LCD monitor making high-pitched sound

Q: LCD monitor making high-pitched sound

My wife's Samsung LCD computer monitor (which has a laptop attached to it) recently started making a high-pitched, mosquito-like sound. It comes and goes, but is there most of the time. If we shut the monitor off and back on, the sound goes away for a minute or so. We've moved the laptop away from the monitor, in case it was some sort of interference noise, but that didn't help. (I do plan to swap her monitor with another in the house soon.)

Is her monitor going bad? Something else going on here?

Video recorded with the odd sound. you may need head phones and a lot of volume to hear it clearly. The dominant sound is just the GPU fan spooling up.

Strange sound from my GPU during ATi tool run. - YouTube

I know its something electrical but other than that I have no idea. It doesn't seem to hurt anything but it is annoying. Its also exclusive to ATi tool and [email protected] Games and graphic benchmarks don't produce the sound.

A:PC making an odd high pitched sound during ATi tool test.

To me it sounds like a bad fan bearing.
I would open up the case and run the test again to make the sound start again, then go to the case and listen around the case for the source of the sound.

I recently got a replacement XPS 13 due to my first one having issues with high-pitched noise coming out from somewhere inside. Technicians and Customer Service couldn't point out the culprit so they replaced the laptop altogether. And now I am having the exact same issue on my replacement machine. I see from different forum posts that this issue was discovered as early as May/June 2012 and it is still out there. I assume this might be "standard", but people don't notice it due to the frequency. 
For such a premium machine with a pricy tag on it (the model I got: i7, 8 GB RAM, 256 GB SSD (1080p edition btw) was priced at NOK 10495 with standard options) you'd expect such issues to be non-existant, if not fixed by now. 
I LOVE the XPS 13 in every aspect possible; the lightweight construction, premium feel and solid performance. But I'm often in very quiet areas with this machine, and the noise drives me insane. (I'm a student)
What to do?

Hi Karl Sindre Baath Engelstad,
I am sorry about the frustration. I suggest that you flash BIOS from the following link:
Note: While flashing BIOS connect the Ac adapter and make sure the battery has minimum 15% charge as this needs uninterrupted power supply. Do not use the system till it restarts and comes up to the desktop.
In case issue persists even after flashing BIOS to the latest version, kindly send me a private message with the system service tag. Click on my name and click Start Conversation to send me a private message.

I have a Gigabyte 970A-DS3P motherboard trying to overclock a AMD FX-6300 @3.5Ghz CPU. I watched this video and copied all the settings down to try to overclock to 4.0 Ghz since I'm very new to this but heard it's very easy to do. However after saving the setup, a high pitched noise started to come from my motherboard/cpu. So, I went back to undo the voltage boost and core clock boost to see if that was the issue but the noise was still there, so I reset to the default settings and it stopped. What thing did I disable initially that started making the noise?

One night I come home, and I hear a consistent noise coming from my speakers, which are built into my monitor. I was too tired to deal with it so I turned off my PC and went to bed. Next morning, same thing. After a restart, the problem seemed to magically disappear. Now, after another night of my monitor being turned off, problem re-appears. I've tried rebooting the PC and monitor, plugging it in and out, nothing helps. I can still hear all sounds perfectly, they're just accompanied by the noise.
Also, just muting my system doesn't make the sound go away, so it's not a software thing I suppose...
And if my PC is turned off, or I switch to, for example, TV or HDMI input, the noise isn't there.
Any ideas?

A:Speakers making high-pitched buzzing noise.

Do you have a different set of speakers, or even headphones that you could try in the same port that the speakers making the noise are plugged into? I would check this first. Next, do you have a wireless router, or cordless phone sitting close to your speakers? If so, try moving those further away.

My laptop seems high notes. When the laptop is plugged in it is all good. If the laptop is running on battery it seems different high-pitched sounds. It is very disturbing because I work in silence. I checked if it is not a problem with the screen, but it's hard for me to judge. When the screen is turned off, and connected another monitor that everything is okay. It is independent of the operating mode and brightness. Squealed as I work without a cable. Maybe it's the fault of the power supply? In my opinion, the hardware is faulty, but if the complaint is accepted and the error is corrected? Laptop has three days ... Sorry for my english... PS: This is not hdd for 100% I konw how it sound...

