L1ZZ1BETH Does the game crash in a new save too? Please test if you haven't already, for comparison's sake. And if you use any mods or custom content at all, test your existing saves with your Mods folder removed. You don't need to save your progress.
If the new save is affected too, 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.
