Have done a successful clean installation of Windows 7 Ultimate 64-bit on my ASUS notebook computer. It works perfectly.
Windows 7 contains the necessary drivers in itself. You don’t need to install the drivers. After the installation is completed, go to Windows Update to get the latest drivers.
As for the Windows 7 Utilities, such as the ATK_Hotkey, Splendid, Power 4 Gear and so on…, you can download them from the following support site.
Everything works properly. There is no problem at all. I think that you can also install Windows 7 on your X59SL notebook computer successfully.
