i do exactly everything and prepared the usb but when i started to boot it i just had the apple logo then my pc went in some kind of sleep mod when press power button again i had just black screen

i tried to boot it through verbose mod and i had this problem (unable to open /var/db/bootcache.playlist : 2 files directory not found )
then i tried ignor cache mod but it's the same after secondes the machine just turn off itself

i tried and tried and tried ...  but no luck
i do not know if the files in that topic work for my pc
can anyone help  me with that ..please i need it
