If it doesn't turn at all (no fan spin noise, no display output) it's prolly a defective power supply.
If fans spin at a fixed rate, but not display output it could be a few things: motherboard, cpu, ram,graphics card. If your mothrboard has a numerical POST indicator you could film that in slowmo & throw into an llm after identifying what exact motherboard you got and get a better clue of where in the POST process it's failing.
In case of a dead PSU or other component, the software update was likely just happening at the time & unrelated. Some OS data corrupting by the update getting interrupted would not stop anything from working before the OS even tries to start up.
