Windows Vista Since getting Vista I'm unable to get on some websites

[hoppityes]

Since getting a new computer with Vista I can't get on some websites. I have tried viewing these sites on explorer and firefox.....all I get is a white screen and the page is trying to load but it never happens....had no problems viewing these websites with xp.
How do I get past this problem?

Do you have SP1 installed? If not, use the link found in the support thread and install it. Sp1 contains several updates that originally were released on there own for this very problem.
