Sims 4 Using Up all my RAM

@smilelikemiles  A repair install doesn't take much time, maybe ten minutes or less on your computer.  And you can back out up until the final steps, where you're asked whether you want to keep personal data.  If you don't want to do that at the moment, that's fine, but even installing more RAM won't fix the errors in your dxdiag, although the extra memory may disguise the problems somewhat.

I would still like to try to help if you're interested, and I'm here every day, almost always multiple times a day.  At the very least, it's worth finding out what else is starting with Windows, because as I said, the system shouldn't be using nearly that much RAM on startup.  Mine uses a little more than 2 GB, and I haven't done anything special.

Additionally, updates to apps or even Windows can change the settings, for example Edge decided to start with Windows after a recent generic Windows update, which I didn't know until I happened to check the Task Manager and found it running.
