ati smbus不正常工作怎么办？

I just wanted to relay this bit of information: I had a similar issue where the ATI SM Bus showed no drivers installed (yellow exclamation point.) Any attempt to update the drivers resulted in "Access Denied." In spite of being logged in with an admin equivalent ID, I was not able to install the correct drivers. I was able to install the drivers by re-running the setup.exe using "run as" and choosing the actual Administrator ID.

Assuming you're using an ATI video card, the default location is C:\ATI\SUPPORT\8-4_xp64_dd_ccc_enu_61003\SBDrv\Setup.exe

Otherwise try using "run as" Administrator with the setup program for south bridge driver for your motherboard.

Hope that helps some folks!
