My touch screen computer is going crazy. Ghost touch

[JuanitaLaBonita]

I have had my laptop for about a year and a half and recently the touch screen system is acting up. It would have glitches and it more like a ghost is constantly touching the screen. I would have to touch the screen multiple times for the shaking and tapping of new tabs to stop. Is this fixable?

@JuanitaLaBonita Welcome to HP Community!

I understand that the touchscreen is not working properly.

Do not worry. I will try to help you out.

Just to clarify, did you check if the issue persists in BIOS? if not I recommend checking if the Touch is working on BIOS screen (Accessed by tapping on F10 while restarting the computer) or if you have issues with the keyboard or unable to reach the BIOS: 

I recommend running a hardware test on the touchscreen to be sure since it isn't working in the BIOS, please use the below steps to perform the test: 

Hold the power button for at least five seconds to turn off the computer. 

Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key. 

On the main menu, click Component Tests. 

The Component Tests menu displays. 

Touch Screen Test - Quick interactive test to determine if the touch screen is functioning correctly. (This test is currently not available in the Windows version of the hardware diagnostics.) 
To run the test, click Touch Screen, and then click Run once. 

If the test fails, please capture the 24 character failure ID and revert with the details.  

If it works on bios and the above tests pass, try checking if it works in safe mode. 

Also, reinstall the display drivers, install the latest updates for the display adapters and BIOS,  

if the issue persists,  you could reinstall the windows using the recovery partition or the recovery media to fix the issue. 

let me know how that pans out,

And the answer to the above question will help me, help you!

Keep me posted, and if any of the above questionnaires helped resolve the issue,
