Why is the phone in the boot cycle?

When turned on it just keeps loading the phone logo over and over. When you try the factory set, it shows normal but when you press the power button, it loads the logo over and over. How can I resolve this issue?

Do you have any microSD card? Remove it. Then factory reset it. (just google - Press Power + volume UP). Hold down the Volume Up for a while when an Android Logo appears on the screen. While still holding the Volume Up button, press and release the Power button.
