I had this issue with my VivoBook S400CA touch screen and fixed it today doing the following:
  1. Go to the Control Panel.
  2. Go to Troubleshooting (you may have to search for it)
  3. Click Hardware and Sound
  4. In the Device section, click Hardware and Devices
  5. Have the wizard scan your computer for hardware issues.
  6. Let the computer fix whatever issues you had.
In my case there were 2 USB input devices that were disabled that the wizard enabled for me.  The touchscreen immediately started working.  Hope this helps someone.

The problem used to come back periodically.  But since updating all of my drivers a while back, the problem has not resurfaced.
