Re: The Sims 3 crash inside CAS without error message
@YFloover Most of the Sims 3 errors in your dxdiag are access violations, meaning the game tried to access a memory address in a way that is not allowed, and Windows crashed the application. This can have a number of different causes, including poorly made custom content, so it's not always obvious what the problem is.
To that end, start with the basics: clear Origin's cache, restart your computer, and repair the game: open your Origin game library, right-click on the Sims 3 icon, and select Repair. If you've taken steps to get your graphics card recognized, please put aside copies of the two .sgr files before repairing, so you can put them back later—the repair will return those files to their original form. Leave the files in their default condition for now though. Having an unrecognized card shouldn't exacerbate the crashing, and it's easier to troubleshoot with fewer factors to account for.
One of the errors in your dxdiag mentions a component of the 2005 VC++ runtime, which Sims 3 uses. So it's a good idea to uninstall it and install a fresh copy from Microsoft. Hit Windows key-i, select Apps, and scroll down to where the Microsoft Visual C++ Redistributables are listed. You want the 2005 x86 version; ignore the x64 version if you have it, or the versions from any other years. Click on it and select Uninstall. Then you can download a new copy from Microsoft here:

You only need to install the x86 version, not the others. Restart your computer before testing.
If you get another crash, please test in a clean user data folder. Move your entire Sims 3 folder out of Documents\Electronic Arts and onto your desktop, and when you launch the game, a clean folder will spawn with no content. Don't add anything to this folder yet, not your saves or sims and definitely not your custom content; just spend some time in CAS and see whether the game crashes. Let me know either way.
It should also be noted that your dxdiag lists a few crashes of Alicia.exe. I don't know how to troubleshoot the game, if you're playing it, but if you're not currently, you'll want to uninstall it completely.
