Intermittent double beep and grey screen on startup

I just installed new third party RAM for my iMac (2008), because it was on sale. The initial RAM they sent me caused a kernel panic (forced shutdown) so I assumed they were faulty and sent them back. I just received my second set of RAM modules - which appear to work -- kind of. I have not had the kernel panic screen and no problems once the computer is booted, however about every second or third time I restart the computer I get the grey screen and a series of double beeps (which I have found out means incompatible RAM on startup testing). The hardware testing utility on my OSX Disc tests the RAM as being OK. I found a free app called rember which reports RAM errors. My question is: have I got a second set of faulty RAM - should I be looking at getting another brand (the one I have is "Add-On" and was specifically marketed as being for the aluminum intel based iMacs).
Thanks in advance,

Hi Machaon42
Welcome to Apple Discussions
That sounds like incorrect or incompatible RAM, double check the spec's of that RAM compared to either your User's Guide or > http://support.apple.com/kb/HT1760
Then compare OWC's price, it is iMac tested and highly recommended by forum members.

Beeping and Grey Screen on Start Up

Hi,
My iMac 2007, shut itself off and then restarted. At restart it gave the inicial apple "ping" then got a grey/white blank screen and started to beeb intermittently (tree beeps - pause - three beeps - pause - three beeps - etc).
I tried to turn off and on but when turned on there was no change.
I read in another forum that this represents a RAM incompatibility, but i have made no change to any piece of hardware since bought.
Thanks,
Yolanda

It can be failed RAM, unseated RAM or incorrect RAM.
The easiest way to fix it is to replace the RAM. The instructions are in your manual, if you no longer have you manual click the Support link in the upper right of this screen and navigate to the Manuals area.
We don't know which iMac you have so we don't know how much RAM you currently have or how many DIMMS.
The good news is replacing RAM is extremely easy to do.

Mac mini and grey screen at startup

ok, so last night we come home and my mom tries to turn on her mac mini, but it just freezes on the grey screen in the startup process. i tried booting from the disk but it didnt work (no the disk is stuck in the drive cuz i cant start up the computer to eject it) i tried booting into a version of osx on my external hd by holding down option at startup, but nothing showed up not even the internal hd. none of the startup commands work (firewire target,single user,safe mode, holding mouse to eject cd) none of those worked, any ideas?

First off, why can't you insert the original install
DVD that came with your mini?
The drive won't take the disk at all. I tried other disks as well, and it won't take any of them in either. The drive is pretty much non-responsive.
Secondly, if you leave the mini on the grey screen,
what happens? Does it keep going however long you
leave it, or does it show a flashing questions mark
after maybe 15 minutes?
It remains on the gray screen for however long I leave it on.
Thirdly, since the mini was running for a couple of
days after the 10.4.8 update, the problem seems
unlikely to have been caused by that. What were you
doing the last time the mini was in use? How did you
shut it down?
Browsing the web, email, and listening to music for the most part. I put it to sleep for the night, and then when I came back the next day to activate it, it froze on me. Pointer wouldn't move, it was locked up. First time that has ever happened to me. After that I ended up turning it off by holding the power button down for five seconds. When I turned it back on, I got the gray screen.
Fourthly, what model of mac mini is it?
It's the original basic model. 1.25 G4 processor, 40 GB hard drive, and 256 MB RAM.
Mac Mini Mac OS X (10.4.8)

Kernel panics and grey screen on startup

Hello savvy bunch,
I recently acquired a wonderful little Core Solo mini. My plan was to
run it starting up from a 400GB hard drive in an external FW enclosure
that has another 200GB drive I was going to use for backups. Long
story short, the 400GB drive starting giving me weird Finder problems
and such. Booting from the internal HDD in the mini fixed everything.
Then it started having sudden kernel panics at random moments (I could
be writing an email, browsing on Safari, whatever), after which upon
restart I get an empty grey screen that lasted forever. I tried
several fixes, and the only one that worked was unplugging the FW
enclosure. I erased and fixed both external HDDs, and things calmed
down for a while, but I just had another kernel panic-grey screen
episode, which I solved turning off the FW enclosure.
I remember now that I had similar problems before with the same
enclosure/HDDs and my Quicksilver. Could the problem be the enclosure,
or the hard drives themselves?
TIA,

Oh, don't worry, I know and use all the right protocols for mounting and unmounting FW drives. They only get turned off AFTER they are dismounted. Of course now I realize that you wouldn't think so the way I described what I was doing. (That was some lazy writing, I guess.) I also have several external drives in use with several other computers. It's this particular enclosure that seems to be trouble.
As far as brands go, this is some kind of generic two-drive enclosure I got from OWC on a big sale a while back. I cannot find a brand name for the life of me (and I have looked all over it). I have not had a lot of luck with two-drive enclosures. This is my second (the first one was I think a Newertech or some other OWC brand, which died very quickly on me. The HDDs survived and are still in use.)
As for Lacies, Smokerz, you are completely right. My first FW enclosure ever was a Lacie, and it's still going strong. I have my eye on a Lacie 1TB enclosure that's in Newegg for $99...

