Touch Screen Not Working

I have a 4 year old Ideapad S400, running Windows 8.  The touch screen is "intermittent."  If it's stopped working, I run a diagnostic from the Control Panel  "Troble Shooting" for Hardware & Devices.  I get a message which says:  "Hardware changes might not have been detected" with a yellow triangle with an exclamation point in it. I did not make any hardware changes.   When I re-boot, the problem goes away for a while and the touc screen works.


I am a VERY "low tech" guy - can anyone help with this?  Thank you very much.
