Answer 1

A 404 error occurs when a page can't be accessed through a server. You can't remove them.
I see u added info since I answered.
Try clicking, tools, manage add ons, then see if you can spot an add on that looks suspicious. If u find one disable it.
Also try clearing your cookies and history and temp files.
To do this right click Internet explorer, click properties,then delete cookies, files(off line too) and history.

Answer 2

You get 404 errors when you try to reach Web pages that don't exist. Check the link to make sure it's good.

For example, you won't get a 404 error if you go to http://www.google.com
because it exists.

You will get a 404 error if you go to
http://www.google.com/yahoo-answers-is-great.html
because it doesn't exist.

issues like that are often left deep interior the registry and in case you have had the computer over 6mouths you cant reset it as you lose extremely some settings for courses so sorry mate yet your purely real determination is to reinstall homestead windows.
