GTX285 always running at full load?

Before this, everything works fine. My card auto goes into 2D mode when idle and into 3D performance when I playing games. After installed some basic program and Vista update. When boot into Vista, the clock speed is always running at 648MHZ even idle. I try to restart comp and still the same and you can't DC or OC it. The only thing you can control is the fan speed. I am running on Vista Ultimate X64 and using the latest driver from Nvidia. Please help and sorry for my ENG. Thanks.
