24" iMac, two beeps at startup. Anything to check besides RAM?

One of our 24" iMacs has done the "two beep gray screen" twice in its 3 week long use. The first time was during one of the reboots on the first day, the second time was today (a few weeks apart).
The day it arrived I put in a stick of 1G ram, and I know it's the correct speed/type. I was also grounded during the install so that's not the issue (I hope). I've run the startup diagnostics and it didn't show anything wrong with the memory.
I may try and re-seat the RAM, but the iMac doesn't do the beeps often, just those two times. The machine has also been VERY stable and fast.
Is there anything else I should try before returning the memory or calling AppleCare?
Thanks!
-Sean

That's exactly what I was planning on doing. Thanks Dave! Hopefully it's that easy to diagnose/fix.
All of the issues people have been having with various components of the 24" iMacs has me very nervous. Thankfully we have a 3 year AppleCare warranty, though that doesn't shorten the machine downtime.
*fingers crossed* I hope it's just the ram.
Anyone else have any thoughts?

K9A2 CF-F two beeps at startup

Greetings, I just finished building my computer and when I finally booted it up it did it's things and proceeded to beep 2 short times.
According to the AMI Bios codes it means that there's a parity error (I do not fully understand what a parity error means). I have tried reseating the ram sticks without luck, no matter how i position them I still get the two beeps, I also came across my old DDR2 PC4300 ram sticks which is the slowest ram the motherboard could handle.
I decided to try removing the new ram and installing one of the old sticks, the machine sucessfully booted but then proceeded to beep twice.
I've tried everything I know and it just won't seem to go away. The weird thing however is that, if I boot into Ubuntu, I cannot notice that there's any problems with the ram, its working swimmingly so far.

Thanks a lot. It seems like it does actually count the number of usb devices. I tried adding 4 usb devices and it did indeed beep four times

IMac sometimes beeps endlessly after wakeup

I'm not very familiar with Mac computers, though I'm very experienced with Windows computers, so I might overlook or misunderstand things obvious to someone more familiar with Macs. I'm helping a less technically-oriented friend with her Mac. I'm not sure I have all the information that is needed, but let's try.
The computer is a fairly old one-piece iMac. The "About" choice under the Apple menu says it is an iMac 5,1 and SMC version (system) 1.8f2. The current OS is 10.6.8. I believe the original OS was one of the 10.4 versions. The computer originally used a wireless keyboard and wireless mouse, both from Apple. Sometime after the upgrade from 10.4.x to 10.6.8, the wireless keyboard and mouse were replaced by a wired keyboard and mouse. There is an HP inkjet printer connected to the computer. The owner of the computer is not certain of the timing, but believes the beeping that is the subject of this post started after the switch to the wired keyboard and mouse, but she admits that it might have started before the switch. She is confident that it started sometime after upgrading to OS 10.6.8. She was told by the staff at an Apple Store that she needed to upgrade to OS 10.6 in order to use Skype, or some new version of Skype (I am not sure about that reason).
The problem is that, at times, the computer will emit one beep or a series of beeps (the owner sometimes calls them clicks, but I have heard them and would use the word "beep"). The owner has reported only one situation in which a single beep occurs. Usually, it is a repeating series of beeps, each of the same duration (about half a second or maybe a little less, I'd say) and with a uniform interval between them, though I can't say whether the interval between the beeps is the same as the duration of each beep.
The beeping usually starts immediately after the computer wakes up from the sleep state (done by pressing a key on the keyboard). The owner usually puts the computer into the sleep state when she is done working for a while by selecting Sleep from the menu. I imagine it sometimes goes to sleep on its own due to exceeding the configured time of inactivity, but I have not asked her that. Sometimes the beeping does not start immediately after wakeup, but when a folder on the desktop is opened. When the computer is emitting a series of beeps, the beeps usually can be stopped by opening Safari and starting to type a URL. Typing the first letter of the URL stops the beeping. The owner is not sure whether starting any other program also can stop the beeping. If the beeping started when a folder was opened, usually closing the folder makes the beeping stop. The owner says that she thinks opening a folder containing Word files causes the beeping (though that does not trigger beeping all of the time), but most of her folders contain Word files, so I'm not sure it actually is necessary for there to be Word files in the folder to trigger the problem.
When the computer is emitting the series of beeps, the owner reports that the menus respond differently than normally. She says that, normally, when she clicks on a menu, it stays open while she makes her selection from it, but when the computer is beeping, she must hold the mouse button down while selecting her choice, else the menu will close.
The beeping does not start after every wakeup, but once it has started beeping after a wakeup, the beeping starts at all subsequent wakeups until the computer is shutdown. The owner does not know whether a restart rather than a shutdown also stops the beeping after wakeup. When beeping occurs after a wakeup and has been stopped by starting Safari, the owner believes that the computer does not resume beeping again until it has been put to sleep and is awakened again.
The owner has not had the computer start beeping right after being turned on, however, it sometimes does emit a single beep when the first letter of the user's password is entered into the logon dialog box. This single beep did not occur on a test of using the logon dialog after logging off without shutting down. (The owner does not usually log off, but I had her try it just as an experiment to see whether the single beep would occur when logging on in that situation.)
Possibly related is that there have been times when Word documents will not open. The owner mentioned that when this happens, if she hovers the pointer over the Word icon in the dock, she gets a choice to force quit. I believe she said that using the force quit restores normal operation of Word. There also has been at least one case in which Safari refused to close. I don't know how common this sort of stuck program is in a normally-operating Mac, and I don't know how often it occurs on this Mac.
When I was observing once, when I asked the owner to log off, the logon dialog box proceeded to shake rapidling left and right a small distance (perhaps a centimeter or so) while the computer emitted a series of beeps different from the other series of beeps I described. This series of beeps had two beeps in rapid succession, followed by a longer pause, two beeps in rapid succession, longer pause. This repeated until a key was pressed. The owner has seen that occur only that one time, but she does not normally logoff while leaving the computer running.
We have uninstalled and reinstalled Office (including all the updates to make it current). We have verified that Bluetooth is not enabled, that the old Bluetooth pairings have been deleted, and that the batteries have been removed from the wireless keyboard and mouse. We have reset the PRAM and the SMC. We have run the Apple Hardware Test and it found nothing to report. We have disconnected and reconnected all of the cables (keyboard, mouse, printer, ethernet). The problem of the endless beeping after wakeup sometimes still occurs.
I imagine the next logical thing to try is to reinstall Mac OS. The owner is a bit reluctant to try that. She does have copies of her personal files on CDs, but she is reluctant to undertake reinstalling the applications. Reinstalling the OS without erasing the hard disk probably would be less disruptive, but is there much chance that would eliminate the beeping? My guess is that something in the software somewhere has gotten messed up, and a completely clean installation would be the only way to guarantee to clear it up. Am I discounting the chances that just reinstalling the OS could fix it?
My feeling is that this is a software problem, not a flaky piece of hardware, but is that justified? If it might be a hardware problem, which part of the hardware might it be?
At one point, I had an idea that there is some software remnant of the wireless keyboard or mouse software still active that sometimes causes fake input that triggers the beeping. However, I don't know enough about the Mac to know whether that is a reasonably likely possibility, and, if it is, I don't know what to do about it.
All suggestions for clearing up this beeping problem will be accepted gratefully. Suggestions of other experiments to try also are welcome.
If we do decide to try a clean install of everything, should I first install the OS from the original discs that came with the computer, then upgrade using the OS 10.6 discs, or should I just start with the OS 10.6 discs?

