Try the following:

1) Go to device manager. Right click the start menu button and click on device manager. 

2) In here, open the human interface devices drop down.

3) Find the one with touch screen on its name.

4) Disable the device (or enable if already disabled) by right clicking it and clicking disable device. 

5) re enable the device by repeating step 4 but clicking enable device. 

6) Right click the device and click on update driver. Opt for automatic update.

Now check to see if the touch screen works.
