i don't know the real history

question folder at boot

if i try to boot any os from usb, it goes to internet recovery

i've restored in dfu (lock symbol on apple configurator)

booted in internet recovery

as soon as i try to go to Security Utility Boot , it says me that there is no administrator.... and after some second, fans goes at max speed and reboots.

i don't know....could it be an ssd problem...i'm pretty sure that there is an hardware problem....

just because fans at max speed, just because sometimes it hangs completely when i'm choosing which os boot from usb...

No errors…

I’m pretty sure that I have an hardware problem but where to start?

For example now I have a bicolor loading bar… and it is loading since 50 minutes…

no...it's seems to work without problem...previous technician sent me a video of the macbook booting: APPLE LOGO + BAR, then black screen, then apple without bar, then point arrow big and loading bar big, then reboot.

in another video, it boots to desktop, after 2 minutes, fans a top speed and then reboot.

i have never had those problems after reaching to format and reinstall the system