Hello, excellent work so far!
It doesn't sound like this much, but including for pondering...
The following table lists the new tones and their meaning:
Tone(s)          Description
1 tone, a 5-second pause, repeat          No RAM installed
3 successive tones, a 5-second pause, 3 successive tones          RAM does not pass data integrity check
1 long tone when holding down the power button          Firmware upgrade in process. See About firmware updates for Intel-based Macs for more details.
3 long tones, 3 short tones, 3 long tones          Firmware restoration from CD in process. See About the Firmware Restoration CD (Intel-based Macs) for more details.

Can you count the beeps or flashes?
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable
In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.
Note: In this case, a flash is considered to be 1/4 second or 250 ms or greater in length.
It sounds more like some Hardware issue at the moment, but only by a slight margin.
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

Why is my iMac running slow at startup?

I shut down my computer about once a week or so, because I hear that's good for it. But when I start it back up, I might as well go make coffee. If I try using it, all I get are beach balls and HD noise, even though there's 12 GB RAM free during all this , and the CPU is barely using 4%. I suppose it's disk activity? Here's my results from EtreCheck below; I notice Carbonite is still on my system, even though I've removed it. Time Machine is not configured because I use SuperDuper and BackBlaze. The Mac HD is brand new; the last one failed and Apple replaced it.
Problem description:
Slow startup. 16 GB of RAM yet even during the slow startup, 12 GB are free. The CPU runs at 97% idle during the slow startup. What’s causing this?

