Sims 4 : Black Screen at startup but still music and the mouse

@Ibtissims  Please save all the information in the dxdiag as a .txt file—click on "Enregistrer toutes les informations" and save the file to your desktop.  Then you can attach it to a reply here.  There's a lot more information in a dxdiag than what's on the page in your screenshot.  And it's fine that it's in French; the relevant information is easy enough to find in any language.

Please also remove your Sims 4 game folder from Documents\Electronic Arts.  (You can just move it to your desktop.)  Try to launch the game, and let me know whether it works.  Your saves won't show up, but that's fine, since they'll still be in the folder you moved, and you can always put them back later.
