Hi @BrunetteVetTech

Welcome to the HP Support Community. 

What's the operating system installed on the computer and the exact model name of the PC? Click here for steps on finding the information we need. Do not share any of your personal information such as serial, phone number, email ID, etc.

While you respond to that, try these steps -

1) In Windows, search for and open Device Manager.
2) Expand the Human Interface Devices list.
3) Right-click the touch screen device, and then click Enable, if possible. If the Enable option does not display, continue to the next step.

4) Tap the screen to see if it responds. If it does not, continue with these steps.
5) Right-click the touch screen device, and then click Uninstall.

6) Restart the computer to reinstall the touch screen driver.
7) Tap the screen to see if it responds.

If the issue still persists, you may refer to this document for further steps - HP PCs - Troubleshooting Touch Screen Issues
 

Let me know how that goes.
