@Bts152 I meant that it might be helpful to switch back and forth between fullscreen and windowed modes, to see whether the game looked better in one than the other. It's possible fullscreen mode will take care of the issue.
If it doesn't though, please try playing with the Alienware Command Center disabled. You can just kill it in the Task Manager: hit crtl-alt-delete, bring up the TM, find anything with "Alienware" in its name in the background tasks, and End Task. It will restart the next time you reboot your computer, but in the interim, it shouldn't affect how Sims 3 runs.
Origin is also throwing errors, so it's a good idea to clear its cache, uninstall it "the hard way," and reinstall. This shouldn't affect any of your installed games.
