I have the 120 gb ps3. ive had this since april. Today my controller started vibrating uncontrollably. I held the reset button in and it didnt help. It quit vibration for about 3 secs then picked up again. Then the thing wouldnt connect until i plugged usb charger in. Then i was in the first 2 mins of a mw2 game and it stops working. How do i fix this?
