Sims 4 Inoperable On Startup

@Sagittarius1227  Please run a dxdiag and attach it to a post.

Alright, I've done that.

@Sagittarius1227 First thing I notice is you have an Intel alder Lake cpu. There is a DRM issue with this cpu that causes some game not to run. I thought there was a game patch or OS fix. You'll have to search for a solution.

@Sagittarius1227  It looks like this issue may be related to the driver for your graphics card.  Intel dedicated graphics and Sims 4 seem to not work that well together, at least some of the time—you're the third or fourth person I've seen with exactly what's in your screenshot and an Intel discrete GPU.  But still, the first step here is to clean-uninstall and reinstall both drivers.  You can download fresh copies from Lenovo:

You'll specifically need the Intel DG2 driver and the  iGPU driver.  Download both before starting, then go through this process:

Display Driver Uninstaller should remove both Intel drivers at the same time, but please open it again after the first run and make sure it isn't still seeing a graphics driver present.  Once both drivers are removed, run the iGPU installer, restart your computer, then run the DG2 driver and restart again.  Stay offline for the entire process.

@roberta591  The Alder Lake issue affects Sims 3, not Sims 4, and it prevents the game from even starting to load.  It doesn't glitch out the screen while the game is loading.

Thank you for your help!

@puzzlezaddict I do not know much about how computers run, so I am a little worried: will reinstalling the graphics card affect the graphics of other things I have installed, such as Clip Studio Paint?

@Sagittarius1227  You're not reinstalling the graphics card, you're reinstalling the graphics driver, which is just software.  Uninstalling it doesn't remove any other software from your computer.  The program recommended in the guide I linked is very precise about what it removes.

I tried what you recommended, and I am still having the same problem.

@puzzlezaddict 

I tried Fullscreen Mode = 1 with the Intel DG2 driver and the iGPU driver before I downloaded the WHQL Driver, and the graphics actually worked. For whatever reason, they don’t work in Fullscreen Mode = 0.

With the WHQL Driver, the graphics (and the game) worked in Fullscreen 1 and 0.

Thank you for your help!
