Problems with my old Arduino

I have an older Arduino (2018) that doesn't work on my new computer while it works on my old laptop. 
When I upload a sketch the pins don't work but it takes it. 
I have tried several programmers but it doesn't seem to matter. 
It is strange that when I upload the blink with the built-in LED it works. 
Can anyone help me?

Which board?

What exactly do you mean by "don't work"?

Please post the sketch.

[pre]It seems the pins are not working at all, I have an Arduino Uno. 
I'm sure it isn't broken because it works on an older version of the Arduino IDE.
