Missing Drivers (?)

I have an Acer Aspire One D257 and it appears to be missing three drivers that I cannot find anywhere on the internet. When I click on "Update Driver" in the device manager no drivers are found either. I've downloaded every driver listed on the Acer website and still no luck. I'd prefer not to pay for a registration to a website that claims it can update all drivers "at the click of a button."

The missing drivers are as follows:

                                    Ethernet Controller (Location: PCI bus 1 device 0, function 0)
                                    PCI Device (Location: PCI bus 3, device 0, function 0)
                                    Video Controller (Location: PCI bus 0, device 2, function 1)

All devices state that "The Drivers for this device are not installed. (Code 28)

Any help will be greatly appreciated.

did you go through this site and put in your model?

As stated above you would go directly to the website and type in you Serial number or search by your product model


All the drivers get listed at the bottom of the page once the model is correct.
Always begin by installing the chipset drivers, then reboot. After that install the other drivers. For most of the other drivers to work and install properly, you need working chipset drivers.

if you have  unknown devices in device manager, you can use this procedure to identify them :

1-visit the motherboard manufacturers support site, for downloading drivers
2- use windows update >optional updates to find them

3-Start>Programs>Accessories>System Tools>System Information.
Now select  "Components" and highlight "Problem Devices".
All hardware devices with a driver problem will be listed here.
Make a note of the first line of the PNP Device ID line of the entry. It will show a Vendor number and a Device number (VENxxxxDEVxxxx) both four digits long.
Look up those numbers here:   http://www.pcidatabase.com/index.php

This will tell you the manufacturer and the chip number.  
Check the manufacturer's website first or google them - or post them here

If your LAN is running, you can also use windows update> optional drivers, or  use slimdrivers : https://www.slimwareutilities.com/slimdrivers.php
