Solved: PSU fan making strange noise

Q: Solved: PSU fan making strange noise

Hello this is my first time here and i hope i am posting in the right section. I checked the search option but couldnt find the same problem as mine.
So lets start i spent last night(about 12h) rendering images on my pc(which is less than 2 years old)
so after it was done evrything functioned nicely and i didn't notice any problems when i turned it off.
After around 3-4h i turned the PC on again and it started making some strange noice like crawling or whirling or something not sure how to describe it correctly. So i opened the PC and while it was all running and making the noise i used a screwdriver to block all of the fans for like a sec just to see if it is them (i read that from some other forum suggestion).
So anyway when i stoped the PSU fan the sound stoped and when i released it did not start immidiately. The sound does not start as soon as i start the PC it takes some time for it. Also the fan seems to slow down when it happens. Now i left it on like 10mins with the fan making the noise and slowing down and after like 5-10min the noise stoped and the fan started turning fast again. It has been several hours on since than and it is working normaly, i read that the problem could be dust/a wire out of place/a insect flying in etc. My concern is what i should do, is it the PSU failing or just the fan or maybe something else?

My computer running windows xp 64bit has been freezing. When it freezes it plays the last half second of sound played over and over very quickly, sounds like a machine gun. It happens both when gaming and doing nothing. Usually it unfreezes after a few minutes, only to freeze again. After roughly 30-40 minutes of this, the freezing usually stops.

Sometimes it does not unfreeze, and I have to hardboot. Windows will freeze when booting several times, safemode freezes after loading SPTD.sys, even after hitting escape to cancel loading.

AVG free, Avast, Clamwin, and clamtk (scanning my windows partition from linux) all pick up no viruses.

This happens with both windows xp home, windows xp pro 32bit, and windows xp 64bit. Linux does not seem to have any problems.

I've tried updating all my drivers, fresh installs, everything I can think of.

Anyone have any ideas?

A:[SOLVED] Strange Freezing - Sound making machine gun noise

No, it isn't a virus. It could be (1) temperature or (2) voltage—among other things.

Do be sure to check your temperatures in the BIOS in any case, because you want to be sure you're okay there. If the temperature is 30? C or anything like that, you've ruled that out. It's in the BIOS under Health, and look at the CPU and the System temps.

If your voltage is, say, 0.1 too low for your needs, you could have trouble. Overclockers can often help "ordinary guys" tweak their voltage settings the way that is exactly right for your RAM.

Then there is the possibility that a drive is not doing things just right. It would not have to be the drive you are using. For example, a CD-RW that works just fine might nonetheless have an operational problem that upsets the system, especially if it were on the same cable as the hard drive. You might never to think of looking for a drive that isn't in use at the time. Therefore some people would try subtracting all the hardware you are not using, piece by piece, to see if it goes away.

There is also the question whether it happens in Safe Mode. If your drivers are okay, I would guess it DOES happen in Safe Mode. But because Safe Mode installs just what you really need, it can sometimes suggest a solution in a backwards-thinking kind of way.

Finally, you mention quite a few anti-virus/firewall programs there. You are running just ONE firewall and you are running just ONE anti-virus program, right? If you are running more than ... Read more

I've had this computer since March and I'm using the stock heat sink it came with. Recently I've noticed that sometimes programs will be unresponsive for 4-6 seconds and then it will go back to normal. The same thing can be said about the mouse, sometimes it doesn't even move. I took apart the side panel of my case and noticed that the CPU fan was making the noise. It sounds like a dial up modem, but a lot more silent. This noise can only be heard up close and eventually it goes away before starting to make the noise again. My CPU temps are normal, 31 on idle and usally 45-50 when I'm playing a game. The stock fan never stops spinning either. Maybe the motherboard has something to do with this? I haven't changed anything or added any new hardware since putting it together in March nor have I replaced the thermal paste because the temps were always low to begin with.

So this is the first time (for about the past week) that I've heard my mobo's fan making a pretty noticable noise. Upon inspection it seems like the fan is spinning, slowing down, speeding up, slowing down..etc... Not sure what to do (and whether or not to start panicing).

The system is a Gigabye GA-7VAX with the KT400 chipset. The fan is directly on the chipset so I definately don't want this baby to die. Any ideas?

My PC runs Windows 7 x64 and is basically an Asus H97I+ M/b, I7-4790K CPU & GTX970 GPU. There are two SSDs for hard drives...

Whenever I am running MS Flight Simulator, I get a strange, high-pitched 'chirping' noise from what should be a silent PC, fans apart. After Googling I kind of decided it was coil whine from the GPU:

GeForce GTX 970 Coil Whine Concerns | PC Perspective

but having opened up the case and listened more closely (literally) the noise seems to be coming more from the CPU. If so, what could it be? Pretty sure it's not mechanical (i.e. fans).

