HELP! Sims 4 Constantly Crashing!!

I have the same problem, but when the game crashes, my pc shuts down and turns on again. I also did everything you wrote in the list, and I also started to have this problem after the last patch or maybe a little later when the Reaper Rewards started.. By now I have lost hope 😞

RhiRhiCS melagigante  Please provide a dxdiag.  Hit Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop.  From there, you can attach it to a reply using the camera (Insert Media) icon included with the other formatting buttons.

Yes indeed, I have spent a lot of money on it by buying all the expansions, kit etc., I feel I am being taken for a ride. @ puzzlezaddict here's my crash file

RhiRhiCS melagigante  This is the same dxdiag from the same system.  Are these both your accounts, or are you two different people sharing the same computer?  Either way, it would be easiest to have this conversation with one person/account at a time.

For the issue itself, are you running Sims 4 at a 3840x2160 resolution, to match your monitor; or a lower one?  If you're playing at 4k, please try 1920x1080 instead just to see whether it helps.  Your GTX 970 is still a capable GPU but might be having trouble keeping up with the demands of rendering so many pixels at once.

If that doesn't help, please try playing with your computer offline, just as a test.  You can sign into the EA App and put it in offline mode, then disable wifi and/or disconnect the ethernet cable before pressing Play.  I realize this is not a workable solution, but it is a useful data point.

Well that makes more sense.

RhiRhiCS  Please force the game to run in DirectX 11 mode.  Open your EA App game library, click Sims 4 > Manage > View properties, and add -dx11 in the command line box.

melagigante  Thanks for the extra info, and let me know if you need any more help.

melagigante  Please test again after yesterday's patch, just to see whether it makes any difference.

In general, you should be able to run Sims 4 on ultra settings at 1920x1080.  If you can't, that means something else is wrong, although what exactly that is could be difficult to figure out.

The next step here would be to use a hardware monitoring app to see whether your CPU or GPU is overheating, especially given the age of the system.  I like hwinfo, which lists a LOT of data, but you can ignore most of it for now and focus on only the temperature readings.  Open it before you start playing Sims 4, choose Sensors Only, and check on it when you're done playing (or when the game crashes).  Let me know how hot the CPU and GPU cores get: they shouldn't be above around 90º and 75º, respectively, although a bit more is okay if the temps are stable.

Lowering the in-game settings reduces the load on your hardware, of course, but only if the hardware can't generate higher framerates to compensate.  Sims 4 has a cap of 200 fps, so if you were getting, say, 80 fps on ultra, you might get 120 fps on high (just an example, not actual data) with the hardware working just as hard as before.  That's why it sometimes only helps to lower settings drastically.

melagigante  You'd need to upload the file to a third-party filehosting site and link it here.  Please also post a new dxdiag.  The black screen sounds different.
