Hello, and welcome to the forum!
I'd have a drop down or option button for the user to select to choose which type of equipment they need help with. I'd have separate sections on my form for the questions for each type of help available. I'd condionally hide those secitions based on the dropdown (or option) selection. So if the selection was not equal to laptop, for example, hide the section with the laptop questions.... Make sense? This way, none of the questions will show until an intitial selection for type of help has been made, and only the questions for that selection will show.
