Missval22 Are you still seeing the same kind of crash: screen goes black, fans get noisy? If not, please let me know what happens.
Either way, I'd like to see the results of some hardware monitoring on this computer. Please download hwinfo from here:
https://www.hwinfo.com/download/
You don't need to install anything; just choose the Portable version, unzip it, and launch it from Downloads or wherever you like. If you do want the full installer, be sure to click the button for hwinfo itself, not for lansweeper.
Restart your computer, open hwinfo, choose Sensors Only, and click the button that's a sheet of paper with a + to start logging. Save the log file to your desktop for easy access. Wait five minutes, then open Sims 4 and play until it crashes. Don't alt-tab out of the game or run any other programs, aside from the EA App of course, while you're testing. When you're done, click the same button to stop the logging. If your entire computer crashes, the log should still be intact up to that point.
Please upload the log to the third-party filesharing site of your choice (Google Drive, Dropbox, etc.) and link it for me. Either leave it in .csv format or, if you're going to use OneDrive, create a .zip file, and don't open the log before uploading it, or else my log reader might not be able to interpret it.
