Re: Sims 3 : Screen suddenly goes black when I play game for a while

@srpnizz  This particular error is an access violation, meaning that Sims 3 tried to access a memory address in a way that's not allowed.  When Windows detects this behavior, it shuts down the application.

The issue is that access violations are extremely common and a very broad category.  They can be caused by anything from bad mods or custom content to an in-game bug to going over the game's memory limit to a hardware issue with your computer.  The place to start is with mods and cc: if you currently have any at all other than NRaas mods, remove all the content and see what happens.  That can include cc that you've used for a long time—an item might only become a problem when it's assigned to the wrong sim.

Please also let me know what was happening in-game when you got the black screen, not only that you were in live mode but what your sims were doing and what sim-time of day it was.