Hello all, I have recently purchased an HP Envy 17 Notebook Touch and there is a noise coming from somewhere on the inside of the laptop under the keyboard that is a super high pitched noise. I have done tons of research on how to stop this noise. So far I have tried disabling the idle processor but I failed. This is okay because I would rather fix the issue without having my laptop's fan running crazy all the time.Then I updated the BIOS to F .30 and the noise goes away and everything is perfect! Then a couple days later the noise returned and I couldnt figure out how to basically reactivate the BIOS update so I just updated BIOS again and the noise went away. However, the noise has recently returned again and I am getting sick of updating my laptop everytime I want this noise to go away.Is there any possible solution for me to get rid of this noise? I think it is a simple software issue but I need something more permanent.(Also I bought this PC because my Mac isnt good for engineering school and this HP has 16GB RAM, a graphics processor, and the i7 - 7500 Core Intel Processor so I thought it would be amazingly fast and it is but thus fast it has caused nothing but problems for me)

When I put my computer to sleep, it stops, and it starts as soon as I turn my computer on. Changes frequency right before the login screen comes on, and then it stays the same after that. My PC also takes a while to start up now. I have to shut it off and back on maybe 2-3 times before it'll boot up. Just a few minutes ago, Windows sent me to this uh... resume(?) screen that I've NEVER seen before.

Are these 2 things completely unrelated? Could I possibly have a virus that's causing this?

edit: it also changes frequency during windows' admin program run notification

I occasionally try using an app (Cortana, audio recording from the mic, etc) that uses the mic, and find the don't work because the audio is converted to a high pitched, fast chipmunk sound. It hasn't happened often enough for me to figure out what is doing it and repeat it. It's just intermittent.

I didn't have this problem before going from Windows 8.1 to Windows 10, and it still happens after the anniversary update.

It's easy to fix by disabling and then enabling the mic in device properties window, but I just want it to work without having to do that.

My dad was the last one to use the computer and now he's gone out so I don't know if this problem was there when he was on it, although he didn't say anything to me.

But now that I'm on it, I've noticed the sound output sounds different. When I loaded Windows, the traditional Windows login tune played...but it was all high. It's not the volume settings, it's actually a higher sound, and this is actually affecting every single piece of sound coming out of the speakers on the monitor.

I tried playing a song and the guy's voice is all messed up - high-pitched because of this.

I don't know why it's done this or how to solve it. If anyone can help I would be very happy! Thank you in advance!

Hello everybody,

I have been having a huge problem this last month with my computer, which I hope someone will be able to help me with.

The problem:
A high pitch ?squeak? sound is coming from ?inside? my PC. It appears to be coming from my graphics card or somewhere above on the motherboard. I am not a hardware geek at all, so in all honestly I really do not know. I am almost sure it is NOT coming from my fans or my PSU, though it does sound like a voltage problem.

Here is a VIDEO I filmed of my PC making the annoying sound:

The facts:
The noises are random ? and not related to anything. They will appear when I?m doing nothing, and they will appear when I?m doing loads of stuff.
The noises last between ~1-7 seconds
The noises started occurring AFTER I installed my new SSD: http://ocz.com/consumer/vertex-3-sata-3-ssd - I had never heard them before. I cannot RMA it, unfortunately. After installing my new SSD, I formatted my PC and installed Windows and that drive. Note: I am almost 100 % sure that the sounds are not coming from the SSD or HDD.
NO sounds during startup or in BIOS
People can hear the sound through Skype, EVEN WHEN MY MIC IS MUTED (!!) I find this very odd, and I hope it might be something to help locate the problem.
Some days there are sounds all the time, but I have tried going 5+ hours without sounds.

What I have tried already:
I have tried unplugging my secondary HDD.
I have tried disabling EIST... Read more

If anybody can shed some insight, it would be most welcomed. I've encountered a few things in my computer life but this one well... please read.

My system first off...
P4 3.0GHz, 865PE, P5P800, 400W Power Supply, some mid size copper fan sitting on cpu, ATI x800 AIW, Bluetooth keyboard/mouse...
My cpu used to cook at high temperatures, that's prescott for you.

Went to the store, got a case fan, compressed air, and a new hd.

Cleaned it up, mounted fan and installed hd. Didn't really notice it at first, but then started to hear this high pitched sound. Rebooted, same thing..
Finally can't take it anymore, opened the case, and it seems to be eminating from near the cpu. It usually happens when it's taxed but the kicker is...
it always happens when i move the mouse. It sounds like crickets almost.

