hey boys......the problem was, as scutters said, that windows media player was not installed.
It is incredible.
I don't know what happens when it didn't open before the hardware changes.
The people who installed me windows 10 didn't install windows media player, as I fount out that now it doesn,t come with windows and you have to add this feature.
What a silly problem I had and I couldn't see.....
Thanks everybody for your answers, for your help, and of course, for your time......
