Maby it is because of your processor... Assassin's creed recommed a dual one. But i don't know lots of things about computers...

your entire system is under the min requirements. your CPU is a single core CPU and actualy a low speed one. also your ATI X1600/X1650 is running on AGP when the game requirements says that them two cards must be the PCIe version. so to me it looks like there isnt anything you can do and you should of read the min requirements before buying the game.