Anybody have any ideas? I cannot see it being the new hard drive, it is not in use yet. (original and new are SATA if it's relevant).

Thanks in advance,

A:High pitched sound

Thats an odd one, I would say it was the HSF (heat sink fan) for your CPU but since it happens when you move your mouse, it must be either the mouse or the CPU itself... Try using a different type of mouse (ie PS2 or USB). If this doesnt solve the problem, check to see if everything is plugged in properly (actually you should do that before mouse)... And if that doesnt work, see if you can swap your CPU over with another one to see if this is the problem.

Hi, I just got this monitor the other day. It's a great monitor and all... when it's on. When it's off or in standby mode, there is a really high pitched ringing coming from inside... only noticeable if the room is quiet, which in most cases it is (night time, can't sleep!)

Anywho, it only happens if the monitor's power cord is plugged in... if I unplug it, the ringing stops within 5 seconds, or if I turn it on, it stops. Either way... the ringing sounds like if you left your TV on... and you know it's on so you turn it off, quite annoying yes.

Anyone know of a solution that might be of help to me? I really like the monitor aside from this.. I'm even resorting to just leaving it unplugged unless I'm using it, so that it won't ring...

I've noticed, recently, that my computer makes a high-pitched sound, but there's more to it than that. It only seems to appear whenever the monitor is displaying a large amount of white or bright pixels. I'm talking about having notepad open, visiting this website, anything that uses bright colors. This is by far the most weirdest thing I have come across, yet. Even more so than my browser disappearing when I change it into windowed mode. Can you give me some tips on what I can do on this really strange case? Thanks in advance.


EDIT: Actually, it does something different. The monitor kind of "gets used" to the pixels on the screen, and when the colors drastically change (i.e. opening up other windows with dark colors), I get the noise again. So, now it's "used" to the bright colors. If I visit my darker website, it starts making the noise, again. So, what do I do about this?

I bought those speakers a week ago, plugged everything into place and I noticed an annoying high pitched sound when there is no sound output (I can also hear it when the speakers are on low volume). I gave them back and got a new pair. Sadly, the new pair has the same problem. The sound persist even when not connected with an audio cable. Tried switching power outlets and connecting in other rooms but it's still there. The only solution is to mute the speakers (press both volume up and volume down) Any help would be appreciated.

Hey, I'm getting some sort of feedback from my speakers. It seems to only happen when there is no music/sound playing. Where does this come from? Is my sound card picking up feedback from moving parts inside the box? Is there a conflict with the onboard sound device (if so, how do I disable this or even check to see which one is "running the show")?

Things I did since the last time I can remember not hearing feedback:

Upgraded motherboard ASUS A7N8X Deluxe
Added wireless headphones (nice ones from Sony - about $180 - but not sure of the model)
Upgraded to WinXP Pro from 2000

Hi RunOrDie,

Does noise stops when you disconnect the both mouse and keyboard. If possible then directly connect them to the system without using the USB extender and let us know if the noise occurs.

Also, if it is whirring noise then it could be from fan and you should check for vents to clear any dirt blocking the fan.

Keep us posted with the results so we can advise you further.

Hey, I am wondering if any of you can help me. Originally, I had a problem with my Nvidia GTS 250 graphics card, the cooling fan came loose and with me still persistently using it then after the fan fell completely off (stupid me I know). To prevent any more damage, I decided to unclip the mains socket from the graphics card (the 6-pin internal clip) so that my computer would automatically boot up with the on-board graphics that my motherboard (Gigabyte S-Series GA-G31M-ES2L) provided. The only problem I have got is that every time I switch the computer on there is a very high pitched, rather loud ringing sound. It's a brand new motherboard so I can't see how anything has broke on that. I haven't as yet changed any of the settings in the BIOS nor have I taken the graphics card completely out (it's still in the express slot of the motherboard) if that can help with the solution to my problem. Thanks for any help and if there is any threads relating to this I would be grateful if you could send me in the right direction. Thanks again,

Hello, this issue has been affecting me for the past few months. Every time that I think I fix it, it will eventually come back.

What it is exactly is; I can be doing anything, playing a game, watching a movie, listening to music, or browsing the web. Then all of a suddenly, the sound will mess up, and go from a high pitch to low pitch, then back to high.

