EA reset

2lprkkexmhsh​  There's nothing to reset on your account that would help with any of this.  Account issues prevent the game or some purchased content from loading, or block Gallery access, that kind of thing.  If you want to reset your user files, move or rename the Sims 4 folder in Documents > Electronic Arts.  Start a new save with no Gallery or library content and see how it runs.

If that doesn't help, this may be a system issue, and in that case I'd like to see a dxdiag.  Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop.  From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.
