IMac Making Strange Noise

Over the past few weeks, my year and a half old iMac9,1 has been making a strange sound. It's kind of like a clicking/buzzing/whirling noise. It's coming from the lower right corner of the computer. I can't tell if it's the fan or something else. It doesn't sound much like a fan. I've tried resetting the SMC, but that hasn't worked. It hasn't affected my computer speed...yet. The sound starts the second i wake it up and stops the second i put it in sleep mode. It gets louder and softer as I use the computer, and sometimes will stop for a little while. I'm just trying to figure out of this is something serious or not. I'm hoping this is something that can be fixed at my house, so i don't have to lug the thing to a Genius bar. Any help would be greatly appreciated.
According to iStat the fans are running at:
Optical Drive 1348 rpm
Hard Drive 1599 rpm
CPU Fan 1198 rpm

I have exactly the same problem, - this seems to be an issue of the first revision of these early 2009 iMac9,1 series.
Reseting SMC and every other doesn't help anything. Fortunately my iMac is under Apple-Care warranty.
It was now for three times in repair, - at last they changed the mainboard / logicboard. This has worked for a while (4 weeks). But now it started to make heavy noise again.
All very frustrating... Seems to be the harder issue than the infamous "iMac vertical line" symptom at the 17" iMac. If you have no Apple-Care you can throw the iMac away, - the repair cost will be more than $1000.-
Well, will bring the iMac a fourth time to repair, - will see what's happen...

Please Help :( iMac 20" refuses to boot up with anymore than 1gb ram?

Please Help iMac 20" refuses to boot up with anymore than 1gb ram? It was fine 4 days ago and had been working with a 1gb stick in one slot and a 2gb stick, which had replaced the orignal 1gb stick that I got it with, in the other and it had shown 3gb of ram and was working just fine with that since November? It went to sleep briefly 4 days ago while I was waiting on a customer and I came back to try to wake it up and it never would forcing me to hard boot it. When I did that it would only go to a black screen with a solid white light on the power indicator. Over and over again and same thing. I read and tried every suggestion I could possibly find in this and a few other mac forums to no avail.
I finally after reading about RAM issues etc. I decided to power off and take out the ram sticks and try them one at a time in each slot. So I took out the 2gb stick and did the SMC reset and it would boot up and work just fine with the 1 gb of ram. So then I went through the same process with the 2gb stick and it would not boot up only go to a black screen with white solid light again (NOT flashing). So then I tried the other original 1gb I had replaced with the 2gb and it worked just find like the other 1gb. So then I tried just 1gb stick in the other ram slot (back facing one) and with just the 1gb strip it booted up and worked fine. Tried it with the other 1gb stick and once again that one too worked just fine. So I determined it wasn't the slot itself I thought? I then tried the 2gb in the back slot and it would not boot only go to the black screen white solid light deal like before. So I thought well ok it's obviously the 2gb ram must have somehow went bad (even though I have only had it since November) and I thought well I will just use the (2) 1gb sticks in each slot and then that will at least give me 2gb because only 1gb really ***** LOL. So I proceeded to go through the same shut down process installed both sticks (I always push them to I feel them click and my fingers have a nice indention on them) reset the SMC and turned the power one and.... It would only go to the black screen with white solid light on power indicator???? I went through the same above process at least 3 times and again today a few times and I can't figure it out and I tried to search and search and I couldn't find anything like what I am experiencing.....What happened? Please help this slow Imac is killing me. It will work with 1gb ram only nothing more? Here are the specifics of my Imac.
It is a 20" Late 2006 Intel Core 2 Duo 2.16 ATI Radeon X1600 256 MB graphics card and Ram with now only 1gb (did have 3gb) and I am running OSX Lion 10.7.5
When I go to system report and go under memory it shows this:

Macbook Pro 15" right fan making strange noise

I have a mid 2012 15" Retina MacBook Pro, 2.3 Ghz with 8 GB of RAM running 10.9.4. About 3 days ago it fell on to tile floor from about 10 inches off the ground and hit the floor at a 45 degree angle. There was no damage except for a small scratch near and under the charging port. Everything was working perfectly until a day ago when I noticed the right fan was making a strange high pitched humming noise. It's very quiet, I can only hear it when there's no other noise but it is extremely irritating when I can hear it. Other than the noise the fan works fine, it speeds up when when the computer gets hot, and in Temperature Monitor nothing gets hotter than it should be. The computer works completely fine, but I'm wondering what could be making the noise. Any help or suggestions would be greatly appreciated!

