When you say you can access the Google/Yahoo home pages, does clicking around in there / searching actually bring up new pages (eg. search for bleepingcomputer on google, do the search results appear)?
How are you trying to connect this computer (ie. wired or wireless)?
Are you connecting this to a router, or another modem, or...?
And lastly, make sure there are no conflicts with the ethernet card / wireless card in device manager.
