    Popping sound comes while switching off PC

    Hi, I have recently bought a machine from one of my colleague but I am having very strange problem with the machine as whenever I start my PC, it just start causing annoying popping sound from the cabinet. And that I was not having previously but don’t know what could be the problem and from last two days I am having this kind of noise from the machine.

    The popping sound carry on with a concise wait between each. it also reduce in volume as does the intensity of the power light. The repeatedly retreating popping sounds and light persist for about 15-seconds. I have observed completely no other odd behavior by my PC, including any other strange noises.

    Any idea what could be the problem?

    As the extent to I know once the fans stop operating, the computer formulate a popping sound which is heard through the speakers. Thus according to me there is surely some problem with the Fan that you are using in your cabinet, make sure whether it is working perfectly or not, and as you got any problem with it you can have option to change it. but before that should perfectly test it for sure.

    Are you getting just the popping noise or along with that any clicking noise as well?

    Because once I was also having the same problem but together with clicking noise and later I came to know that there were some problem with the hard drive that I was using in my machine.

    According to me this irritation is not just your PC.

    But I've seen and heard this on dozens of PC’s and unhappily I would say it's not a imperfection but a mark of deprived design of the audio system on that motherboard.

    I have resolved it permanently in the precedent and would suggest you the same thing do as you should try to disable the on board sound and by means of other sound cards you have to configure the sound settings. and then see what happens.

    See according to me there could be so many problem that causes such popping sound while starting the machine and such a threats are either Speakers, Speakers malfunction, monitor, monitor malfunction and lastly some other Additional Concerns.

    Though several popping noise throughout boot up are usual, others are not. some popping sound escorted by a flicker, current of burn or unexpected power defeat point to a more hazardous trouble that could curse the end of your computer or pretense a fire threat. While in hesitation, power down your computer and cautiously ensure the inside of your case for signs of short circuits, threadbare wires or scorch marks.

    I am agree with the above user as you should try to make some changes through configuring the settings but if suppose if you are still having the same problem then according to me you should hire a good computer engineer and then carry out solution for this, but until that it would be better if you don’t run the machine in such a condition as this may lead to damage any hardware as well.