Repeatedly getting stuck on spinning wheel and grey screen, even after multiple re-installs of the OS

Ok, so running Lion on a MacBook, (2010 i think) and the OS got corrupted(stuck on spinning wheel and grey screen on boot)
Tried to repair the disk via disk utility using an install CD, no go, couldn't repair, so, did a clean install.
New install went fine, computer worked for about 3 days and then stuck on the spinning wheel again.
suspecting physical damage to the harddrive, I installed the OS to an external, and booted from there. Worked for a couple days and then stuck on the spinning wheel.
I have repeated the process 5 times now, each time it works for a little and then craps out again.
What's going on?
as a note, when I say it gets stuck on the spinning wheel, I have left it for 12 hours trying to boot to no avail.

The Apple Hardware Test doesn't always detect all errors.
Next time you get the gray screen/spinning wheel, try booting into the Safe Mode to see if it will boot.
Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart. For each disable/delete, you will need to restart if you don't do them all at once.

TS2570 Grey screen on startup...

I am using 2008 White Macbook with OSX lion running on it. Recently I tried to update the OS and then I started getting a folder with question mark on startup. After that I started getting a continuous grey screen on startup. I tried various options like command + option + P + Q, then Command + R, etc. but did not get any response. After that I pressed option key on startup then there was a response. A lock icon appeared on screen asking for a password. I tried the MacBook password and it is not taking that password as well. I tired all the passwords I remembered but nothing worked. My cd drive is not working and also I do not have original OS disks with me now. The apple service centre told that they can resolbe it as it is a vintage model. I called apple care but they are asking 29 $ for a call Which is ridiculou. Pl. help me

Does the lock screen look like the one on this page…
http://osxdaily.com/2014/01/06/set-firmware-password-mac/
That is an EFI password - it stops the firmware accepting ANY startup commands so you cannot boot from other media or use the startup keys to get into recovery mode, single user mode, target disk mode etc.
If you can't remember the password you will need to remove the battery & leave it unpowered for a few days. If you are lucky it will reset. If it doesn't reset you need to open the case & remove the internal clock battery. Not something anyone should do without the skills to work on electronics - take it to an Apple Store or an Apple approved service centre would be my advice.
It is also possible that you have Filevault password instead of an EFI password - did you need to enter a password after every reboot before the OS failed. This shouldn't be confused with a normal user account password.
If you have Filevault enabled you can still try booting into recovery mode, but you must enter the password to repair the boot disk.
The 'question mark folder' means it cannot find an OS that is bootable - it need to be repaired but you can't get to recovery mode without the EFI password - a catch 22 situation.
Since you have no install disks or other ways to boot it seems you are probably not going to be able to fix this. If you have another Mac you could try to download 10.7 & create a USB install disk & use that to try to repair the Mac, but it seems unlikely since it appears to have a firmware password.

M58p at start-up double beep, no post screen, no splash

Hi there,
Yesterday my Avast antivurus crashed, which itself was very unusual. I have run a quick check and found a few trojans, which names I have forget regrettably.
I've scheduled a deep scan at the boot, reboot and left for work. Upon return I found the computer with a black screen, impossible to restart.
At the boot one can only hear cpu and chassis fan tests, then a double beep and then nothing. No post screen nor splash screens. Can't enter BIOS settings.
The monitor is OK. I've reset the CMOS and battery, to no avail. One by one I have removed all peripherals trying to boot at each step, but the outcome was consistently null.
Dealing with such symptoms I would normally assume the motherboard is good to go to the bin, but the specific circumstances - trojans and all this stuff - make me think twice. Could some trojan or other malware put me in such a mess? If so, what to do next?

Trojans shouldn't affect booting. I hear two beeps out of an M58 and I immediately reset the memory. M58s are sensitive to the memory sticks being jossled out of position. Completely remove your memory and re-seat the sticks in the same slots. Did that do the trick??

T60 exhibiting 1 long and 2 short beep and black screen

Hello all,
i own a thinkpad t60 with ATI radeon x1300 graphics card. I read through your complete "T61p exhibiting 1 long and 2 short beep and black screen" thread and I have the same beep problem with my t60. Let me briefly explain you how the beeps occur in my system:
My t60 had this problem after I initally formatted my system and this 1 long and 2 short beeps used started occuring. But the strangest fact is that after those beeps and blank screen, the power light in the indicator light group is on along with battery and ac power lights. But then when I repeatedly switched on and off the system, the sequence of beeps dont occur all the time. Then I completely switched off the system and when I booted the next times I started pressing the ESC keys after pressing the on button. Most of the times ( 8 out of 10 times), the first 4 times it produced the same beep codes but after the 5th time, the system turns on. All those 5 times, I kept on pressing the ESC key once I powered on the system.
Also, every time I'd a chance I did run the pc doctor to find any pro blem with the board or video card, but every time it turned out to be fine. So now,every time I turn my system off or use a stanby/hibernate whichever turns the screeen off, on immediate reboot it comes out blank but with the power indicator light on.
Here by I also list any changes that I'd made:
1. I reformatted the system and only then this started to occur.
2. after reformatting lsat time, I forgot to change the boot sequence but now I;d fixed that by pressing F9 under startup in bios.
3. I'd also once replaced my RAM with a different one (have 4gb now, but I suppose t60 can support a max of 3gb). WIll this be a problem?
4. And in the recent times due to the ati3duag.dll BSOD has occured. Any idea what this error might be due to?
5. Due to all these uncertainities, I havent updated tot he latest ATI driver which is 8.593 * and I still have the 8.293* . Will updating to the new one be a problem?
I appreciate any help or guidance you can give me in this matter and I badly need to fix it for my projects.
Thanks
Vishak

