grassgreen17 You did in fact provide the dxdiag correctly, and thanks for that. Most of the Sims 4 errors it lists are generic, but one is the same as what we often see on slightly newer high-end Intel processors. I don't think I've seen yours affected. However, the first step in fixing it is to update the motherboard's BIOS, and yours looks to be quite old, so please do that.
Google "[board model] drivers" and look for the MSI support page. Double-check that the models match exactly before downloading the update.
By the way, did you disable the iGPU in the Device Manager or elsewhere in software? The dxdiag seems to think you did, and although that shouldn't matter since the Nvidia GPU should handle all the graphics rendering, please let me know if you didn't do this and it happened on its own.
If you want to check, click Windows key-X, select the Device Manager, expand Display Adapters, and right-click the Intel listing to see whether you can enable or disable it.
