Why does my nextbook 8 keep restarting?

It keeps resetting every once in a while, about every 7-10 minutes.... And my My Singing Monsters won't work saying that there is no internet connection when there clearly is....

Every once in a while it will just go black and say Nextbook TM and the word will have a little light flash by it, that whole thing would go on for about 35-60 seconds, then bring me to my lock screen, then once i do the password, my tablet would be good for about 7-0 minutes before it restarts again.... Please help me, i just got this tablet on like, 11/16/16, the day of shop with a cop in covington.... and ny asus memo pad 7 stopped turning on at like, 9/??/15 or something, i got it the day after easter lat year in 2015, and i don't think my mom is gonna get me any more tablets after m new one goes out.... so please, Please, Please, PLEEEEEEEEEEEEEEEEAAAAAAAAAAAAAAAAAAASSSSSSSSSEEEE!!!!!!!!! HELP ME!!!!!!!!! Please help my with this problem. please.... ( =^ (
