@SoundBoard Welcome to HP Community!

• Did you check if it works fine on the BIOS screen to identify if it's either a hardware or a software issue?
  • If it works fine on the BIOS (Accessed while tapping F10 during a restart) it's a software issue & I suggest creating a new user account to check if that works better, for starters)
  • However, if it doesn't work within the BIOS either, I'm afraid it's a hardware malfunction and you'll need to Contact HP to have it repaired.
• Does the mouse work fine? it doesn't go around randomly clicking things does it? perhaps check with an alternate mouse to rule that out as well?

While you respond to that, I have a few more steps that should help:

Attempt to run a test from the HP hardware diagnostic tool, using this link: https://hp.care/2yTWjBQ (for details).

If the Touch screen isn't appearing on the diagnostics, it could again, determine a hardware failure,

If it works on bios & the hardware tests passed: please update the BIOS & Chip-set drivers from the HP website using this link: https://hp.care/2rbrsPQ;

if the issue persists, reinstall windows using the recovery partition or the recovery media to fix the issue, use this link for details on performing the recovery: https://hp.care/2LwsGNj

Let me know how that pans out

I will have a colleague follow-up on this to ensure it's taken care off, in case you don't respond in the next 24-48hrs,
