My guess is that something downloaded to your computer the wrong driver.
The Asus UX32VD is relatively new I think. In fact you will know of course, but it could indeed be only a few months old
Have you installed any program that will monitor and automatically update your drivers - they do unfortunately have a habit of choosing the wrong one sometime.
My advice is to obtain drivers ONLY from the Asus site, especially whilst it is still fully supported OR from the manufacturers site of the component - later when Asus have stopped supporting it
There are two places to go firstly the Touch pad driver you have seen, on the image you sent is the Elan Tech touchpad driver
http://support.asus......&hashedid=n/aHOWEVER I am not certain it is the right one as the Asus site for your laptop tends to suggest it is not the Elan tech driven touchpad
http://www.asus.com/...X32VD/#downloadENSURE you configure that for your operating system please. AND indeed if you know that your model does have the ELAN, then the same on there.
I do not know where you are located and there are of course slight differences in models sold in different parts of the world.
NOW how to proceed in the first instance
Go start - windows button and programs, accessories, system tools, sytem restore - when that opens , click next (usually) and the restore point offered MUST of course be before the problem eg not yesterday
If necessary click the box show other restore points
Follow the procedure to restore and you should be back to all working.
NOTE anything installed, docs, images etc changed since that restore point will be lost so ensure you have anything necessary backed up and copied.
Then of course providing all works, you will have to ensure that you do NOT accept the update for the driver - if indeed that is what has caused this.
