new Comp to several problems

ok got my new rig today, hooked everything up plugged in all those wires etc etc.
install windows..and now ive got windows live messenger not logging in, to get some things to work i have to restart my pc which i never had to do before.
i cnt log into Steam or the BF2142 demo, does anyone have any idea, the only firewall installed is the windows one and ive allowed all necessary things and ports and still no result, any ideas??