IMac making beeping noises. Not during start-up.

My iMac is a 20'' Intel based. I got it early 2007, it was the generation right before they released the 24''.
I am running all the latest updates that I can find/am aware of.
My iMac is making beeping noises. The kind that come from inside the computer, alerting me about something bad happening to my hardware. It is NOT beeping at me during start up. It beeps 3 different tones at me. Not all 3 every time, but overall it will beep 3 different tones at me. There is no order as to how many beeps or what tones. The noise seems to be coming from the bottom left hand corner of the computer, if you were facing it like you were using it.
While I understand that something in the computer is failing or flailing, I cannot find any documentation or even forum posts on this topic. Every single place I search always yields pages about the 3 beep RAM notification at start up. This is very frustrating and not helpful.
Can anyone give me any more info about what is failing in my computer? Or at least stop my search and assure me that its something I will have to send it in for?
It makes the beeps the whole time it is running. Anytime a new webpage is loading, anytime I bring up my dashboard, anytime I open up a new finder window. Pretty much anytime the computer has to do anything. It isn't beeping as I type this post, but as soon as I click 'Post Message' it will beep at me.
I just reset PRAM or whatever it is they suggest you reset. I have reseated my RAM.
I am going crazy and need some help.

Run Apple Hardware Test (AHT) on your machine, it is on the original DVD that came with your computer or you can access it by holding down the "D" key when starting your Mac.

Please Help: iMac black screens after startup logo + spinning wheel no cursor).

Hi, guys.
I'm in a fair bit of a desperate situation; my iMac's screen seems to shut down every time after the white startup screen. The Apple logo appears, & the progress wheel begins spinning, then after a while - when it would usually then go to the gray login screen - it would, instead, go black. I can tell that the machine is still on (I can still hear it clicking as it does during processing) but I'm unable to determine anything else. Nothing is visible on the screen - not even the cursor - it's as if the display had turned off completely. I'm not sure if the login screen sits beneath that black screen (I have tried to log on by typing my login details in blindly, but even if it does log in, it's hard to determine what state the computer is in without seeing the screen.
I have tried the PRAM reset (holding CMD+OPT+P+R) during both the white startup screen, & the black screen to no avail. It seems unresponsive because I don't hear any additional chimes that I've been told should be heard during a PRAM reset attempt. I can't even be sure that the command is being inputted correctly because the light on my wireless keyboard remains off during the process.
I've tried rebooting over & over again; the results are the same.
The steps that led to the problem occurred thusly:
1 - I was trying to clear some memory from my current session, so I scanned through my active processes, quitting anything which seemed to be eating up considerable amounts of memory.
2 - One particular process I quit was 'launchd' which was functioning under my profile username.
3 - After quitting launchd, all opened apps seemed to close, & it looked like I was forcibly logged off the machine. The screen froze during this point, & I decided to do a hard reboot to log back in.
4 - The problem began after this hard reboot; startup seemed to occur as per usual; white screen > apple logo > progress wheel > and then suddenly, a black screen where the login screen should be.
I've shown a flashlight into the screen while it's black & it seems well & truly like the display has shut down while the iMac continues in the background. I have had issues relating to my screen going black before, but they were random & intermittent; they didn't occur without fail during the exact same time immediately after startup, & could be remedied by using the CTRL+OPT+EJT keys.
I am on an iMac 2010, 27", using I believe Lion OSX. I am unable to recall additional specifications while the problem persists.
Could anybody please help me? I'm quite desperate; I was in the middle of some urgent work that I need to get back to as soon as possible.
Thank you I'm advance to anyone with advice on how I can go about fixing this.