P67A-GD55 - Two beeps after turning on the reboots loop

Hi
just installed a P67A-GD55 with a i5 2500k into my PC and everything was working fine, all drivers installed etc booted to Windows 7 no probs. Restarted and went into BIOS to check a few things then rebooted.
PC starts, two beeps, then reboots, continuously.
No BIOS LED flashing. So it seems two beeps means parity error. I've looked this up and mentions something about first 64k of mem check failed. To check RAM.
So went through each slot with one RAM and tried different RAM too to make sure, no difference. So booted up with no RAM in. No beeps but PC just starts then reboots in a loop.
Never got anything on the screen.
Checked all connections, removed all hard drives etc no difference, unplugged USB cables etc so in end just had graphics card, one stick of RAM, CPU and power plugged in. Still two beeps.
Reset CMOS still same, two beeps the reboot loop.
Tried all sticks of RAM in another motherboard and i5 760 and boots fine so its not the RAM.
Can't understand it as it worked fine at one point.
Is my motherboard faulty ?

Quote from: Mark on 01-June-11, 17:15:51
MSI is right. In the UK you need to get the product replaced through the retailer. You might need to phone Aria in this case.
I've filed an RMA request at the moment and told them what yourselves have said. Just need to wait now.
Didn't want to ring them just yet as there RMA number charges you 60p per minute.
I'll just have to wait and see what happens.

MBP Requires Two Attempts To Startup

My wife's MBP 2.4 GHz Core 2 Duo OS 10.5.8 takes two attempts to startup at least 50% of the time. She thinks that the problem started around six months ago. It stalls at the white startup screen. Clicking the power button turns it off and then it invariably works fine the second time the power button is clicked.
The MBP is not connected to any peripheral devices and I cannot associate the start of the problem with an update or software installation. The MBP is essentially identical to our 24" iMac in terms of installed programs and its configuration. The iMac occasionally has the same problem but it is much less frequent in nature, perhaps one out of every 50 times it is booted up.
I could use some help diagnosing the source of the problem. If it may be a hardware-related problem I would like to know because the extended AppleCare warranty is up in October.

I would just reinstall OS X as follows:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

G4 beeps on startup

I got a new HD and new 512MB stick of ram put into my G4. It seemed fine after the HD was installed but a few days later when I bought some second hand ram and slapped it in I got a faint beep on startup. I tried every combination of the ram, but couldn't get rid of the beep untill I unplugged the new HD. So I took it in to the Mac store where I got the HD installed and we couldn't hear the beep!! Took it home and it beeps again, but only when the new HD is plugged in. One strange thing is that the total ram only shows up as 1.19 when it should add up to 1216 MBs; that is two 512's, one 128, and one 64mb stick.
Any ideas?

Hi, Mike -
Welcome to Apple's Discussions.
One strange thing is that the total ram only shows up as 1.19 when it should add up to 1216 MBs; that is two 512's, one 128, and one 64mb stick.
1216MB is correct, and 1.19GB is correct. RAM math is a bit odd because it is base2. One GB = 1024MB, not 1000MB. So, 1216MB divided by 1024MB/GB yields 1.19GB.
Is it possible the drive itself is beeping? Some few have been known to do that, but when that happens it usually presages a drive failure - not something expected with a new drive.
Is the drive jumpered correctly? If your Mac is older than a G4 (MDD) model, you should not use Cable Select jumper settings.
There are some beeps at startup which can indicate RAM issues -
http://docs.info.apple.com/article.html?artnum=58442
However, those will replace the normal startup chime. That is, if you hear the normal startup chime and then the beeps, it's not a RAM issue.
At least one person posted a similar issue a few years ago. Careful listening finally traced it to the user's UPS - it was alerting that it was running on battery.

K9N6PGM2-V, No Audio, PCI error in Device Manager, beeps on startup

I've about had it with this board and its problems, but I thought that I'd give this one last shot before I try another board.
No sound from the mobo, but USB headphones work OK.
Athlon 64 X2 6000 3 GHz OEM Processor, Kingston 2048MB DDR2-667; all drivers and bios (9.3) updated; HD audio enabled in setup, XP Pro 32 bit; CPU running at 24 deg C. On startup there are two beeps that sound about the same length; one low pitch, then a high pitch. From the command prompt when I type mem, it says there is 1 gig of memory. In System Information it says there are 2 gigs. MSI is closed for the new year ... !
I'm also not thrilled about all the crap that was installed in the tray.
What shall I try next?
~ Dave

Do you have Sp3 installed?

T500 Beeping on Startup

One week ago, my computer (Lenovo ThinkPad T500) has started beeping upon startup (one long, two short) and will not allow the system to start. I have to shut down and restart a considerable amount of times before the display finally shows up. The odd thing is that it has informed me that this indicates a video problem, and yet I have run diagnostics and the such, and there is nothing wrong. Furthermore, my computer runs perfectly, if not even better than before the beeps started.
This problem is starting to get annoying and I'm afraid that I might irreversibly damage my computer if I keep trying to start it up when it is beeping. How can I fix this?
Thanks for all of your help!
Solved!
Go to Solution.

katrimc, welcome to the forum
according to the Hardware Maintainance Manual, (pdf p. 52), the beep code means that you possibly have a problem with either your System Board, Display or Memory. I suggest removing and reseating your memory, (pdf p. 78 or look here), and if the problem persists to run memtest86 to check your memory. Let it make at least 3 full passes.
If your memory passes and the symptoms still persist you should call support.
Let the forum know how you get on.

