the minecraft does not open

The minecraft does not open to me, only the launcher opens, then I give it to play and the MOJANG window comes out and it remains frozen saying (minecraft does not respond). The minecraf worked well for me when I bought it, but two days later this problem appeared when I was installing a texture pack. Install that pack and when the minecraf opened, this problem appeared. I removed the minecraf and reinstalled it but this problem continues to arise. please help me I have spent money to play this game, I am very upset to have bought this game and not be able to play it.
I use a laptop with windows 10
