Re: My Sims 4 game keeps closing randomly
@Krysten71 The driver for your graphics card is a year old, so it's worth updating. You can get the newest driver from Nvidia:
https://www.nvidia.com/Download/driverResults.aspx/224483/en-us/
Run the installer as an admin: right-click the download and select "Run as administrator." Choose the Custom (not Express) install method, and check the box to perform a clean install. Restart afterwards and before trying to play.
If that doesn't help, please let me know what graphics card you had before. Please also make sure the card is seated properly in the PCIe slot and the 8-pin supplementary power connector is firmly attached too. It should click into place, and it's worth disconnecting, blowing out the slot and connector, and reinserting.
