There could be any number of reasons really.
1) Javascript is off. Turn it back on.
2) You're using AdBlock, AdBlock Plus, or NoScript. Check to see if a filter in either extension is blocking these forums.
3) A desktop program is blocking these forums. Check your anti-virus, anti-spyware, and firewall programs to see if they aren't silently blocking these forums from loading. If you have parental controls active on your computers, try disabling them or tell them to allow these forums through.
4) One or more parts of these forums are directly hotlinking off sites that are currently down, so that'll keep the forums from loading until the third party items fully load or finally time out.
