Desktop Video, Display and Touch

I purchased my All-In-One PC around 2/2016. About 4 or 5 months ago I noticed the touch screen was not functioning in certain areas of the screen. I changed my password (since I was using a photo, no big deal). I decided to play a game using touch screen, this is when I first began troubleshooting. I have not seen any solutions that seem to work. I have grown extremely agitated with HP since I have read that this issue has been going on for a while and no one has taken the time to correctly identify the problem. NO I do not wish to invest several hours of my time reading hundreds of posts that do not apply to my situation. I have tried to remove the Human Interface Device/HID-compliant touch screen. I have tried update drivers. I have tried to recalibrate my touch screen (and for the record, it does no good to calibrate only the corners)... I have rebooted, unplugged the device from the wall/chord, etc... None of these things has helped me. I was about to update the BIOS, but the instructions did not match my operating system, so that was no good!!! WHAT IS WRONG WITH MY BELOVED COMPUTER AND WHY IS THIS PROBLEM NOT BEING RESOLVED???? I am a die-hard HP consumer! I will only buy HP products, i.e. laptops, printers, desktops, monitors, mouse, keyboards, speakers,cd/dvr device, jump drive,  the list goes on and on with me!! What I do not appreciate is the device not performing and no one from HP helping the thousands of loyal consumers. This is not just my problem... trust me I have been reading post after post of disappointed consumers! When will someone in technical support help us???
