I changed my RAM and hard disk for my dell inspiron 640m.I installed windows vista home premium and upgrade to windows vista home premium with service pack 1.when i connet my computer to my router via wireless,it says it can access local and internet.when i started the internet explorer,it took such a long time to load google webpage and sometimes it will not load.I changed my connection to LAN and the result is still the same.Anybody knows what is the ploblem?
