A browser problem

First, i apologize if this has been answered, but I did do a search. I have
a Vista Home Premium box and at least twice a day I have to restart because
my web browser stops working. Let me explain, I will try to go to a site,
any site, and I get the message that appears when the PC's connection is
dead. The thing is, is my connection is fine. Other network services are
working just fine. I can still use bit torrent, outlook, itunes to download
music, whatever, it is just the browser that doesn't work.

I use multiple browsers for work and none of them, Explorer, Firefox, or
Opera, will connect to a page. Can anyone help me?
