        msg.setWindowTitle("Lame")
        msg.setText("your computer is Lame. Thank you")
        msg.setIcon(QMessageBox.Warning)
        msg.standardButtons(QMessageBox.Ok|QMessageBox.Abort|QMessageBox.Ignore)
       x = msg.exec_()
        
if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

I guess you need to use msg.show().
