All in one

i have an all-in-one and it makes a humming noise.  I've tried to resolve the issue, but the directions to fix it doesn't work.  I am sure it's owner-operator error! 🙂

There are several components inside an AIO that can make noise.


If there is a hard drive, instead of an SSD, it can make noise -- but that is nearly always a very low-level clicking sound, and an AIO that I have access to does have an hard drive, but it makes no sound.


The AIO also has as fan, and that usually makes a whirring sound, but if the bearings are failing, it could be vibrating and that might sound like "humming".


Unfortunately, there are no diagnostics you can run to check out the fan, so you would have to take the AIO to a local repair facility to see what they will do -- and they will charge you for examining it.  If the fan needs to be replaced, that could be quite expensive, depending on how much they have to remove from the AIO to get to the fan.


Also, some AIOs have optical drives for reading CDs and DVDs -- and if you have left a disk in the drive, it will automatically spin up and that can make a humming sound.
