Slim is slower than usual,freezes sometimes, having game glitches I’ve never had, characters talking 5 seconds after I see subtitles and taking longer than usual to load graphics, longer load times, and game glitches that I never have seen before, over the past few days I’ve noticed it has gotten slower. Today it’s the slowest it’s ever been, tried the basic, off n on, rebuilding database, deleting some stuff from storage still same problems
Unfortunately it sounds like your apu is on its way out. I would recommend backing up all your data and either buying a new ps4, or contacting Sony because replacing the apu is impossible without specialized equipment.
