Try downloading the free program 'DriverMax' @ http://www.drivermax.com/
Register for free. I use it all the time with my Rampage Extreme and it works very well. You will get the latest driver with this.
Hope this helps
Thanks for your help.
I try the system DriverMax in another computer not need a special driver.
But I not like the scan procedure about DriverMax.
So where I can just download this driver:
Intel(R) ICH9R LPC Interface Controller – 2916