Two beeps and flashing screen

My wife's 3rd generation nano stopped working while she was listening to a podcast for runners. There was no response.
I tried resetting it, pressing the middle button and the top for over ten seconds. No apple logo but I heard two faint beeps.
I tried holding the middle and the down button. Two beeps and the screen flashed repeatedly.
I hooked it up to iTunes and it was recognized. I tried restoring the software. I renamed the iPod just to see if the connection was really there. After I reset it I disconnected and repeated the first steps with the same results. I hooked it back up to iTunes and it recognized the iPod and the new name.
I checked for update. No glory.
I'm at the end of my knowledge, any ideas?

the same exact thing happened to me yesterday. I was running and a song would stop halfway through it. I kept pushing play again and it got to be every 10 seconds instead of every minute or so.
I finally let it stay paused and my screen never worked during that time. I went home and plugged it in the computer and it didnt recognize it and the screen stayed blank. I restored the ipod to default settings from the computer and during the whole time the screen never came back on, just beeping, not even a flashing screen.
I was able to add songs back on it from my computer but it still doesnt work or anything, connected or disconnected from the computer. I left it alone all night plugged into the computer and it still wont work at all. It just beeps. Ive tried the resettings and all. PLEASE HELP!!
Thank you

Machine thinks RAM is incompatible (two beeps, loud fan, no video)

The Problem: computer will not boot, gives two beeps and fans run full blast. The status codes indicate not that the ram is bad, but that it is not compatible with my machine.
Background: My PowerMac G5 1.8 Single (Late 2004) has been collecting dust for the past two years, so I decided to make use of it and turn it into a media hub. I basically dismantled it and dusted all the parts (I know what I'm doing for the most part) and put it all back together. I wiped the hard drive before doing this so there is no OS installed.
Now when I turn on the computer, I hear two beeps, the fans go full blast, and no video. The power button LED blinks twice, pauses, then repeats until I turn off the computer. I am using the same RAM, so I know it is compatible.
I have tried resetting the SMU, taking the RAM out and replacing it, installing the ram it in every possible configuration (2 512 mb sticks and 4 slots), and ensured that it is in correctly. I can't install OS X because I cannot get picture, nor does the optical drive open.
The blinking power light indicates there is a problem with the ram, but my experience (experience of only upgrading RAM and NEVER needing to replace it) makes me want to look for other causes before I order some new RAM. I tried resetting the SMU, but I'm not convinced that it worked, especially since my model doesn't appear to have SMU or PMU reset buttons. Apple says to turn off the computer and unplug the power cord for two minutes instead.
I should also add that none of the status lights around the memory slots are lit up, but there is a solid red light coming from the top corner of the motherboard just above the expansion slots. I have yet to discover if this means anything.
Any suggestions would be greeaattly appreciated
Thanks,
Jack

Are you positive you've installed the two RAM sticks in the innermost slots of each bank of slots as shown in this article: http://support.apple.com/kb/HT2248

Mac Pro 8 Core 10.6.4 - 12 fast beeps at startup

Yes you read that right.
My Mac Pro 8 core is exhibiting some strange behavior (probably some kind of failure).
At Bootup the mac does its normal startup chime, then my attached speakers make a crackling noise, followed by 12 ( yes twelve) rapid tones, the speakers then crackle again and is followed by another 10 beeps. My MacPro then boots normally. All RAM is accounted for, RAM test in OS X and hardware test report no errors.
I have checked my RAM, re-seated it, did a four finger salute (PRAM) - Still beeping -
I have heard of the MacBoo Pro beeping 9 times, but it sounds nothing like this nor have I been able to find any other posts about it.
Trying to diagnose before I drag this 65Pound beast in for service.
I know what's wrong with 1, 2 ,3 ,4, or 5 beeps at startup

Dx2300, beep on startup

I bought a DX2300 microtower used. It worked beautifully at the sellers house. We removed the wires/cables and I took it home. When I reassembled everything I got no action on the monitors(dual), no lghts on the wireless keyboard nor mouse. The CPU makes a single, long beeping on startup. The only thing I did to it was clean out the dust from the front vents and fan units. I believe the seller had a 1T byte external harddrive, but other than that, II believe it's all the same. Any suggestions?
This question was solved.

I went inside and unplugged and reset each cable I could. It started up smooth and other than the black screen telling me it hadn't been shup down correctly - all works fine. I was able to get my wireless internet set up. All is well in my world. Thank you very much for the help.
