BearyBry Please test with no mods or custom content, as in, move the Mods folder to your desktop and delete localthumbcache.package. Even if you'd never play like this, it's important to find out whether this is the source of the problem.
If you get another freeze with no mods or cc present, please provide a dxdiag. Hit 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.
