Every single person you come across will have a different level of expertise when it comes to using computers, some pick it up rather well, others have issues with the basic tasks; it’s just a fact of life you learn to live with working in a service desk environment.
My view and work ethic on the matter is it’s my job to help out a staff member with any IT problem they come to me with. Yes this includes issues outside my work scope, but if I can solve their problem, it usually results in a shower of eternal gratefulness lol. And if I’m unable to help I will at the very least point them in the right direction
My second job is keeping out of office politics which saturate every work place. Focusing on my work and helping people as much as possible has worked very well for me in the past couple of years.
