Re: Sims 4 Shows a White screen, then Instantly Crashes.
@foolspark Your dxdiag says Sims 4 is crashing because the AMD driver is crashing and taking the game down with it. Dell offers a newer driver for your laptop that covers both the integrated graphics chip and the dedicated card. You can get it here:

You're looking for the AMD Radeon Graphics Driver, in the Video category. Run the installer as an admin: right-click the downloaded file and select "Run as administrator." Restart your computer after installing and before trying to play. If that doesn't help, please post a new dxdiag.
