Lenovo Ideapad Y470 + Sims 3 = shuts down suddenly?

I have this laptop for two years, Lenovo Ideapad Y470, and have installed the sims 3 on it. As far as I know, the specs with the game would work fine, but when I open the game, it only loads until the loading screen until 80% then the laptop suddenly shuts down.
I don't know if it is a problem with the game or with the laptop.
Please advise.

Your laptop does not meet the minimum system requirements for the game is why it will not run.
Can your computer run that game?
