Need more information, first, how are you hooking up to the system? Router, server, etc. Hardwire or wireless? A bit more info may help.
I'm running Windows Vista 64 bit service pack 2 with IE 8 and when i click on IE icon nothing happens i also have Fire fox and Google chrome and when i click them nothing happens but i can click on other icons like control panel and stuff and they open fine its just when i try and open something that has to do with the internet, I tried to load IE 9 on it thinking maybe that would fix it but it wont let me install it.
