Hey!Just bought my new Asus G750JM Free Dos.I installed Windows 7 Ultimate and it's bought retail.I tried connecting to the internet but it just doesn't want.Some other options didn't work as well.I looked in the Device Manager and the Ethernet Controller,3D Controller,Wireless Controller(i'm not sure about this one),Network Controller,SM bus controller and some others were marked with an exclamation mark.When I cliked them,it said there were no drivers installed.I have an internet stick and I plugged it in and tried to download them using the internet seatching option,and it said there WERE NO DRIVERS.I looked on Asus' website on support for my laptop and there were no drivers for Win7,but were for Win8.1 Look here: http://www.asus.com/Notebooks_Ultrabooks/ASUS_ROG_G750JM/HelpDesk_Download/

And that's it.I don't know what to do.Can you give me some support?Do I really have to install WIndows 8.1 ?
