@mashmusen Dump files can get deleted after some time, or sooner if you have a cleaner app that deletes temp files. If you do, please disable or uninstall it for now—it's better to be able to find the relevant extra files than to keep your hard drive free of clutter, at least while troubleshooting.
The quickest approach to locating any dump files is to open a File Explorer window and search for *.dmp and *.mdmp (the asterisk, then the file extension). which should turn up any of either kind. Make sure File Explorer is set to show hidden files and folders; I'm not actually sure that matters when searching, but it's an easy setting to switch back and forth.
If you don't find anything though, it's not necessarily a sign of a problem. The dxdiag doesn't include dates with its errors, so there's no way of knowing when the USB driver errors happened. And those errors aren't likely to cause a restart anyway. Whether you find any dump files or not, it's a good idea to do some hardware monitoring, to see whether there's anything obviously wrong with any of your components. Download hwinfo from here:

You don't need to install anything if you don't want to; just choose the Portable version, unzip it, and launch it from Downloads or wherever you want. (If you would like to install, be sure to click the green button, not the orange one.) Restart your computer, and don't open any other apps. Launch hwinfo, choose "sensors only," and click the icon that's a sheet of paper with a + sign to start logging. Save the file to your desktop for easy access later.
Wait five minutes, then launch Sims 4 and play for however long you want, but at least 20 minutes. If the computer doesn't restart, you can click the same button to end logging. Even if it does restart, the log should be intact up to that point, but please let me know whether your system restarted or not. Upload the log to a third-party free filehosting site and link it here. Please leave it in .csv format, or if you use OneDrive to share, please compress it in .zip format instead.
