Screeching noise

My son's computer sporadically emits a screeching noise that goes on for
varying periods. It is not apparently overheating and sounds as if it is
coming from the processor area but cannot be sure. He thinks it is some
alarm. Anyone got any clues?

Are you talking about a new build?

What do you mean by "apparently"?
Can you get into the BIOS? Is there a list of temperatures?

Do you see any error messages before Windows loads?

I suppose it's common sense that your computer isn't going to
screech for no reason. I suppose the only critical fault that might
produce such an error would be overheating or maybe the lack of a
critical component like CPU or memory. Have you tried re-seating the
memory?

Good luck.
 
No it's not new I built it about 2 years ago.
The temperatures are OK in the BIOS and sometimes the noise starts when it's
cold and just booted up.
No error messages.
I'll try re-seating the memory.
Thanks, I'll get back.
Regards.

From 28 years of experience with computers I can tell you the noise is
coming from one of the two or three cooling fans inside the computer.
The fans are built down to a price and so do not last very long. The
cheaper the computer the sooner they fail. And, the inside of a
computer gets very dusty which does not help. Provided the cooling
fans do not stop the noise is not a problem. However, if the fan
fails you are in serious trouble. If your processor is an AMD (an
excellent processor) then it can actually burn you main board and
processor. There are some many fan types and sizes it is not
something you can simply fix yourself. My advice is to take it to a
good (meaning someone who knows what they are doing not like one
response who suggested re-seating the memory) computer services
company and they will qucikly find the fan and replace it. If you are
in South Manchester we can help. My advice is to find a computer
service company who is a Microsoft Small Business Specialist as they
do have a good rounded knowledge.

Is it possible the noise is a fan noise ?

When a fan wears, the rotor can be off axis a bit
and with the extra friction, it vibrates. It may
stop when it heats up a little.

I'd take the side off the box and have a listen.
Place a finger carefully on the hub of each fan, and
see if a slight pressure, changes the note of the fan.
That may help identify which fan it is. It could be
the CPU fan, or a video card fan.

In terms of alarm sounds, a weird one is a "European
Police Siren" consisting of alternating two note
tones. That might indicate overheat or something
like Vcore is out of spec. I'm not aware of any
"screeching" noises coming from the case speaker
being used as an alarm condition. So it is likely
a fan.

With an emphasis on carefully, maybe using a flashlight.
Accidentally sticking a finger into the wrong side of a working fan
can be very unpleasant.

It's probably a fan. When you hear the noise, try to slow down the fans,
and see if the noise changes.

That is naïve. Assuming it's a fan, if it's a case fan, it can be
fixed easily by anyone who builds their own computer. Most here can
replace a CPU fan too, or the fan/heatsink assembly if necessary
(yes, including thermal paste).
My advice is to take it to a good (meaning someone who knows what
they are doing not like one response who suggested re-seating the
memory) computer services company and they will qucikly find the
fan and replace it. If you are in South Manchester we can help.

And your 28 years didn't tell you it could be a HDD, Optical drive
(unlikely), dodgy caps or something that could be causing the system beeper
to go off. And what is a 'screeching noise' ?- this could be different
things to different people.

And, the inside of a

Rubbish. The inside of a PC /can/ get dusty, it doesn't mean it willl. It
depends on the case used, the air pressure inside the case and the
environment the PC is in. We've got 2 PC's here in Antec P180 cases and they
rarely get any significant dust in them at all.

Provided the cooling
fans do not stop the noise is not a problem. However, if the fan
fails you are in serious trouble. If your processor is an AMD (an
excellent processor) then it can actually burn you main board and

/IF/ it's an older AMD, which this one is unlikely to be.

Shows what you know then. Unseated memory could cause the BIOS alarm to go
off, whioch to some could be a screeching noise.

So basically you're trying to spam your business. All I can say is I'm glad
I live in London and that I know how to fix PC's and therefore would never
need your company's help.

If the noise is coming from a speaker, it's an alarm.
I'd guess it coming from a fan and you can remove the fan, remove the
sticker, put a drop or two of thin oil on it, spin it around a bit so
the oil will work into motor bearings. That should fix it. Or you can
buy a replacement fan, they are cheap.

My guess is that it is the bearing(s) in the CPU cooling fan. I've had this
happen several times over the years. Replacing the cooling fan with
something that used ball bearings worked every time.

Bullshit. Only remotely complicated one is the PSU fan if you don't
just replace the PSU.

BWAHAHA. Do they ****. I've lost track of the amount of jobs I've had
sorting out the ****ups that so called SBS's have made.
 
Says you... I've gotten cuts off the blades on a 120mm fan
Click to expand...

Yup. Some of my case fan blades are sharp as a knife. I've had them
split a fingernail. Avoid it if you use your hands/fingers a lot.

Apparently you've already read the rest of the thread. Do you have to
repeat the advice that's already been given half a dozen times?

Dude, nobody cares, go tell some other group how to post . . .

Looks like at least two other regulars care, dude.

Nope, go write a book about how you think others should post, be sure to
inlucde a chapter on thread purity.
