@lianelianeliane  Please move your entire Sims 4 game folder out of Documents\Electronic Arts and onto your desktop.  When you launch the game, a clean folder will be created with no content.  Don't add anything to this folder; just start a new save and see how it runs.  Let me know whether you still get crashes, and how long you can play.

If you do get more crashes with the clean folder, please run a dxdiag and attach it to a post.

Great! Now all of my Sim 4 worlds have been erased. 

@lianelianeliane  Your worlds aren't erased—the save files are still intact in the folder you moved.  You can transfer your saves back later, once you get the crashing under control.   For now though, the point is to see whether a brand new save in a completely clean game folder runs better.  There are so many causes of crashing, it's necessary to narrow things down before making any troubleshooting suggestions.

Let me know how the new save runs in the clean folder, and if it still crashes, please run a dxdiag and attach it to a post.

It didn't crash.

@lianelianeliane  Okay, that's great news.  Now you can start transferring your mods to the new folder in batches, testing each time.  If you get another crash, you'll need to split the last batch of mods you added and test again until you find the problem file(s).  You can do the same for your custom content.  (If it's easier, you can just download updated versions of everything you can find rather than hoping the old versions still work.)  Once you've removed the corrupt files and confirmed that you can play with the others with no crashing, you can copy your saves to the new folder as well.

In  case it helps get you oriented, here's an explanation of all the files in your game folder:

I just realized that the game is crashing even when I don't have mods or CC, so here is my dxdiag.

I'm new to this, sorry.

@lianelianeliane  You're fine; I know this process can be difficult to navigate (and this site as well).

Since you have Windows 7, your dxdiag doesn't list any error reports.  So please gather that information from the Reliability Monitor.  Hit Windows key-R and enter "perfmon /rel" without quotes.  A graph will show up with an entry for each day.  For the last two days, look for any entries that mention Sims 4 or Origin, or any that have timestamps that correspond to when the game crashed.  For each one, click "View technical details" and copy the information you see into a text document (Notepad works fine).  You can attach the .txt file just like you did the dxdiag.

I only copied and pasted 1 from each day, so I don't know if I did this correctly.

@lianelianeliane  You got exactly the right information.  Most of the errors aren't really specific, although one does reference DirectX 9.  If you're running RivaTuner Statistics Server or MSI Afterburner alongside the game, please disable it, and test, just to be thorough.

If that doesn't help, please reinstall DirectX 9.  You don't need to uninstall your current version; just download the installer from Microsoft and run it.

If that doesn't help either, please update your graphics card driver, which is from 2016.  Be sure to get the 64-bit version, since your Windows 7 runs in 64-bit.

Let me know if none of this helps.

It's still crashing, sadly.
