Have a look through these common problems and see how many you deal with.
Note: I’m an experienced, self-trained digital ‘helper’, a mentor, as opposed to a computer technician. As such I can rectify many things but not everything, and conversely I’m good at many things technicians are not so good at.

I’m working on some checklists which will allow you to better visualise and communicate the assistance you need.
I’ll add them on this page when they are ready.
