JoiChoi Thanks for the dxdiag, which doesn't show any specific reason Sims 4 isn't working. It does list some generic Windows errors though, so please run a couple of basic checks of your system files:
- Hit Windows key-X
- Choose either “PowerShell (Administrator)” or “Windows Terminal (Administrator),” whichever option is offered
- Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes, 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 “Windows Terminal (Administrator)”
- Inside the window, copy and paste “sfc /scannow” without quotes, and enter
- Post the message you receive here
Restart your computer, hit Windows key-i, select Update & Security, and click the box to check for updates. If any install, restart again afterwards.
Please also tell the game to launch in windowed mode. Open Options.ini, in Documents > Electronic Arts > The Sims 4, search for fullscreen , and set it to 0 (zero). This may fix the issue, but even if it doesn't, it should at least allow you to use the computer in general when the game locks up.
