my game crashes and my sims are acting like they are in a snow storm inside

quueen​  For the crashing, please provide 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.

For the other part, what exactly do you mean?  Please describe what you see in more detail.
