My dell 5565 laptop touch screen has suddenly stopped responding and just recently my usb ports have as well. When I restart the usb ports respond then become unresponsive in a few moments. I ran a diagonstic test for the touch screen and I was able to use it when I pressed f12 but when I log in it doesn't work. I've also noticed I seem to be missing a few contents in Human interface devices and touch screen is missing from the options.