It's not OS related, it happened to me while using windows xp pro 32bit, then xp pro 64bit. Now it started happening again the other day, and I'm currently using Windows 7 32bit - Build 7100.

PC Specs:

CPU: Intel® Core™2 Quad CPU Q6700 @ 2.66GHz (4 CPUs), ~2.7GHz
Motherboard: Asus P5N-D
Ram: 4GB
Video Card: Nvidia GeForce 9800 GT
Sound: Using Creative Fatal1ty USB Headset

When I was using XP, I could fix it by closing out all running programs, but it would eventually come back.

I've been using windows 7 for the past few weeks. It only started happening a few days ago, after I installed some Logitech G15 keyboard drivers/software. After it happened, I removed what I installed, but yet it just happened to me again a few moments ago. Was watching TV, came back to the PC, put on headphones and hit play on winamp. Next thing I knew I was listening to Alvin and the Chipmunks.

A:High-pitched sound from system(almost inaudible)

Turn off or unplug your speakers first. All sorts of spurious responses to whatever is going on can cause odd sounds from sound system. Then use a piece of 1 inch rubber hose or tubing to listen (as in a stethoscope) for noise from the power supply fan, or cpu fan. Check also the video graphics card if it has one.
Take a can of difluoroethane gas (dust off, or similar) and clean the cpu heat sink and fan of dust and hair.
Look over your wires inside the case to be sure none are hanging loose and intermittently touching the inside wall of the case.
Look for sound or video changes from some of your installed software, and particularly with games.

A:Annoying high pitched sound coming from my pc?

This sort of high pitched noise is usually a vibrating coil. Unfortunately coils (aka inductors) are common components on motherboards, graphics cards and PSUs.

Are you 100% sure it's coming from the PSU ? If so there's not much you can do except try to ignore it or get another PSU.

It could also be a worn fan bearing. Try to locate it exactly.

On the system startup, my speakers suddenly produced a high pitched beeping noise. I've tried using a different set of speakers, but the result was the same. I'm not sure what exactly is wrong, but I had recently installed a more updated video driver and a wireless keyboard/mouse.
I've tried uninstalling both the video driver and the wireless set (switching back to the old keyboard and mouse), but there was still the beeping noise.
Surprisingly, when I mute the master volume the beeping noise stops. Also, the noise applies only to the input speaker (the speaker which has the cable connecting to the computer) and not the other one. I am able to listen to music using the other speaker, but the volume is drastically lowered.
My guess was that there was something interfering (such as the wireless mouse and keyboard) with the sound card(?), but since I have uninstalled them (now using again because it is obviously not the problem) and there were no changes, I have no idea what could possibly be wrong.

Is there a solution to this problem? Help will be gladly appreciated.

The whistle is either heterodyne noise or your picking up sound from a microphone type source.

Do you have a microphone plugged in? If so try tapping on it and see if the tapping comes across the speakers.

Try taping the unit, do you hear the results through the speakers?

You may be picking up cross-talk through a poorly filtered circuit, this may be caused by poor circuit design.

Try going to your audio properties and adjusting the line-in volume to see if this noise changes in pitch.

Make sure you do not have any wires or devices close by that are connected to or in the direct location, that can be causing the white-noise issue.

Broadcast Radio stations or continuous carrier devices can cause this issue to happen, it is RF interference.

You could have the device near a televison or other device with is emitting RF interference.

Make sure the electrical wiring in the house is polorized and grounded properly.

Kind regards.

Hi there,

I just installed a new motherboard today, with a new graphics card. Everything seemed absolutely fine until I noticed a very high-pitched sound coming from the tower itself. I can hear it better when I go to the back of the PC and listen up close. It seems like it's not coming from the PSU (It can't be as I've swapped another one in and it still makes the sound) but from the motherboard itself. When I unplug the LAN cable from the back of the PC, the sound decreases in pitch. When I turn off the computer, the sound stops. As soon as I power back on, the sound starts again.

I can live with the sound, it's not too audible over the fans, but I just want to know if it means my motherboard is imminently going to fail.

Thanks in advance!

Oh, and the motherboard is this: http://www.ebuyer.com/product/131187

The new video card is a GeCube Radeon HD 3850pro.

There is a high pitched sound when the volume is turned up or when the laptop is being closed. When the volume is muted there is no noise at all.

