Android Studio 2.1.2 - Pesado, lento e não funciona. | Android I: Crie sua App fantástica com Android Studio

Olha não sei o que está acontecendo, sempre que tento fazer build acontece e o erro abaixo e trava (fica aumentando o tem em 10, 20 até 30 minutes ago), fora que essa IDE é muito pesada e lenta, não funciona direito, sendo que o meu note é um i5, 1tb, 8GB de RAM.
Erro
