Hp is making a loud noise after being on for awhile

The PC sometimes sounds like a fan is overworking (starts as a low hum but then turns into a loud buzzy kind of noise) and it doesn't happen all the time. i also lost the sound around the same time this happened. do you think it's the power supply fan or the processor fan? i'm not familiar with the guts of an HP but will **** it up & open it with your guidance!
thanks for any and all assistance!

If you don't want to replace the fan, you can simply pull the plastic sticker label off the back, put a little WD-40 or sewing machine oil on in with the fan both off or on to get the lubricant in the bearings, then wipe off the oil around the surface and cut a piece of electrical tape to cover it from dust in the bearing. It will run good for years then.

It is most likely the processor fan which is getting busted or dirty.
Open the machine after having it unplugged and blow it all dut in machine and from both fans. Clean the fans with a soft brush and see if that works. Otherwise you will have to replace it. But normally it is just dirt

How can i repair a loud noise my hp iq506 just started making? the noise is on the left side of the screen and it sounds like a fan running and skipping?


Its probably exactly that, switch off and remove the access panels and you will probably find its full of dust etc. Find the fan, give it a good blow out with an airline or a strong vacuum and see what happens. Replacement fans are a few bucks and take a good DIY person a few minutes to change. Look online for your make, model, serial for compatible fan.

Loud grinding or humming noise


It sounds like you have a fan with a bunch of gunk on it. Get a can of compressed air and clean out all the vents and fans.

Also, take a close look at your video card's fan. It might be the culprit. Many times when they are about to die they make a lot of noise...

you have a ball bearing fan, after awhile, the fans ball bearing move around, thats were you are hearing the whining noises. All you have to do is replace the fan with the high piched sound.

The Sound used to increase over a few hours. NOW the machine starts up REVED.... When you turn it on after letting it cool, it's silent until you start Windows, and the noise picks up a little. You...


Hello there! Noisy Sounds can be much frightening, but if you could determine from where the sound is coming on you will get the solution, the sound makers inside a pc are mostly fans, and what type of sound you are actually hearing, rattling sounds means some wires touching up the C.P.U Cooler fan, another one could be a loose fan on the SMPS. Solution to this is to Check all the Fans Do so by
1. Remove the Cabinet cover on one side and Start the machine and try to see and determine what actually is making the noise, rattling sound could be a wire or something touching the fan, if its okay, then listen for the SMPS fan.
Hope this Helps.

If it is the fan in the power supply, replace the power supply.
The case fan is easily replaced. Measure it (in mm) and purchase a new one. The standard fan is usually 40 mm, I think.

Desktop computer fan runs constantly


Hi,

Desktop fans do run constantly, you cannot avoid this.

The reason they get loud is because there will be a build up of dust on the fan blades.

To rectify this problem turn off the computer and remove the power cord from the rear. Then you need to remove the side panel from the base unit to expose the motherboard.

You will see that inside the case it is full of dust. Look at the CPU fan (the fan on the motherboard) also take notice of any case fans too, they are at the back.

To clean the fans and the case you can use a clean dry paintbrush or compressed air.

Once the inside of the case is cleaned you will see a noticeable drop in noise.


Regards.

Bad Fan... either the CPU Fan or the Power Supply Fan or the Case Fan. If the PC is older than 4 years it is probably the Power Supply.

Loud Humming Noise from Computer after installing new RAM accompanied by Monitor not turning on. What is wrong?


The ram is not the right speed for your computer. please pull it out and make sure it is the same kind you changed it out with. The reason for all the sound is this... When you first start the computer, the fan will be really fast. As it goes into BIOS the fan slows down. So the noise stops. I know this for a fact though. I have gone through this with my computer. Also make sure the RAM is locked in it's ports and the white things are locked at the ends of the RAM. This will solve your problem. Good Luck.

Buzzing/humming noise in my computer's power supply


I wouldn't recommend leaving your PC on all the time but don't think this should have harmed your new power supply. The power supply may be faulty so try speaking to the store you bought it in to try another one. Alternatively, I would try moving your PC to a very well ventilated area at your desk to see if this helps.
