any browser does not open

Hi, i have windows xp. I hve a connection clear to the internet which is high speed. I cannot get a web browser to load up and connect. I have other computers and all work fine on this line. I have replaced the Cat5 cable. i have downloaded (on my flash drive) (On one of my other computers) IE7 and Firefox. Uploaded to the computer that cannot get a brower to come up and still cannot display page. I tried to rollaback to a date to reinstall...did not work...still the same. What did I uninstall to make this not work suddenly? did i do it? Is there a possible fix...Thank you!

 

"any browser does not open" is somewhat ambiguous since you state a page does not display error.

One is an application issue (the browser simply won't start, regardless of the display output) versus a page display error (the browser starts, but will not display any internet page).

Kindly specify about your issue.
