I upgraded from Windows 8.1 to Windows 10. Windows Update says that it is up-to-date. Windows Devices Manager shows a problem with two devices:

 

PCI Data Acquisition and Signal Processing Controller

SM Bus Controller

 

What are these devices and where do I locate the drivers for them?

    I believe they are both chipset drivers, check to see if there's a driver bundle for the mainboard chipset.

    I installed the Windows 8.1 chipset drivers from Acer, which seem to have worked. No Windows 10 drivers are available at this time.

    That should do it. I've been pleasantly surprised by how well older drivers are working in Windows 10. I had to install Vista 64bit drivers for an ATI video card (the latest working drivers for the card) and they actually worked! Smiley Happy
