Help: hwmonitor doesn't show anything

Sorry for my complete noobness, but that's my first build
I installed hwmonitor but it shows only the cpu and doesn't show any voltages, or temps , neither the other components.
Going on the bios everything is showed (temps, fan speed, ...)
Do i need to install some driver or something else first to show those stats in win 7 ?
Thanks
