I think either you have messed with your website, or some internal error is causing so many pages to give 404 errors. If you are using Wordpress, then you can install plugins like Yoast that automatically generate a redirect for 404 errors.

404 pages are REALLY annoying. I recommend you find a good freelancer for $3 an hour to get the issues fixed.
