Open the Device Manager on your laptop. (Start > Settings > Control Panel > System > Hardware > Device Manager). Work your way through all of the components, taking particular care to look for anything with yellow exclamation marks, to find out what you're actually seeking drivers for.
Then try to find the drivers you need on the Asus website:
https://www.asus.com/uk/support/
(If you can't find them there, try the websites of the relevant device manufacturers). Download the driver installation files, via your PC, onto a USB stick. Copy them onto your laptop. (The location where you put them is unimportant. The desktop is as good as anywhere because you can delete them after running them). Then double-click on them to install the drivers.