So my computer is a few months old. I have had issues with the sound stopping working randomly and the only way to reboot it is to restart the computer. That has been going on as long as I have had it. Reciently however, it has been making this really high pitched beebng noise when I am playing videos on it. The beep seems to get louder as I turn up the sound and it only happens when the speakers are working. I thought it may be the computer over heating but a fan on it hasn't stopped it yet. Any ideas? I really like this computer but I'm afraid there is something wrong with the speakers.

Ok,so basicly,the problem is that I keep hearing a really annoying,high pitched sound coming out of the desktop computer.I don't hear it until I play some games(not all of them) for like 1 hour.Okay,so today I was playing my football game on the computer ,when I began to hear the high pitched sound.I pressed ctrl+alt+del and I found out that my CPU usage was at 75% and after I stopped the game it went down to 5 %.The game consumed only 458mb out of my 4gb ram .I think it has to do something with my CPU,but could you help me and try to explain me what's the problem of my computer?Please,if you have any misunderstandings regarding my problem,tell them here so I could relate more about it.I'm not much of a computer wizzard and nor am I a good english speaker,but I'll do my best to try to communicate with you.I really want to know what's causing this sound.

Remove the left side of the case and watch/listen to identify where the sound is coming from.

*2.93 GHz celeron
*Intel PERLX mobo
*WinXP Pro
*Nvidia 6200 GPU
*Usually 3 HDDs (only 2 work)
*Used as media center PC run by SageTV

I have had this setup (3 HDDs) for 1+ years with no issue. Then one day I went to the PC and it was frozen with a high pitched sound coming from the audio - the last image was still on the screen and there were no error codes - no keyboard response at all. I had a set up of IDE1=boot HDD and CD drive, IDE2=2 storage HDDs.

so, i removed one of the storage HDDs, and it became stable again. So to troubleshoot, I put in a new IDE cable on IDE2, added the drive, but got the freezing again. Replaced 500W PSU with another 500W PSU - still freezes. Got a SATA HDD, and left the one drive on IDE2 (Ithought for sure this would fix it) - but again it freezes (BTW, I confirmed all storage HDDs are fine on another computer).

No other hardware or software changes were made. Why would it work fine with the 2 drives (1 storage) and not with 3 drives (2 storage, either PATA or SATA)? Any ideas?

Ok, so around Christmas of 2015 i had my graphics card die on me and in a mixture of me not understanding that it was the graphics card that was dying and being slightly frustrated i shut my computer down by pulling the plug. This resulted in an almost useless PC as i guess i interrupted something important. I spent countless hours reviving the computer and finally saved it by rebooting the BIOS through a USB-flash drive. However i've had a tiny but annoying problem since then. All sound i record or input (skype, discord and other chatting sites) is now high pitched and the overall recording sound is generally bad. How did this happen? Was there something wrong with the BIOS is loaded? Can i have damaged the internal sound card in the motherboard while tinkering in the machine, might there be anything wrong with my drivers or is it some other issue?

I should say i have a stationary PC with Windows 10 and the BIOS version i now run is: American Megatrends Inc. 1203, 24.05.2012. I am also terrified to go back into the BIOS in case i ruin the PC again so i hope there is an easier solution. Thank you in advance to every helping hand!

A:High pitched sound on all sound i input?

Wow... quiet a story there.
Have you tried removing the dead graphics card and if you happen to have a sound card, try removing it and re installing it ? That's what I would do first as its a result of brute force damage...lol

Firstly, apologies for the vague thread title, I couldn't think of how else to describe it

Right, when the monitor (rather old 16" Sharp LCD monitor) is showing the colour white (such as a Google search results page, GMail inbox etc.) I can hear a rather audible high pitched buzzing sound, no matter what brightness the screen is on. Any ideas as to why? I'm sure there is a scientific/electronic reason as to why, it's just I'm not sure what that reason is

A:Monitor makes a high pitched noise when showing white.

I have read that the condition can be caused by low quality capacitors.
And I understand the fix (workaround) is to lower the refresh rate as low as it will go.

Also could be the power inverter for the backlight (same reason: cheapness).
Some people say you can epoxy the edges of the inverter to fix this. Not advisable IMHO - just replace it.

And if the backlight is fluorescent, then you could be hearing that common buzz that fluorescent lights make when they are close to burning out.
