I've had not stop crashing since redownloading the game. I have tried all the following troubleshooting steps to no avail:
I'm wondering if it's because I'm running DirectX12. Anyone have any advice?
RiverRaide2591 DirectX 12 is backwards-compatible with previous versions, so no, that's not the issue. Most of the Sims 4 crashes in your dxdiag point to the Nvidia graphics driver though, so the place to start is with a clean uninstall and reinstall of the driver. Here's how to do it:
If you get another crash, look for a BIOS update on the support site for your motherboard. Your dxdiag doesn't list the board, so I can't look myself, but googling the model number should take you to the manufacturer's support site. If you do find a new BIOS version, follow the instructions to install the driver and see whether it helps.
If that doesn't make a difference, or you don't have an available BIOS update, please look for new errors in the Reliability Monitor. Hit Windows key-R and enter "perfmon /rel" without quotes, and you'll see a chart of errors and updates with a column for each day. Today is on the right.
Look for an error that happened at exactly the time of your most recent Sims 4 crash. If you find one, double-click it to see more details, then copy that info and paste it into a reply here. If you don't see a new error, check back in an hour or so—the Reliability Monitor doesn't always update right away.
