Sims 3 Crashing Randomly During Gameplay

@NoLoveDeepT  Your computer's graphics driver is somewhat old, and it's a good idea to update it.  You can get the newest driver from Nvidia:

https://www.nvidia.com/Download/driverResults.aspx/209129/en-us/

Run the installer as an admin: right-click the download and select "Run as administrator."  Select the Custom (not Express) install option, and check the box to perform a clean install.  Restart your computer when the process is finished.

For the Sims 3 issue, please try playing a new save in a clean user folder so we can find out whether the problem is related to your in-game content or something else.  Move the entire Sims 3 folder out of Documents > Electronic Arts and onto your desktop.  If you get an error when trying to move the folder, or it duplicates instead of moving, stop here and let me know.

Otherwise, when you launch the game, a clean folder will spawn with no content.  Don't add anything to it yet; just start a new save and see whether the game crashes.  If it doesn't, copy over your save, but nothing else yet, and test that.  Since you're copying rather than moving the save, you don't need to worry about the effects of missing mods and cc—the original save will still be intact in the old folder while you experiment on the new one.

If the game is still stable, you can start adding back your mods and custom content a little at a time, testing along the way.  Please do not use CC Magic or any other mod organizing tool, at least for now, just to keep things simple.

If the game crashes at any point during this testing, stop there and let me know the context of the crash, both where you were in the testing and what you were doing in-game at the time.
