You should reload the driver for the "touch screen" segment of its operation or related driver. However, if this is a recent fault, then at least try using a "restore point" to date when the problem didn't exist. If the problem goes away, then some updated driver or corrupted one maybe at fault. You can also use the "repair mode" during the boot-up and see if that helps to correct minor start-up or OS faults. I do exclude any true h/w fault, as the display still relies on touch screen option to work at its basic level. Report back your results for possible further help. Also, provide what model# this is from the product label/decal itself NOT the logo badge.
