In Word go into tools and options you need to see if there is default autosave location. Then browse to that to see if there is anything there (make sure you can view hidden folders and files (open my computer, tools > folder options > view > hidden files and folders > show hidden files and folders > apply)). You could also try searching your hard drive and USB drive for .asd files (auto-save document) you want to include hidden files and folders in the search.
