404 Not Found Error

[Joe]

I recently experienced problems with using search
engine. The problem is, when I try to search for
something this "404 Not Found Errors." Also there are
certain sites I cant access like Google.com. It tells
me "There is no website configured at this address." Any
help is appreciated. Thank You.
