Have a 820-3023A that wont load osx with built in drive or known good usb drive. After about a minute loading with apple logo it will just turn itself off. Put fresh thermal paste on cpu but made no difference

Have no idea where to start for issue like this.

I have TL86A programmer but do not have a adapter for this type of bios chip. What do i need to get in order to reprogram this type of bios?
