A great price for a great computer. First, install all updates for Windows 8.0, and only then it is possible to install the update to Windows 8.1 Be patient, it takes several hours and even if you do not see progress, wait. After the update 8.1, a problem with the touchpad does not work, reinstall the driver / driver and now it's working. (For the touchpad driver, go directly to the Asus site)
