My ps3 is a slim 250BG I cleaned it restart system everything. Now the problem is my ps3 freezes for a couple of seconds and resumes fine in game and menu sometimes I would play zombies and it freezes 20 seconds later I find myself dead . I'm on psn menu and I'm scrolling looking at my friends it just stop for a couple of seconds and resumes.

I even tried playing digital and it still happens I would play watch dogs and the characters would glitch during video play and when I'm driving the music will stop playing like if it's buffering although when I play it's fine runs smooth I kill people easily fine and then one day it just froze completely while playing when I exploded a lot of grenades in watch dogs