Gray screen appears during startup

Please help, iMac's bad display

I'm buying a computer for school in the next two months and I really need some help. I have been set on the 20in 2.4 Ghz iMac and now im reading so much on the screen quality and it being washed out towards the bottom. So now i dont know what to do, how severe the problem is, if it's being fixed, and what people are doing about it that have already bought these affected models. I made an account on apple.com just to ask this question so please help me. I dont want to have to buy a macbook justto have a better screen and I cant afford a macbook pro.

They're not doing anything. Another guy here on the boards has all but been in contact with the iMac engineering group and was basically told that it was "within specification." In engineering speak that means roughly, "you are S-O-L." They're not fixing it until at least the next revision.

Please help; iMac G5 connection issues.

Hello,
Granted this is not the first time I have had frustrating network troubles with these units, however this time I just can't seem to fix it.
We are running a couple iMac G5's 1.6 GHz, 512mb ram w/ Mac OS X 10.4.11, both have airport cards installed and have worked on the network before.
As of the other day they both decided they no longer wanted to be on the network and just sort of dropped off, nothing was changed on the computer end or the modem end. I have attempted running network diagnostics, resetting the modem, recreating locations, powering off for extended periods and even so far as to do a tcpdump with terminal commands. I just can't understand why these machines have such problems with networking and why it has to be so extremely frustrating to troubleshoot. Can anyone please help me with a run through of what this could possibly be and maybe a step by step to fix it, I may just be dumb or missing something but blah.
Thanks much

Change your router channel number. Most times this works & is all you have to do. Insturctions are inside your router user manual.
See KB Articles: http://support.apple.com/kb/HT1401 AirPort troubleshooting guide
http://support.apple.com/kb/HT2712 Using network locations in Mac OS X
============================
System Preferences>Network
Click the Assist Me button.
In the next window that pops up, click the Diagnostic button & do the necessary.
If you are using one of Apple's routers, run the Airport Utility app which is located inside the Utilities folder. If using a 3rd party one, read its user manual and/or contact their customer support department/website.

If using Apple's Airport, please re-post over in one of the AirPort Forums.

Macbook freezing, running slowly, and making strange noises

Hi. Just today my wife's MB froze while doing nothing more than playing music in iTunes. She had to leave so just closed the lid. When I opened the lid later, it came back from sleep eventually (playing the music), but was making an odd clicking noise. It sounded like it was coming from the upper right side under the keyboard. It didn't sound like the noises the optical drive usually makes, and there was no disc in it.
I left it charging, and when she came back to use it later, found that it was running really slow, taking forever to open applications (prolonged spinning pizza of death), and still making that strange noise. She restarted it twice, and the same thing occured after a reboot?
Any thoughts/suggestions? We have applecare, so we'll likely be giving them a call if it doesn't go away, but I like to check here first.

The same thing happened to my notebook last night, and I did some research. Apparently one of the reader arms in the harddrive separates from the drive and swings loose, digging gouges in the magnetic disk.
If it still boots, make sure you get all your un-backed-up information off of it before it crashes.
Mine is dead, and the only thing Apple can do is replace the drive.

My macbook (2009) keeps making strange noises. What to do?

Yesterday, my macbook started to make strange noises. A little scratchy noise. Like there's somthing wrong with the Fan or something.
I called Apple Support, but they told me i had to reset the SMC and PRAM/NVRAM. I triend, but the noise is still there.
Does anyone know what to do?? Is it bad?
Its a really annoying sound.

It could be the fan.....or the hard drive.....this is a link to a data recovery firm that has posted the various sounds made by failing hard drives.......

......make sure your data is backed now in case the hard drive is failing.....

2.8GHz 24" iMac Making Weird Noises

It started out sounding exactly like a cricket. When I first heard it, that's what I thought it was. It would start soft and grow louder, then softer again and fade out. Now the sound has the same pattern, but it's evolved into a full-fledged rattle/clicking sound and has a cyclical pulse to it. Hard to explain. It's fairly loud and VERY annoying. It happens every minute or two and lasts for about 20 seconds. Any ideas?
This is my 2nd Mac w/ problems immediately or very soon afterward...2 out of 2. Just lucky I guess, right?

