You should use the Device Manager to identify which specific devices are installed in your mini before trying to blindly install drivers.
If a device is not installed in your mini , a driver installation attempt will indeed tell you that it can find no supported device. Post the PCI\VEN for each device that has no driver installed in a post here in your thread.
Drivers are located at the web support download portal for your notebook. That does not mean that all of the devices that have drivers are installed in your notebook.
