I have a alienware x51 and I've got the yellow exclamation point next to "SM Bus Controller" in my device manager.  I downloaded the chipset driver and installed it but the exclamation is still there.  Do I need a different driver?  ANY help would be much appreciated!

hi driver was fine until i updated to windows 8.1 from 8. now if i try reinstall chipset drivers it still doesnt fint driver for it . is there any other way to fix. thanks

Is this a x51 R1 or R2 ?

hi its x51 r2

when it was working it was

intel 8 series c220 series smbus controller 8c22

pci/ven_8086&dev_8c22&subsys_05d71028&rev_04\3&11583659&0&fb

thanks again

I had the same problem with JAMESBAILEY and managed to resolve using steps below:

1) In Win 8.1 Device Manager - Remove SM Bus Controller

2) Goto Intel® Chipset Device Software (INF Update Utility) - Install the SetupChipSet...

Step (2), give it sometime to work on it,..

When done, you will see a new SM Bus Controller under Device Manager - System devices
