I bought a Dell All-in-one 2020 from Craig's List.  I know...but I did it.  So the guy had no disks with it.  He did a fresh install of Windows 7 Pro.  I got some of the drivers that were missing from the web, but cannot come up with the chipset driver from Intel for the SM Bus.  The other problem I have is Dell does not recognize the service tag number or the express code printed on the back of the computer, so I can't get any help from Dell.

Any ideas?

Thanks
