i've posted about this before but it's still not fixed so i'm doing it again. basically my dell laptop refuses to load up certain sites like gmail and facebook and comes up with a 'page cannot be displayed' message. for everything else it works fine.

it doesn't make a difference in ie or firefox and it won't let me download java for some reason. i've checked the security setttings and all that business but nothing.

does anyone know what the hell is wrong? it's sooooo annoying!!
