My Computer Is making Noice

Hi Everyone! Can anyone help me in solving my problem? My Computer is making much noice when I turn it On, right after 5-10 minutes. It starts making noice. Can you help me in this?

Apart from a soothing whoooosh of the fans and a reassuring prrrrprrprrrrrr of the HDD, computers shouldn’t produce much noise.

When they do, in 9/10 cases (ehm) it is a fatigued / overworked fan.

What kind of noise is it?

  • a rattling noise (like a stick against spokes of a bicycle wheel)
    – a cable is touching one of the fans

  • an intermittent clicking sound (like softly tapping a nail on a stone)
    – your HDD is dying

  • a barely audible high pitched hiss (like steam escaping or an insect chirp)
    – capacitor whine on GPU, the video card is being pushed hard and one of the caps is not doing great; you can get used to it or RMA it; usually not too worrying but if it gets worse, your GPU may stop working eventually

  • a persistent loud whoooooosh (like a hoover)
    – the machine is running hot, fans are spinning as fast as they can in order to dissipate heat; the cooling may be insufficient; perhaps it’s 30°C in the room and computers react strongly to high ambient temps; the fans are worn out or the grease has dried up; the fans, radiators, grills, filters are choking with dust and particulate matter - can be cleaned up easily
    – a computer running at 100% of its capacity will almost always make the fans go brrrrr real hard

  • it can be an animal stuck inside - may be dead , may be alive; a mouse / rat / hamster, bat or even a nest of small non-aquatic birds

Is the noise only present when you run the UE4 / UE5? Is this a laptop / desktop? What are the specs? Is it hot to the touch?

You’ll need to provide more info. Also not sure why you’d ask the question on this very forum…

Hmmm. My computer makes a chirping sound when in UE or when rendering lots of text. Looks like it may be the capacitor.

Nest of Birds. Gotta be!

You could run something like FurMark to reach a very high fps 500+ and listen to the coils whine. But any kind of sustained load will do - it’s generally a good idea to push things around when the GPU is still under warranty. I’ve returned 2 or 3 cards under RMA based solely on the noise they make when pushed. Including a 7990 that was hissing like a snake pit.

But yes, it does sound like it could be. Capacitors generate noise, it’s supposed to be inaudible to humans - so that’s another thing to consider :wink:

This may sound funny, but try vacuuming the vents. Perhaps your computer has become dusty and the cooling system is not performing well.

1st try what AdeolaO said. If that does not work. check those fans as Everynone has suggested.
if it is a cap or more then 1 cap, check your mother board for bulged caps (at the top) if you see that replace those caps(they are the cause). If you are capable of doing it, other wise to a repair shop. They can change them out easily. If that is not it, probably your power supply is low, caused by bad caps and causing it to chirp because its power is weak or the transformer coils ringing because it is being off frequency. So you end up hearing a hissing or squealing or chirping, depending on how it failed. Caps go bad in these boards all the time. â– â– â– â–  caps not made in usa. Anymore they only last about 3 to 5 years if that. If you go to a place called digikey you can get on their site and order from 2 thousand hour caps to 10k hour caps( lifetime length of the cap). If you want them to last longer get the higher length caps.

One other thing we ran into the other day, lady brought in a comp that was chirping, the cause was the ram needed to be reseated into its slots on the mother board, just turn off everything unplug the system take the ram out then put it back in try it again see if the chirping goes away. Good luck on resolving the issue.

Reason it can be heard is the caps changes value (which in turn screws up the filter of the filtered frequency) and the frequency changes so now you can hear it, it gets into our audio hearing range. The filter they were using which includes the cap as part of that filter Is not filtering the right frequencies anymore so it not right and in time, not long it will destroy other stuff. Most of the time they fail and turn into a resistor and 2 resistor do not make a filter, so it all goes wrong in that circuit.

Aren’t the Japanese ones widely considered the best these days, by pretty much everyone in the biz?

You know, Sanyo, Hitachi, Panasonic, Rubycon (spelling?)… The only US manufacturer that ever popped on my radar was Vishay but it’s been a while since I dabbled. Things might have changed in the last 20 years.

yes Japanese caps are the best these days. nichicon is about the best

Somehow I doubt OP will fetch their soldering kit and starts taking the mobo / PSU / GPU apart. @johnsteo776 Don’t.

yeah if you do not have the soldering experience. Take it to a shop or you will screw it up, trust me here(Main boards have multiple trace layers between top and bottom, can be up as many as 7 layers, if no experience soldering you will destroy those trace layers in between and be buying a new motherboard, unfixable if that happens). See it all the time, then i have a nightmare to fix, If it even can be fixed. :slight_smile: Then when you fix those you have to look at it as how did the guy mess this up, cause it won’t be a normal failure. Can be a pain finding the problem as the customer is never honest what they did. They think not saying anything saves them money. lol, just the opposite time is money.

Ha, so I looked them up, just to know what they do and I learnt about the: Capacitor Plague

Seems like Nichicon were not involved but, like, everyone else was…

Major vendors of motherboards such as Abit,[9] IBM,[1] Dell,[10] Apple, HP, and Intel[11] were affected by capacitors with faulty electrolytes.

In 2005, Dell spent some US$420 million replacing motherboards outright and on the logistics of determining whether a system was in need of replacement.

Yeah i think it is the metal they are using to make the part with and the metals being dug up or not as good as they were years ago (different part of the world), they break down quick. They seem to bulge a lot now days, back 20 years ago they never bulged you had to know how to find bad ones as they looked just a good a good ones. Today you can just look at them and see they are bad( most of them 80+%). Caps are a big part of repairs, that is usually what causes the issues. Most the time the customer sees the problem but lives with it until it gets bad enough to destroy bunch of stuff then they bring it in. because its dead and don’t work.

A tip for everyone, after about 2 years you need to re grease the heat sinks on all major components.
CPU, GPU. It dries up and cooks your chips and your just waiting for a failure right down the road. Lost 2 expensive video cards because of this.

How did you solve the problem?

Most likely, some kind of cooler has broken. Open the system unit and try to find out which one is making noise. I had this just recently. The cooler on the power supply began to make noise. I took it apart, smeared it with silicone grease, and then installed an additional “Cooler Master Hyper 212 RGB” cooler. I think it will not be superfluous, even if the summer is not hot.

OP never responded, for all we know he keeps the laptop on the dog, and it’s the poor thing that’s making overheating noises…