I think your best way of diagnosing this is to remove the new ram and install only one chip, if the problem persists, try the other. If the problem persists, then I'd try booting from a Linux LiveCD (any will do but I'd recommend ubuntu.com). boot with the option to not change anything on your PC. If you get this same problem when booting linux, then you know it's a hardware problem, in which case I'd remove as much hardware as possible, drives, cards, etc... if it still persists, then you most likely have a bad system board. In this unfortunate event your best option would be a used one. A new one would cost more then the laptop is worth, but used T60 boards are pretty reasonable, I just found one for another member and could probably help you find one to if necessary, but lets hope it's just a ram chip. And by the way, your system is limited to 3GB, but in the chipset, and in your 32bit OS they came installed with. You can install 4GB, but it won't be able to use it all.

riyazfrombangalore,
your 13-inch Mid 2009 MacBook Pro requires 1066 MHz RAM, but you have 1333 MHz RAM installed. Try replacing the 1333 MHz RAM with 1066 MHz RAM — Macs can be picky about the RAM which they find acceptable.

new iPhone 5c keeps beeping and the screen just stays black?

Plug your device into the original charger & block in a wall outlet and leave it alone for a couple of hours. Then, while it is still plugged in, restart it by holding down the home button and the power button for 10-15 seconds until you see the Apple, then let go.

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

Beeps at startup are an indication that there is not enough working RAM DIMMs to start up.

HELP!!! intermittent boot failures - grey screen at startup

For the past six to eight months now I have been dealing with intermittent issues upon startup. My early 2006 Intel iMac will occasionally hang at the grey screen without the Apple logo showing up. No rainbow pinwheel, no nothing. Just a grey screen. The only option I have is to power off the iMac and then restart it.
When I first called Apple Care I was told that this was more than likely an issue with 3rd party software and that I should perform a clean reinstall. I followed the advice but still experienced the intermittent issues.
Lately, it got so annoying that I called Apple Care again and they set me up to take my iMac into the local Apple store for repairs. After five days without my iMac, I called the Apple Store today and was told that after 1000s of reboots they were unable to reproduce the issue.
That in of itself surprises me, especially considering last Friday I backed up, zeroed the drive and re-installed Tiger in preparation to taking the iMac into the store on Saturday and the issue re-occured twice with in 30 minutes of the initial reboot following the re-install.
Has anyone experienced this? How did you solve this?
I have found the following discussion but have yet to receive a response to my inquiry.

I have also seen posts on the net for similar issues, but those state that people have external drives connected and turned on. That doesn't apply in my case even though I have external drives. (They are normally powered off.)
2 Ghz Intel Core Duo MacBook Pro - 2 GB RAM Mac OS X (10.4.9) Original 5GB iPod, Pepsi iTunes 6GB iPod Mini, Black 8GB iPod Nano

Well, after six days of being at the Apple Store, my iMac finally has found its way home without being repaired. The techs at the store were unable to reproduce the issue.
In the process of the repair, techs at the Apple Store installed an Apple-created app called RestartX, version 2.5(1). They used to the app they stated to restart the iMac over 1500 times without being able to reproduce the issue. They left the app on the computer for me to try with my set up of Apple Bluetooth Keyboard, MS Wireless Optical Mouse 2.0, USB hub and Epson CX4200, as well as external hard drives.
Well I didn't get as far as the external drives when the computer did the same thing upon boot try 17 after the Epson drivers install on boot 14, boot 15 with the printer on and boot 16 with the printer off.
Now the computer is failing to shutdown properly when using RestartX. If there are any Apple experts out there this is the last log entry before the computer hangs and needs to be powered down manually.

Any help would be much appreciated. Looks like I will be heading to the Apple Store again tomorrow.

I have a grey screen at startup and cannot go any farther.

Hello,
My problem is similar to other folks problems. At startup I first experienced a flashing file folder with a question mark. After I tried to shut down and reboot I experienced a grey screen. After another shutdown and reboot I experienced an apple symbol with a spinning sphere below. I rebooted again after several minutes of watching this and no action. Now, I just recieve a grey screen.
I have tried some of the support tips with no success. Can anyone assist in walking me through a sure fire method(s) of getting my macbookpro up and running again.
I'm running on snow leopard. Macbook pro circa 2006..
Thanks

Here's a great Apple doc. on the subject.
