My Canvas A1 is not starting

My Micromax Canvas A1 is not starting. When I press the power button, it stuck on booting animation. Even I tried to get into recovery mode to perform hard reset but recovery mode is also not opening. My phone stuck on micromax logo and did not proceeded further. My Phone is not rooted and running Android Marshmallow 6.0.1.
Please Help.
