When I check the Hardware tab under "MY-PC Properties", I see that SM Bus Controller has no drivers installed, with a little yellow exclamation mark icon next to it.

I went to the ASRock site, and tried to find the appropriate driver:

http://www.asrock.com/mb/Intel/Z77%20Extreme4/?cat=Down...

However, I don't see any SM Bus Controller driver there. I used to also be missing my USB Controller driver, but that one was on the site (ASMedia USB 3.0 driver ver:1.10.1.0), which I did successfully download and install.

Anyone know where I can find the driver for the SM Bus Controller?

It should be in the chip set drivers! Maybe try installing it through device manager!

Could you please elaborate a bit? I'm not too sure what you mean by device manager, but if I click "Update Driver" in "SM Bus Controller Properties", and I search automatically for software, Windows doesn't find anything.

Did you have it search your motherboard disk?

I don't see the option to do that. I can either do an automatic search of my computer and the internet in which I'm given no other options, or I can do a manual search. And I'd imagine that the driver that comes on the motherboard disk isn't the most up-to-date. Is there really nowhere to find it on the internet, even on ASRock's site? If that's actually the case, then I can try to dig out the disk that came with the motherboard...

Try the intel management engine driver or the INF driver above it, but really the drivers on the disk are often the same. Most board makers just call them chip set drivers.
Manually you can go on the disk and it will find it if it is there.

Unfortunately, I just searched my garage and found literally every box for every piece of hardware that I used to build my computer... except for the motherboard box. Very frustrating. Thus, I don't have access to the disk...

Installing INF driver worked for me.

Additional info:

ME driver solved "PCI simple communications controller"

Update driver software in Device management and searching "Driver" folder on motherboard CD solved 2-3 other unknowns (USB30,USBRoot)
