Internet Connection Problems?

[whisperingpleasure684]

For some reason when I try to go on certain websites, they won't load up for me. I refresh couple of times and they still don't show up. I don't think it's my service provider, I just want to know if I can fix this on my own. I get this error; (Make sure your Internet connection is active and check whether other applications that rely on the same connection are working.)
