I would suggest you to try uninstalling and reinstalling the touch screen drivers in device manager and check if this helps.
a. Click Start, and then click Control Panel. b. Click System and Maintenance, click System, and then click Device Manager.
Note If Control Panel is in Classic View, double-click System, and then click Device Manager. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
c. In Device Manager, expand the appropriate category for the touch screen driver and right-click the listed driver. Here you will get all the option to update or Install/uninstall drivers. Click on Uninstall. Check if at all there is an exclamation mark along the driver, it suggests issues with the driver installed. d. Restart the computer. This will let the computer automatically detect the device drivers on restart of the computer. Now check if the issue resolves. If the issue persists you may contact or refer to the website of the computer manufacturer and get the latest drivers installed for the touch screen to work properly.
I saw some other threads, and people were able to find drivers that would work with windows 8 that would allow the touch functionality. Since others got it to work, I thought they could be a possibility that I could also get it working.
I have just gone threw this problem i had win 7 and every thing was fine i upgraded to win 8 then win 8.1 and lost my touch screen i could not find any driver out there but then i unplugged my acer wireless keyboard and mouse usb reciever in the middle os a restart and when it booted to win 8.1 my touch screen was working so i then started plugging in dirent mice and keyboards i ended up with a usb logitec keyboard and a logitec ait wireless mouse and my touch screen is still working well i am not and engineer so i donot udersatnd why but it work some of the keyboards i tried where microsoft wireless and a maplin wireless mouse and keyboard i have allso tried swapping them all around but lost touchscreen so went back to my logitec stuff and its fine
Touch Drivers should be included in the CHIPSET, some Touch drivers are included in the HDD Drivers, (Dell on several only if you installed the DELL HDD Drivers, would the Touch work, you could then update to M$ drivers or Manufacture drivers and touch still worked.) also it is possible that any other driver could interfere, i have seen Mouse - keyboard or other drivers jam up touch, had a DELL (client) that if i uninstalled it IRS driver then touch worked. it might alos be the sequence of what is installed first, (some 3d party) programs will allow you to move/set what is loaded first. also you might try safe mode, see if touch works, you can also use log ea to see where the problem (possiblely) you can also check event viewer, for issues...
