Select non-empty cell range with VBA

Hello,

First of all i want to thank the people that helped me with my previous question.

I would like to ask for help with the following issue - i have three columns that look like this:
1.png
Which should have a selection around them like this:
2.png

The macro should ignore rows that do not contain values in all of the three columns.

Unfortunately i do not know VBA, i have searched for this issue on Google and found some information but i cannot put them together.
For exemple:

Thank you for your time.
Daniel.
