Only noise No sound but only a lot of noise

Is this a laptop or a desktop PC? The two common parts of a computer that make noise are the cooling fan(s) and the hard drive(s). Is the noise caused by air moving, like a hair dryer? or does it sound mechanical like a grinding noise?

Do you mean it makes the noise during the spin cycle?

sounds like a broken belt

Hi,

If you Processor is access info the CPU fan can also make lot of noise, Kindly check SMPS fan also due to Dust formation on both these fans can result in making sound.

The bushings to the front suspension are completely worn out. They must be replaced before the shock damage your other suspension parts.

Modems don't have fans.
I think you mean your fan in the computer makes a loud noise. Some computers have settings where the fan speeds up if you are doing a lot of things--making the computer work harder.
Some fans make noise just before they fail. Depends on the type of noise. If it's a sound that has a lot of rattling in it or maybe a high screeching sound, I'm thinking you'll be needing a new fan. Probably a CPU fan is the culprit. Also, fans on video cards often go bad--so you'll have to open the case and listen to where the sound comes from.

Can you describe the noise:
Water noise,
Mechanical sound noise.
Motor noise
Rattle noise

Sounds like the baffles have come loose in the tank. The only thing you can do is replace it.

the recorder does have two mic settings, hi and low. the high is great for lectures and the low is for personal dictation