Does the system run normally? Open up Disk Utility, select your drive on the left and look at the info listed at the bottom for SMART status. Also Verify the Disk.
It could be one of the fans making the noise. Possible rubbing up against something else inside. Either way you'll have to put a call in to Apple support to have it repaired.

Please help..Making one of two checkboxes reuired if another is checked.

I have googled to the end of the internet and cannot find the solution I am looking for. I am a noob to Javascript.
I am working on a Systems access form where a users manager selects what he/she wants his user to have access too. The form Validates itself before printing. Here's where i'm stumped.
I have a checkbox for Internet Access called "Checkbox1". Then beside it, I have 2 checkboxes. They are named checkbox2 and checkbox3.
here's what i'm trying to do.
If - "checkbox1" is checked
Then - Require either "checkbox2 or checkbox3" be checked before printing.
Else - Nothing is required. User can print form.
Please help.

Hi Joann123
That sure sounds like the Hard Drive accessing data, some are noisier than others.
For example: the original 160GB Seagate Barracuda that came in my Early 2006 Core Duo sounded about the same. After using it in the iMac for 3 years I took it out and put it into an External drive, another year later it still sounds the same but works just fine as an extra backup drive for my music and photos.
I don't think that it is going to fail tomorrow, but if it really bothers you that much backup to be safe and by all means contact Apple as explained by those that have replied in your other thread.

I need help with my iPod. It's making strange noises. Can I get some help?

I just got this brand new 160gb from the Apple Store. When I got home, I put all of my music and tv shows on it. When I started to use it, it started to make a buzzing noise, then a clicking noise, and then a noise that sounds like "pewwww" like it's powering down.
I was wondering if putting all that music and stuff on was too fast too soon. The "Genius" at the Apple store said it was a problem with the hard drive.
Thank you in advance.

I believe them. I was just wondering if the noises are something that will eventually go away with use. Something else I wanted to know is if putting ALL my music and other media on the iPod at one time is what did it.

Mac Mini making strange noises through external speakers

I am experiencing a strange problem with my mac mini and my external speakers. I have two different sets of speakers and the problem occurs with both so I don't think its the speakers as I have never had any problems with them on my other computers. The Mini will make strange gurgling and hissing noises through the speakers at seemingly idle cpu times. Under heavy loads I get the gurgle occasionally but it seems more prevalent at idle times. After playing around with it I have noticed a direct correlation with my wireless connection and the noise. If the mini drops the network, which it does from time to time, I get the noises but if I disable airport then they stop. Have any other mini users experienced this? It's harmless but rather annoying because my mini is set up in my dorm room and we often have music playing and when I go to sleep I hear these weird noises.
Thanks for the feedback in advance.

The Airport sub-system in the mini is identical to any other Airport Extreme equipped Mac, with the addition of a riser board on which the AE card is mounted, and which no other Mac has.
If the mini suffered a design flaw in Airport implementation, then everyone would be hearing the same sound. Neither AE-eqipped minis I've got in my system exhibit any sign of it.
RF interference can get into an audio system in a number of ways - most commonly by direct injection (ie, something in the audio circuit such as a circuit board track or speaker wire) acting as an antenna and picking up an unwanted signal, or by FR breakthrough into the power circuit - usually through the transformer or rectifiers. In the first instance, a change in channel would change the transmission frequency and thus the sensitivity of the component to the signal (thus usually making it stop altogether) and in the second, would usually require a transmission power of significantly higher level than the few milliwatts used by Airport.
There are other possible causes too of course. Even a cordless phone in the same vicinity is capable of generating RF interference - but then stories of people listening to radio stations breaking through into phone lines, and even when opening oven doors are legion - and often true.
In the case of an Airport network, where the user has control over transmission power levels and frequency, a bit of tinkering with the two can resolve many FR interference issues. Incidentally, if you're interested (given your general technical background) a number of very informative sources on RFI (Radio Frequency Interference) are published for and by the amateur radio fraternity.
