I have tried disconnecting hardware to isolate the problem. I can't read anything onscreen except I can see what appears to be a GUI interface. However, the computer abruptly shuts down immediately after the GUI appears. I have tried booting to Apple's hardware test DVD. I have also tried network recovery for High Sierra but the result is the same. The High Sierra installer stalls after passing the halfway point. Booting from the Leopard installer results in a kernel panic after booting for ~3 seconds. My flash drive has bootable installers for Leopard, Snow Leopard, Lion, and High Sierra. I am able to access single user mode (Command+S).ДЄfter this failed, I attempted booting from my reliable flash drive. I force shutdown the computer each time is freezes. The last message was 'previous shutdown cause 3' for force shutdown. It simply stops logging messages after the computer freezes. I attempted verbose boot mode and there is nothing unusual. I attempted booting and it would stall while loading the OS. I first attempted booting from a 500GB HDD preloaded with Lion, which has since been allocated for something else. However, the computer is completely unresponsive.

USB devices have power for a few moments after freezing and then power is cut.
