So...i was near my computer (not using it) when all of a sudden I see it turns off out of nowhere. After a couple of seconds I smell some burnin/smoky kinda thing...so I disconnected it. Then i connected it again..press the button and nothing happens.
Didn't look inside yet.
My question: is it the power supply or the motherboard?? and how can i test it to be sure 100% before I move on and replace either one.