Oddly, as I say, I don't get the noise other than when I run MS Flight Simulator (I don't use this particular PC for much else). I tried stress testing the CPU with Intel Burn and the GPU with this:


..also copied large files from one SSD to another. None of which caused any noise at all. It's only when running FS9 (haven't tried FSX). Makes no sense to me. Recording of the noise is here:


Any ideas??

Hey guys, this is my first post here so if this is in the wrong place, then forgive me, I checked around and this seems like the best place for this kinda prob.

Ok the problem is that my fan on my graphics card (Radeon 9600XT) has started making a weird and very annoying buzzing/whirling sound.

It all started after I did my monthly clean up inside my system. Getting rid of all the grime and stuff and checking to see if everythings just all right.

Well i plugged everything back together and a strange whirling sound started coming from my system. It's hard to describe really, it's kinda intermitent. It comes on for 5/6 seconds then theres a pause, then it's on again for another 5/6 secs etc. It doesn't seem to be related to any sort of activity the computer is engaged in, ie it makes the same kinda noise when just sat there on desktop as it does when Im downloading stuff, browsing the net or playing games.

I took the back off my case to see what it might have been and found out it was my graphics card, because when i held my card the pitch of the buzzing would lower a bit, so I took the top of my fan off my g-card and cave it a good clean out because i thought maybe there was something stuck in the fan that was making the noise. The fan is now totally crap-free but it's still making the noise.


If anyone has any suggestions please help It' so very annoying and starting to give me headache. Oh and if I've left out ne information ... Read more

I am new on here and still figuring out how to navigate the forums, so I apologize if I'm posting a question that has already been asked (also english is not my first language so bare with me haha). I can't find any article/forum that explains my problem so I am posting here hoping to finally finding out what is causing this sound and how to fix it.

The sound happens almost always when I access my second HDD in windows explorer. Sometimes it happens when my PC is working harder than usual (HD streaming for example) and sometimes (not so often) seemingly random or when I am not even using my PC. It is hard to explain but it is a quick high pitched spinning sound followed by what I can only explain as a clicking sound. It is very quick only about 2 seconds I would say. Previously while playing The Sims 4 the same sound happened right before the game always froze/crashed.

I only know a few things here and there about hardware components, just the basics... I have read somewhere about hard drives "spinning down". Does this mean the drive temporarily shuts down and starts back up when you access a file from it? Or what does it mean? Could this be what is the problem? Or is it something else? I don't want to take my PC in if it is a problem I can fix myself, I am pretty good at following instructions to troubleshoot. I have already run tests on both of my hard drives with a program that checks the health of your hard drive and both my disks are still in e... Read more

Hey everyone.. New here have a critical question!

I was in the middle of playing some game about 20 minutes ago and my harddrive started making a strange buzzing/humming sound. To confirm it was my harddrive I unplugged it, and turned the computer on. The noise was gone when I did so. So I have it back in and everything and it "seems" everything is running a lot slower. Things are locking up, ect.

I'm wondering if anyone could give me an idea of what this problem is, and how long my HD might have left in it. I'll be monitering this thread so I'll try to reply fast.. Don't want my HD to die before I find an answer.

I'm still not too good at fixing my computer so bear with me. I recently had the Dell techguy out because my tower was making a noise like small jet engine. The tech replaced the power supply (2nd one), heat sink and fan. Fortunatley for me, it is still under extended warranty until June, 2010.

My question is that when I start and shut down my computer, there is a loud whoosh sound for perhaps a second or two. I never had this before the replaced parts were installed and am concerned whether this is standard.

My grandchildren play Wizard101 on it and sometimes it will crash (black screen). Would this online game make things worse? Is it worth upgrading memory or possibly video card? I have done a little searching on this but have read negative things about Dell's equipment & parts and what they recommend to upgrade.

A:Solved: New fan making noise

About a week ago, I started having some trouble with a really noise fan. I asked a friend, and he suggested that it might be a wire hitting one of the fans, so I opened the case up and gently poked around with the wires. Everything was cleared up. Now, the problem is back.

The noise sounds like a car engine; it's kind of a dull throb, occasionally speeding up during which it sounds like it's in overdrive. I need help determining which fan is causing the problem. I have a large CPU fan (came stock with CPU, don't know dimensions; processor is an E5200), a stock case fan, and the fan in my power supply. All I know is that this noise is coming from the back half of my case. I'm going to refrain from using the PC until I know which fan is causing the problem, as I don't want to risk damaging my CPU if it is indeed the CPU fan that is the problem.

I would guess that your power supply isn't giving you consistent power, but that's just a guess. To test it I would plug in a different power supply, if the problems goes away, that was it. If you have a tester power supply, or another comp you can pull one out of, that should work.

Hi guys, I've got a problem with my CPU fan. Everytime I do something that raises the CPU usage (like gaming or something) the fans starts to spin very fast and the case is unusually hot. But that's not all they are doing some strange, non-constant noise, something buzzy and it doesnt happen all the time. Only sometimes . I am afraid to open the power supply case to check if some wire is in the way of the fan :3 cuz I might break something xD. They are not dirty, Ive checked that. My PC is better than my friend's but his PC is soooo silent that u have to get your ear down to it to hear the fan spinning. Please help me ! Thank you in advance!

Hey all,

First timer here with very little computer experience. I've been browsing the forum via google, and I noticed a bunch of people had the same problems as I do right now. However, I have no idea if I have the same problem as them, and I would be grateful if someone walked me through this. I have a DELL latitude D620 running XP SP3. I use McAfee Total protection 2012.

Basically, in the past month or so, my CPU has been gradually increasing to the point where every couple of seconds it becomes 100%. The computer is still usable, but it overheats signficantly and I want to catch the problem (if there is one) before it becomes worse. The biggest contributers to this problem are services.exe and about 8 different svchost.exe running at once (sometimes ALOT more than that). These typically take up at least 50% of the CPU at any given time.

A:Solved: Strange noise coming from nowhere...:-??

The sound is probably coming from the internal speaker of your computer. This is a way for your computer to "complain" about something, to report a problem.

Open your case and try locating the sound source. Internal speakers are usually mounted on the case and connected to the motherboard. If you can't locate a speaker, look for a small rubber-like cylinder object, this could be the speaker as well.

Now, if you are sure that the sound comes from the speaker, we must identify the error code (aka the sound). Check the manual of your motherboard, you can usually find details regarding BIOS error codes there...Or try the manufacturer's website.

Upgrading RAM can cause problems. However, in that case you wouldn't be able to start your computer at all or you would be getting other error messages as well (like the infamous Windows Blue Screens of Death)...

IMO, your computer complains about overheating since the sound starts when you run games. You may accidentally moved the CPU heatsink while installing the RAM stick, who knows? Next time you hear this sound quit the game, restart and enter the BIOS in order to check the CPU temperature.

You can enter the BIOS by pressing a certain key (usually the DEL key) while the computer boots up. You will see a message like "Press DEL to enter Setup" on the POST screen, the first screen that appears when you start your machine, where information about your CPU, RAM and drives is displayed.

I started my computer today and heard a strange clicking noise on boot, it was a few clicks, it stopped and everything booted up seemingly normally. Windows loaded, but as soon as I got to the windows login screen, windows started going haywire with a constant arbitrary series of beeps. It looked like windows was trying to display an error message but it couldn't. The username and password text boxes became disabled when this started happening. I wish I had managed to catch a glimpse of the error message, but it is only displayed for a split second. After doing some research, I read that a "clicking" sound isn't likely to be produced by the motherboard or RAM, but it's most likely the hd instead. I unplugged the power and IDE cables from the hd and turned my computer on again, I still heard the clicking sound on boot, which leads me to believe there is an issue with the video card. The strange thing is, when my computer is booting, if a press a key when the clicking noses start, the clicking noises stop. Any help would be greatly appreciated. Here are my specs: Windows XP Pro SP2, DFI Infinity 975X/775 motherboard, Intel Core 2 Duo E6600, 2 gigs DDR2 800 PC2 6200 Patriot ram, nvidia geforce 8600 gts, antec 500watt power supply, 200gig maxtor hd.

My Maxtor One Touch 3 continues to work flawlessly, but it's started making a strange "breathing" noise, even when disconnected from the computer.

It's kind of a throaty noise that comes and goes on about a 7 second cycle, with 2 sec. "on" and 5 sec. "off". It sounds very much like somebody snoring faintly, with about that kind of rhythm, and it's just barely audible from 4 feet away.

I'm attaching a zipped mp3 recording that I made by holding the unmounted HD up near the built-in computer mic.

Does this sound familiar to anyone?

Wow.. thats a pretty funny sound. LOL.

Anyways, back to the problem.
First thing I would get any important data off the HDD. Strange noises from a HDD usually means impending doom.
Then go to www.Seagate.com to download and install their Diagnosis utility. (Seagate owns the Maxtor brand)
If the test comes up bad and the drive is still under warranty, contact customer support.
Otherwise, look for a new HDD.

I have now idea how I am getting this trojan! I use Webroot Spysweeper, Spybot Search and Destroy, Adaware (Spybot and Adaware are not yet downloaded and installed again), and Spyware Blaster. How on earth am I getting this thing?! What can I do to prevent it from coming back?

I have been downloading pictures from the "A" drive since yesterday, when the malfunction started. Any ideas why this is happening? I have Windows 98, with a Pentium 2.

A:PSU making noise

Are you 100% certain that the source of the noise is the PSU? If it's coming from the PSU fan I would start by first cleaning it.

If there is no dust at all I would be worried about any noise emanating from the PSU.

My girlfriend has had a Dell Desktop for about a year. In the last month or so it has started to occasionally making a very loud, almost grinding noise. She has one harddrive and a cdrom drive. I know it is usually a floppy, disk, fan or hd that will make this kindof noise. Unfortunely I have not had the occasion to be able to open it up while it is still making the noise. However this morning I was woke up by it and thought it would be my chance but I discovered that the pc was shut down and again the noise stopped before I got the tower open. I have the side on but unscrewed so I can open it up easily but I was wondering what could have been making that noise with the system shut down?

I think my cpu fan is going out on me, and I've never messed with my cpu before. My question is do I have to replace the heatsink with it or can I change just the fan?

If that is possible, where is a good place to get them? Thanks.

My 2 month old computer is sadly annoying me. The noise of it!! Its not greatly loud, but enough to ennoy me especially since I listen to so much music on my pc.
I have 6 fans, 2 on the psu which i think are quiet, as small one on the motherboard which Im guessing is silent, one on my graphics card which i think it pretty quiet too. Then theres the cpu one which obviously makes some noise but I've turned on 'quiet fan' so its only running at about 1200rpm. This leaves a huge big fan at the back and I think it could be this. I've felt the back and theres a huge suction of air. I want to know if this is likely to be the fan making most of the noise and whether you'd recommend replacing it and what with.
It doesnt help that theres a vent in the front and 2 side vents either but they must be there for a reason.
Note, I also have a fan on the side panel which isnt plugged in since i dont need it.
So any help would be appreciated, thanks guys!

A:Which fan is making the noise??

Yah, it can be hard sometimes to tell which one is the bad guy.

In general though, it is the smaller fans that are the noisy ones. Luckily, once you find which one it is, you can replace it. There are many excellent (quiet) fans on the market these days.

What motherboard to you have? I think the loudest fan on my computer is the chipset fan. I have the A8N-SLI deluxe, followed by my CPU (stock AMD) fan. My 12 inch case fans are SUPER quiet.

Hello, I have a Scorpio Series case and the side fan (fan that lights up orange and red, some other models light up blue) is making some small noise. This noise is a very low electrical noise that you might here if you were near some huge electric phone wires (outside). It is not consistently making noise, it just comes on and off. I was wondering if there is any way i can turn off this fan, or is there any other way to deal with this problem... I am not so sure if this is a big deal, but it just doesn't sound right. I have 4 other case fans, power supply fan, cpu heatsink along with a minifan on my video card, so turning off this fan i dont think would cause any major problems with my cooling.

A:Fan making noise... help

You can turn off the fan by opening the side panel and disconnecting it.

However, a better idea would be to simply replace the fan. They don`t cost very much, typically just a few dollars.

Regards Howard

I have an AMD Phenom II x4 955 cpu with the factory mounted fan on top. Have noticed lately that a pronounced noise (squeal) from the fan when viewing various sites with my browser. The fan speed adjusts with the content as expected. Now it is running @ 3900 rpm while typing this, but if I select a video to watch, it will climb to around 5600-6000 rpm. That is when it is making the squeal. I am thinking the bearings are dry or have become worn. Question is, has anybody changed their cpu fan with this type processor. I hope to remove the fan and replace without taking the cpu out of its socket. Attached picture of cpu/fan, camera shot "stopped" or made it appear that it was stopped. I used Speccy to monitor the fan speed, although the readings seem very high? Tx

A:CPU fan making noise

Replace the fan if possible, but I would just buy an entire new cooler.

When you remove it use a twisting clockwise counter clockwise motion to break it loose from the thermal paste before you pull up, this should keep the cpu in the socket.

Please, be careful

I have Thermaltake Toughpower 800W PSU! Its fan makes really loud noise when playing PC games! I tried to oil the fan like I did with my CPU fan, but I could not get to PSU fan without opening the PSU itself! Should I open it? Or maybe there is another way to fix this!

A:PSU making a lot of noise

You can change PSU fans, but it is not a job for amateurs.

Thermaltake power supplies are not known for being quiet as they ramp up.

I was wondering if any one could shed any light on the following problem.

When my PC is turned on but not being used, I occasionally hear the sound that is made when you click on buttons/web links. I am not using the PC so I was wondering how this noise was being generated.

Is my PC being used remotely, or is it nothing to worry about.

Thanks in advance,
