Have you tried booting with Live Linux on a usb flash drive? Is there any component that draws excessive current on + 5V ALW?

Have you tried it with a blank hard drive. If it shuts down while trying to boot windows from the hdd, you may have a VGA chip problem.

Done, thank you, suddenly upon testing the main reg failed, the ldo output are missing so I tried to replace to a new and the shutdown issue solved, thanks a lot
