HELP! Drivers needed! ASUS G752VL - GC409T

NOTE: I know this should have been posted in the software section, but it's related to hardware.
So... I FINALLY managed to install windows 7 64 bit on my laptop
Now. I've downloaded some drivers from this site: http://asusdriverdownload.com/asus-g...iver-download/ Which I guess is genuine. The problem is that some of the drivers won't install (touchpad, sound), there is a rather loud crackling from the speakers (which is a consequence of the missing drivers, because the speakers don't do that on my preinstalled Windows 10) and also the aero theme doesn't work for some reason. I need an experienced user to send me:
1. A link to the drivers for Windows 7 (I've found only incompatible windows 10 ones).
or:
2. An advice on what should I do?

BTW: Windows seemed laggy after I installed the chipset driver for some weird reason.
