Lilbjudyy If you have any mods or custom content at all, please move the Mods folder to the desktop and try again. You don't need to save your progress in any of your main saves, or you can use "save as" and rename the save so you don't overwrite the original.
If that doesn't help, or you have no mods or cc at all, 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.
