My computer won't start up and just makes a popping sound. The lights flash on and off rapidly with the popping noise. Like the power is going on and off rapidly. Would this be a power supply problem or could something else cause this?
First of all. DO NOT Start the machine again. Remove the power supply and get a new one. As above poster said hopefully your other components are fine. Replace the power supply immediate with a brand name like Corsair, Antec, Seasonic
