I don't recommend (and neither do the moderators If I recall correctly) the use of driver-locating software like DriverPack etc, especially when your laptop brand has excellent manufacturer's support on the web.
You should download drivers manually direct from the Acer Support website as that's the only way to be sure of what you are downloading & that they are the correct drivers for your model.
Select your Windows version on this page & wait for it to refresh:
