Computer won't start. Just makes a popping noise.

Hello,
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?

Check and recheck connections... Check for shorts and look for bulging capacitors.

Q: How can I test my power supply?

A: You can easily test a power supply for functionality with a simple paperclip. First, disconnect all the cables from your motherboard and other devices, but leave the power supply plugged into the wall. Next, bend the paperclip until you have a U shape. Find the 24-pin ATX connector and plug one part of the paperclip into the socket where the green wire ends, and the other end into the socket where a black wire ends. Make sure the power switch on the back of the PSU is on, (should be the I symbol) and the fan should spin up. If it doesn’t, your power supply may be bad.

Hmmm how much is that BS meter reading?

It's broke, it's supposed to fluctuate... I think I'm going to RMA. :lol:
