Game not loading I've tried everything!

ellassmith22​  There isn't anything good that cheap, that is unless you're buying a used system that's several years old directly from its original owner (as on Craigslist or Facebook Marketplace).  I could look there for you, but it's sometimes difficult to know whether you're being scammed, especially in the U.S. with no buyer protections.

If you're thinking about a new computer though, you might as well see whether wiping this one, as in, reinstalling Windows, would help.  You'd be starting over just like with a new system, except it's the same system and you haven't spent any money yet.  Back up your saves and Tray files, or the entire Sims 4 folder they're in (and zip the folder first), then reinstall the OS and see what happens.

I realize this is a burden, and I would still be happy to troubleshoot with you using intermediate steps.  My point here is that if you're not ready to spend the kind of money that would get you a good new computer—and you'd be looking at more like $500, or more for a proper gaming system—this is something you can do now to try to fix the issue.

You can also play on your Mac if you want and if it's from 2012 or newer.  How well Sims 4 would run depends on the specs of the computer, which you can find under About This Mac.  Saves and other user files transfer between Windows and macOS just fine.
