Mouse via the touchpad and Windows 8.1 ... The horror!

I received this Asus WINDOWS 8.1 and already from the first second of starting, ie when starting the installation, it does not recognize the touch pad (touchpad) so no mouse! I installed it using the keyboard like in the good old days of MS-Dos. The finished installation, I connected a real mouse to be able to work ... For a laptop, it is the height. After researching attempts hours a compatible driver, still nothing. Many users complain about Asus WIN 8.1 and encounter the same problem. What then do I have installed many PC and laptop? Rewrite the pilot (driver) of the touchpad to finally own a real laptop? Too many hours spent in resolving therefore the product does not conform to normal use will êtrer returned from Amazon. If you have a solution, I'm interested :-). Thank you.
PS: one of the block activation of oblivion through fn + F9 would have been too simple.
