Can't access things I always do!!!help!!!

Hello,

I was wondering if someone could help me.Yesterday my laptop was fine. Then when I went on last night some things didn't work. A few of the problems are that I can't check my email or I can't sign into king.com where I always play games. I put in my password and click log in and it doesn't do anything. Or if I put in the password and push enter it doesn't work. There is a message board that I go to all the time and they have an arrow that you can click on to take you to the top of the page.When I read posts I have to drag the bar back up to the top instead of just clicking on the little arrow thing that automatically goes back to the top. But I can log in to other things like my myspace but it doesn't load everything like friends updates and things like that. Does anyone know what's wrong and how to fix it?? Thanks!!
