Battlefield 4 has stopped working (campaign)

Hello, im having an issue with my Battlefield 4 game, at first i was having graphics stuttering, it was like a small pause of the game every 10 seconds, the game was playable but the stutter was annoying, searching on Battlelog forums someone found a fix and i tried it and the stuttering was gone, i did it with Unpark CPU. After that, i played for like 3 hours with no issue.

Now i went to continue the campaign and after 5 minutes my game froze and went black, i couldnt minimize the game with Alt+TAB, i pressed crtl+alt+delete, clicked on start task manager and i got the error in a popup window "Battlefield 4 has stopped working", i closed it and relaunched my game to continue the campaign and after an hour the same thing just happened. I havent tried multiplayer yet.

I have the lastest Nvidia drivers 331.65, i did repair install in origin for bf4, i deleted punkbuster and reinstalled it (even though this is for multiplayer makes no sense why it would affect single player, but i did it anyways)

I dont know what else to try, is there a fix for this? if someone has a temporary fix or something that can help me with this please post it here.

My computer specs are:
Asus Sabertooth Z77
Intel Core I7 3770k Stock clock 3.5ghz
Corsair Vengeance 8GB 1866mhz CL9-10-9-27 1.5v

Corsair GTX Neutron 240GB

EVGA GeForce GTX770 Classified 4gb

PSU Antec HCP 1000W 80plus Platinum
Windows 7 Ultimate 64bits

Edit: i need to add also when i see the cutscenes that are obviuosly videos and not actual graphics of the game engine, when the videos begin i see the fps counter from dxtory in 22fps and the video cutscene is stuttering after 10 seconds the stuttering stops and the fps goes to 200 fps.
