This is usually more of an issue at the web server; not on your system. It usually happens when a web site undergoes major changes and if you usually navigate the site using old saved links. Try going to the home page of the site and navigating down through it. If you're still running into issues, try contacting the site manager for assistance with a list of broken URLs. If the site manager (or even a friend) can visit the same URLs without getting the 404 errors, then there is, likely, something wrong with your system.

Oh My God!! The site is opening now without any errors(tried 3-4 times no errors now). You're right that it may happen when a web site undergoes major changes. The thing is the site was loading normally on my android phone & not on my laptop during that period... so I waited & searched Google overnight for this but can't find any reliable solution(most of them went above my head). Then at last I asked it here...& after an hour or so those painful errors are gone by their own. But you truly helped me bro as I don't know that even site management may cause this issue which appears to be a local fault in my system. That adds to my experience with windows :-).
One thing I already know that : "As long as we don't mess around with system unknowingly then most of the errors(if any) are resolved automatically". & I tested this fact today:-). Thanks bro!! it was really a pain...& u helped me!!
Thank you very much...!!!:-) :-)
