Internet help

Using a PC. I'm no slouch but this problem has me baffled. If a type in a URL in IE the site won't load. My homepage is google, but say I google a site and click the link through there it'll load the page. I just can't type in the URL to get there. All other devices and computers (including a macbook) in my house have no problems with connectivity. It's definitely isolated to my laptop. I use it sparingly, so there's no other browsers on it that I can use to test on.

Any ideas?
