I spent last week debugging why my machine was dead. The symptom was that it would turn off right away when it's turned on. I suspected the root cause was either the CPU, memory, motherboard, or power supply failing. So I replaced every component with parts from another computer, but it still didn't work.
The root cause was that the power button of the case was broken, causing it to always appear as if it was pressed, so it would turn off every time I turned it on. That was totally unexpected. I just replaced the power line with the reset line and it works fine now.

@hyeyoo some time ago my father in law's computer was misbehaving, loading any website would then make it disappear immediately, navigating Windows Explorer was impossible etc. then he moved another working computer from elsewhere to the same desk and it started doing the same. Was the home router pwned and spreading malware? No, the keyboard's "back" button was stuck...
