So the latest save game folder appears to have the same files, of about the same sizes, as your other saves? The save folder should contain a Global.lsb file, SaveName.bmp (not essential) and SaveName.lsb, as well as a LevelCache folder containing several lsb files for specific regions (ie CharacterCreation, Cyseal, Homestead).

Was the latest save folder renamed, or marked as read-only or anything like that after the BSOD? If the SaveName folder isn't the same as the SaveName.lsb file in the folder it will not show up in the save.
