Missing drivers for ethernet controller, SM bus, etc.

I recently built a new pc and noticed three hardware devices have yellow exclamation points next to them. The message said the devices are missing drivers. The following devices are listed:

Ethernet Controller
PCI Simple Communications Controller
SM Bus Controller

I'm not sure how to fix this. I went to ASUS and downloaded the newest update for my wireless card (PCE-AC68), but it didn't fix anything. I'm not too computer savvy, so I might be completely off regarding the problem. Any help to fix this would be appreciated. I did just update my mobo chipset driver which seemed to fix the SM Bus problem, but I'm still unsure about the other two items. Perhaps they have nothing to do with wireless networking? Since I had been having problems with connecting to the internet, I assumed it was all connected.

I also reinstalled the Intel Lan Driver which seemed to fix the ethernet controller. Last problem to trouble shoot os the PCI Simple Communications Controller. Let me know if this doesn't belong in this forum as I'm starting to think it has nothing to do with my wireless card.
