IE pages not responding

I have been having to use the Task Manager to shut down Internet Explorer due
to the pages freezing up. When I open task manger it indicates that the page
is not responding. This happened approximately 30 times today alone. I have
no idea what is causing this problem so I don't have a clue as to what to do
to fix it. I finely got so frustrated I just gave up and shut my system down.
I'm running the VISTA operating system and, as stated above, I'm using
Internet Explorer for my browser. I don't know what other information you may
need to try to help me figure out what may be causing this problem. I'll be
happy to supply whatever info you may need.
I'd appreciate any help I can get. Thanks
