Civ 5 random freeses

[apocalypse105]

When i start civ 5 i have the brave new world loading screen with gods and king music. I can play the game normally for about 60 minutes and after that he freeses and i cant do anything.. Someties it crashes even after 30 minutes

Does anybody have the same issue?

I recently have trouble with installing civ 5 this topic but that isnt a problem anymore :
