Unknown device after Win 10 fresh reinstall

[Chikara]

Hi,
This weekend I just did a fresh, clean install of Win 10. Everything seems to have gone fine, except for one minor issue.
In device manager, under 'other devices" I have three items with yellow exclamation marks, clicking into them says "The drivers for this device are not installed. There are no compatible drivers for this device. To find a driver for this device click Update Driver".
But clicking update driver, and then search automatically, says Windows could not find drivers.

I haven't tried manually installing drivers as I don't know exactly what drivers I need. There are quite a few optional drivers showing in Windows update but I'm cautious to try any of those.
The three items are:
PCI Memory Controller
PCI Simple Communications Controller
SM Bus Controller

Am I right to think this is MB or RAM related? SHould I try going to the MB Manufacturers site and installing any updates I find there?

So far the PC seems to be performing well, so if this is causing any problems I haven't noticed any yet.

Win 10, 64 bit, and I have not installed any new hardware after doing the reinstall.

likely a chipset driver or similar is missing.
If you right click the device, hit properties, then go to the 'details' tab, you can select 'Hardware ID's' from the dropdown. Copy and paste any of them into google and it'll give you a good idea of what the device is, and you can then grab drivers accordingly.

Yep, that was the problem, I needed to install both the Chipset Management Engine Interface, and the Chipset driver, now those devices are appearing normally in Device Manager. Problem solved
