My laptop can play Skyrim and Fallout: New Vegas good on high settings but whenever I bought Fallout 3 and decided to play it the fps is horrible, and then we I start the game it always crashes before I can even get to the character creation screen. This has happened to me with two other Bethesda games and it is honestly so annoying and any help is appreciated.

Specs:

OS-Win 7

CPU-Intel Core i3

GPU- Nvidia GeForce GT 555m/Intel HD Graphics

RAM-4GB
