Internet Explorer freezing (Not Responding)

I have a Dell Inspiron 15 Laptop. It has worked great for about 1 1/2 years, no big issues. All of a sudden today, when I start IE, it takes longer to come up, then is pretty much useless. I see my home page, but can not click anything, enter web addresses, or even access favorites. When I try these, or even try to X out of the page, everything freezes and I get the (Not Responding) after the name of the website at the very top of the screen. The rest of the computer seems fine, programs, pictures, etc...I ran 2 different virus scans, no bad results. I've had this happen a couple times in the past and I've restarted and all is good. This time, nothing seems to work.
