@kittell17 Alright, if there's nothing related to the Sims 4 crashes in the Reliability Monitor, then don't bother trying to upload the reports. If you do see Sims crash-related info in the future, you can highlight, copy, open Notepad, paste, and it should automatically save as a .txt file. Or you can past the text into a reply here, but please use a spoiler.
The next step here though is hardware monitoring. Please download hwinfo from here:
https://www.hwinfo.com/download/
You don't even need to install anything: just download 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, open hwinfo, choose "sensors only," and click the icon that's a sheet of paper with a + sign to start logging. Save the log file to your desktop or somewhere else convenient.
Wait five minutes, then open Origin and Sims 4, and play. Don't open anything else. Normally, I'd say play for 20 minutes or until you get a crash, but if this issue is intermittent, hwinfo might not pick up the problem until it actually shows up. So just play normally, and if you see a problem, quit and end loggind by clicking the same icon. If there aren't any issues, you can trash the log and get a new one the next time you play.
Upload the log file to a third-party free filehosting site, and link it here. Please leave it in .csv format, unless you use OneDrive to upload it, in which case zip it up first.
