Constant beach ball spinning with Safari

I'm posting this for a friend. She is running OS X 10.4.11 and Safari 3.0.4. Starting a few days ago whenever she opens Safari she just gets a constant spinning beach ball and no web page will load. She tried clearing the cache and verifying and repairing permissions but that has not worked to resolve the problem. She said she has done all of her software updates as well.

Does anyone have any suggestions for her that might solve this issue? Thanks in advance for your help.
