Re: video card error
@rakk7012 Please make sure the game is using your Nvidia graphics card rather than the integrated chip. Hit Windows key-i, select System > Display > Graphics settings, click Browse, choose Sims 4 (TS4_x64.exe) from the list, click Options, choose the high-performance option, and save. Make sure your laptop is plugged in and charging when you launch the game as well: when a laptop is running on battery, it can, depending on internal settings, override this choice and use the integrated chip to save power.
If that doesn't help, please go into Documents > Electronic Arts > The Sims 4, open config.log, copy the section under Graphics info (only those ~15 lines; I don't need the rest), and paste it into a reply here.
Please also let me know exactly what the error says, word for word.
By the way, your dxdiag lists a couple of crashes from something called AgreeablebSoft.exe. I have no idea what that is, and neither does google, but if you do, you may want to try closing or disabling it while you play. If you don't know what it is either, you should be able to find it, and a brief description of what it is, in the Task Manager's Details tab.
