game stuttering and freeze

lately the game has been freezing like crazy , whenever I log in to play I wait for like 5 minutes for the map , npc and even players to load , then whenever I use hearthstone or any action that leads to a loading screen the game completely freezes , that I have to close it from task manager (it says world of warcraft 3.3.5 not responding) and spam alt F4 multiple times , I tried /reload ui , updating my drivers , defragging my hard discs, disabling/enabling all the addons , setting all graphics to low and disabling vsync and hardware cursor , even uninstalling the game and reinstalling it , the game is always freezing randomly , please help and thank you.

It's possible the storage drive your game is on is defective and has to be replaced. Test it with something like Victoria or HD Tune, or let someone savvier do it.
