Sims 3 Stuck at loading screen (again!)

@Aptmass  Sorry for the late response.  There's still some strange information about your graphics card drivers, so it's best to do a clean uninstall of both drivers.  Instead of merely updating, this will remove all traces of the previous drivers before installing the new ones.  Here's how to do it:

First, download Display Driver Uninstaller from here:

Please download your drivers directly from the Dell support page for your computer.  Click "Show all 45 Downloads," and scroll down to the bottom, to where the Intel and Nvidia video drivers are listed.

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 (ctrl-C) and then paste it (ctrl-V) 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:

Choose GPU, then Nvidia, then click Clean and Restart.  Your computer will restart in normal mode.  Launch the DDU again, reboot into Safe Mode, and repeat the above steps, but this time, choose Intel instead of Nvidia in step 2.

After your computer reboots into normal mode, still offline, you can install the Intel driver, then reboot, and then install the Nvidia driver and reboot again.  For the Nvidia driver, choose a custom install, and only install the driver and the PHYSX software.

If it helps, you can print this out, since you won't be able to go back online and have a look until you're done with the whole process.
