Whenever I click on IE, it comes up Page Not Found. This happens after I turn on the PC for the first time as well as after I've been away from the computer for a while and try to open a new browser. If I keep clicking repeatedly on the Refresh button, it eventually hits my homepage. This happens on my PC directly connected to my router (FIOS, fiber optic). But...this does not happen to the connection on my MAC which is connected wirelessly to the same router. Anyone have any idea???
