Question for Pinterest Addicts

A few months ago Dianne from Collages and Creative Goodness turned me on to Pinterest. I did not join, but I go there almost every morning to be inspired.  I have been thinking of starting my own page, BUT this is what stops me:

See the "Pinterest.com is not responding" message under the arrow?  I get that everytime I go to Pinterest.  Why?  My computer is not that old...it's fast............???

Is there something I need to do to stop these freezes?  They are very annoying.

Any help you can give would be greatly appreciated.
