Ascend Plus (H881C) reboot loop

I was using this phone for a while, and one night while on the XBOX app it just froze and rebooted its self. Now it will only turn on then reboot then turn off. I have tried to hold the power button and the volume up button, but nothing shows up. the screen just stays black. Any help would be greatly appreciated. Need to do a factory reset of some sort to wipe it clean and start from fresh. thanks again.
