Computer making a buzzing noise

[MarTorb]

Hello, my computer is making a buzzing noise and it's quite load as well. At first I thought it was the power supply, because when the computer was turned off the noise was still there, it only stopped when I turned the power supply off. However I bought a new power supply, but the noise was still there, I think it was not as loud know. The buzzing noise is not all the time, quite rarely to be honest, however is annoying when it does it. Any thought on what I can do?

Sounds stupid, but if you have HDDs in those tool-less caddies, give 'em a jiggle.

 

If that doesn't do the trick, first things that come to mind are loose expansion brackets and fans being bitchy.

The two most common things to produce whats called coil whine is the PSU & GPU. If it's that then there's nothing you can do about it without just replacing it.

 

Though it's audibly displeasing it doesn't hurt the system in any way.

 

Though if you have a different PSU there's still a standby 5V going to the motherboard. Something on the motherboard might be producing it though I've never heard of this.

Will try it, thank you for feedback

Coil whine. Not thing to fix.

I would not recommend that hard drives be shaken in either the on or off state as it could cause damage to the sensitive moving internal components of the drive lowering its lifespan or causing it to fail and the data it contained to be lost. If the hard drive can be identified as being the cause of the noise when powered on with isolation of other sound making components then that has the potential to be a sign of failure and is an indicator to back up important files on the drive in case of failure. Fans can cause buzzing if they are jammed and that is hopefully the cause of the noise which can be easily fixed using compressed air to blow the dust off the fans.In certain systems (if noted by the manufacturer and the sound was there in the past) is normal as in its operation although the main concern for the sound would be the hard drive and any data that it holds.

That could be the cause although there are many components which have the potential to make the sound and isolation of each individual component would be how to indicate the cause of the noise.

I said jiggle. Not shake them like a red headed step child.

Or other solution:

@MarTorb Back up any important data that is on the hard drive. (If it is indeed the HDD, then this can mean that it is dying.) Then with the computer turned off, remove the hard drive from where it is mounted and carefully place it on the bottom of the case, maybe on some foam rubber or cardboard. Then power back up and see if the buzzing persists and is coming from the hard drive. You should be able to confirm if it is the hard drive by touching it with your finger to feel any vibrations.

 

Besides the PSU, GPU or HDD, this could also be caused by bearings on the fans. It would be easier if it where the fans as they are much easier and cheaper to change. I would suggest booting up with the fans unplugged. If this works then one at a time plug them back in and then by process of elimination... tadaa you have your answer. If not try booting the system with the side off, your head inside the case and listen to where the buzz comes from.

I just bought a new a harddrive and don't have any important data on my old one. I could just take it out and see if that stops the noise, but the noise is still there even if the computer is off it, can it still be the fans?

Do I understand you correctly that, if you switch the computer off, the noise is still there?
