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=Download&os=Win764

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?

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.

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...

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)
