Unfortunately, I don't know how to do this, and probably don't have the equipment for it.
You should have a choice to either take a screenshot of your entire screen or only a portion.
To protect your privacy, I would suggest only taking a screenshot of the problem area.
If you're satisfied with the screenshot, save it first, then upload it to a photo hosting site.
Then share it here on FR.
If you want to.
If you don't know how to take a screenshot and you "don't have the equipment for it", how are you going to follow any instructions on how to fix the problem?
This requires some work on your part.
