD  after 2 months play . This has happened at least a dozen times an twice today. And it only happens when i go to the leaderboard.
