Before i got a new graphics card, my Far Cry 3 was working perfectly fine. Then, i switched my card to the NVIDIA GeForce GTX 650 Ti SSC 2GB and now, whenever i start the game, meaning when i click on resume game from last save, it shut my PC down as if i unplugged it. Only Far Cry 3 does this, and i have no clue why. I can play GTAIV and Black Ops 2 perfectly fine, but this game will not run. Only at certain times after a restart, i can get the game to run for about 30 seconds until it shuts down. Why is this happening?

This might not help but try changing the graphic settings maybe? Like,Resolution and few other crap..

Uh, do you have both cards inside your PC ? Have you tried running it from a fresh install ?

far cry 3 co-op work on cracked version?

I was using the install that i had with the previous PC and i dont see why it would help to re-install. I would have to redownload the game. And i only have this new card in the PC, not both.
