I have successfully installed the Mac Sierra and it was working awesome but suddenly one day the mac partition files got missing so i repaired it and the files came back but now while booting, on apple logo it suddenly gets turned off. Here is the picture in verbose mode where if turns off n Nothing happens

Any help would be appreciable
Thanks in advance
