hello. this is my first post so i hope it's in the right place. i've installed several updates to my windows with autoupdater but something happened to my internet connection. whenever i try to open a new page, it doesn't load and gives me a blank page. only my yahoo messenger works, the rest do not load. i tried to deactivate some programs at startup with msconfig but that didn't work. how can i check if something is blocking my connection?
