A yellow exclamation mark appears before PCI Simple Communications ControllerA yellow exclamation mark appears before PCI Simple Communications Controller. Driver ID PCI VEN_8086 Lenovo Inc. Dec 13, 2007 - PCI Serial Port and PCI Simple Communications Controller. The boxes do not have modems. Have looked through Lenovo's site with no luck.
So I did the win. 10 update and chose not to keep any personal settings/files and it feels like a fresh upgrade.
Went ahead and uninstalled the video driver and downloaded the newest one from the Nvidia site.
I noticed I have two unknown drivers in the device manager. I've searched this forum already, but didn't find anything.
The two drivers missing are:
PCI simple communication controller,
SM bus controller.
Any idea where I can find these as I've already installed all the available drivers for Win 10 on the ASUS Site.

- Kloxo has not restarted the web server yet after you added the domain. Please wait for the web server to restart.
- The domain is pointing to the wrong Kloxo server. Ping the domain and make sure that the IP matches one of the IPaddress seen in admin home -> ipaddresses
- If you are seeing this page when you try to access an IP like http://192.168.1.1, then that means that the IP has not yet been mapped to a domain. Go to client home -> ipaddresses -> ipaddress home -> domain config and map an IP to a domain.
- Once you map an IP to a domain, then you have to make sure that the domain pings back to the same IP. Otherwise, if you try to access the domain, you will get this page. So IP -> domain.com should mean that domain.com pings to the same IP.
