Sims 3 Crashes to Desktop with No Error Message!

@tbluitt2326  Okay, I think it's time for a clean install of your graphics card drivers.  Here's how to do it:

First, download Display Driver Uninstaller from here:

You can download fresh drivers (start with Intel VGA) here:

https://www.acer.com/ac/en/US/content/support-product/7571?b=1

Next, take your computer completely offline—disable wifi and/or pull the ethernet cord—and double-click the DDU.exe.  Take note of where the file will land, and click Extract.  If it's easier, you can copy the path and then paste it into the address bar in a File Explorer window.  Open the folder and then Display Driver Uninstaller.exe, and you'll get a message that you're not in Safe Mode.  Click OK, then go to Options and enable Safe Mode dialog.  Here's a screenshot of what your options should look like:

Close options, and the DDU, and then open the DDU.exe again.  For launch options, choose "Safe Mode (Recommended)," and then click Reboot to Safe Mode (you'll need your password, so find it before rebooting).  Once you login, you'll see this:

Choose GPU in the dropdown menu (step one), then Intel (step 2) if it's not already showing.  Then click Clean and Restart (step 3).

Once your computer has rebooted, now back in normal mode, run the driver install .exe in custom mode. Select "perform a clean installation" and install ONLY the GPU driver and the PHYSX software.

Reboot after the install, and then repeat the process for the Nvidia VGA, also from the Acer site.

Reboot again, and then you can start testing the game.  If it crashes, look for a dump file again, and please run another dxdiag.

(Also, thanks again @holger1405 for the tutorial, with pictures and everything.)
