Game keeps crashing (without mods or cc)

@yohanafk  On the off chance it helps, please clear Origin's cache and repair the game again.  Sometimes Origin doesn't do a thorough job of repairing, especially when it's cached files related to the game.

Given the errors in your dxdiag, it's a good idea to run a couple of basic checks of your Windows system files:

• Hit Windows key-X
• Choose either “PowerShell (Administrator)” or “Command prompt (Administrator),” whichever option is offered
• Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes into the window, and enter
• The system will start validating soon. If it throws an error, please list it here
• After it reaches 100%, hit Windows key-X again
• Again, choose “PowerShell (Administrator)” or “Command prompt (Administrator)”
• Inside the window, copy and paste “sfc /scannow” without quotes into the window, and enter
• Post the message you receive here
• Restart your computer before trying to play

Please also move the entire Sims 4 folder out of Documents\Electronic Arts and onto your desktop.  When you launch the game, a clean folder will spawn with no content.  Don't add anything to it yet; just start a(nother) new save and see whether it crashes.

If none of this makes a difference, please try playing in a clean boot.

Once you've rebooted, you'll also need to go through the Task Manager's background processes list and shut down anything that doesn't absolutely need to be running.  A lot of programs, anything from MSI Afterburner to RGB software, don't get disabled during a clean boot anymore, so it's necessary to quit them manually.
