Missval22 Do you still get the same kind of crash you described earlier: black screen, fans get very loud? Or is there a difference? And does it help to play in windowed mode, or to switch to DirectX 9 mode? Both are options in the graphics settings.
If those don't make a difference, I'd like to see the results of some hardware monitoring on this computer. Please download hwinfo (it's free) 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 or your computer 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 computer does crash, the log should be intact up until 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.
MoistestBagel0 Please try the suggestions in the thread I made for you here, and use that thread for any further help.

JanieBaer Please test with no mods or custom content, if you haven't already. You don't need to save your progress. If that doesn't help, please create a new thread in this section describing the issue in more detail, or post screenshots.
