Where is this noise coming from? Help

https://www.youtube.com/watch?v=EiJrLpKcKf0 here is the video of the sound, Now it happens alot lately and no cords are touching the fans I took it apart and orgainzed cables and still I cant tell if its the GPU or PSU. I really am getting annoyed of the sound I bought this computer pre built from bestbuy over a month ago. A week in it started to make this noise

First - I did not watch the video. Most sound - as you are describing - comes from one of the moving parts. Since most of the moving parts are the fans - you can try to stop a fan momentarily to see if it makes the sound stop.

You have roughly 4+ types of fans. One in the power supply, one on the CPU cooler, one in the video card, and one or more case fans.

To test the video card fan - just remove it.

To test the case fans - just un plug them.

To test the PSU fan - block the fan blade from turning before you power up. It should power up and run for a bit without the fan running. you could find a way to force air through the PSU block just to be safe.

to test the CPU fan - simply block the blade with a pencil or stiff straw.

The idea is to remove one component and test - or test each component as able while the sound is being made.

It is possible to block any of the fan blades momentarily without damage.


Take this suggestion or not - it is not without slight risk - but it should help you isolate the sound or eliminate the areas for concerns.

Additionally - hard drives and DVD Drives also have moving parts to consider.

Sounds like a coil whine. Try the suggestions above, but it could be the vibration of a static part (see coil whine). There's no solution except to find which part does this, and replace it. Remove the video card, if it still makes the noise, it's the PSU.
