Windows ME problem restoring

For some unknown reason I started getting a error message when I booted up my computer, that said it could not find boot devise or something like that. I finally was able to get it to a point where I could restore the Windows ME and some other applications. When I ran a Scandisk it came back on my hard drive with some bad sectors. How can I fix that or is there some utility I can run on my computer that will give me a list of problems and how to fix them? I can not seem to get my printer to work now or connect to the Internet.
