I was using my computer and it started having phantom touches all along the vertical middle of the screen. I contacted HP support and i was told to upgrade my bios but can't find the file.

@ArsalSherKhan Welcome to HP Forums Community!
All devices do not have BIOS updates available for download as its subject to updates released by the specific product by the manufacturer of the motherboard of your device, also, the issue you've mentioned may not be resolved by a BIOS update, here's what I suggest instead:
I recommend checking if the Touch is working on the BIOS screen (Accessed by tapping on F10 while restarting the computer).
If it works on bios, it's a software issue: please remove/uninstall the touchscreen drivers from the device manager and restart the device, if the issue persists, you could reinstall the windows using the recovery partition or the recovery media to fix the issue, however, if the issue persists after restarting the device as well, 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 fail, please capture the 24 character failure ID and revert with the details. and if it passes, we may need to check if a windows program is conflicting with the touchscreen, try checking if it works in safe mode.
Let me know how that pans out,

Hello, in order for me to help you I will need a little bit of information such as what the exact model number of your computer is, you can find it on the bottom, or back of the computer, or sometimes by pressing fn+esc when on the desktop of the computer! Have a nice day! 😁
