Connects to internet, wont browse

Hello,

I have had my laptop not even a year now and it has been working great, however the past few days it quit opening to the internet. I tried different wireless networks and it still will not open. When I try and open it all I get is Internet Explorer cannot display the webpage, then there is a Diagnose Connections Problem i click it and it keeps telling me there is no problem with the connection. What can I do? Is there a reset I can do? I have tried to diconnect and reconnect and restart the computer.
