I did a fresh install on this generic pc which was made at a computer show, Vista Home Premium installed fine but when I try to run windows update it shows "windows could not search for new updates", that's the first problem. I then tried to update from IE7 to IE8 but it doesn't work. I also can't install either FF or Chrome, then Adobe flash player won't install to watch youtube videos but I can go on any website with the IE7, ay ideas please?
