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.

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.

Grey Screen at start-up - Troubleshoot harddrive and/or logic board?

Hi everyone. Sorry for the lengthy post, but hopefully you can help me - I've spent a lot of time on the boards already, but hoped you could clarify some things.
The problem is my Powerbook will not get past the grey screen at start-up. It will not boot off the 10.5 install disk and I can't eject the install disk to run the hardware test disk. Removing 3rd party ram, resetting PRAM, NVRAM, attempting to boot in 'safe' mode haven't helped. The harddrive is softly clicking/searching.
So some questions:
1) Is it possible that an interrupted time machine backup will bork the drive to the point where it wont boot? (See back-story below). I wouldn't have thought so, but prove me wrong.
2) Should I be able to boot from the install disk if the harddrive is stuffed?
3) If it is hardware, it's either the logic board or the drive. Is there any way to determine what it is (eg: is it possible to do a remote hardware test?)
Edit: Just tried mounting the drive in target disk mode using an iBook, but it wouldn't mount. Powerbook displays a black screen.
Oh, and I should point out that this is well out of warranty and any fixes would have to be cheap : ). Basically I need to determine if it's the drive or the logic board, preferably without having to buy and install a new drive when it may not be the problem.
Any help or advice would be appreciated.
Cheers
- Ben
Here's the back story if it's any help; recently upgraded to 10.5, created a base install disk image of all installed and registered apps (in the event that my drive failed). Copied data etc from the previous system over. It ran fine for a few days. This morning I ran time machine for the first time, left the computer for a while, came back and the screen was black (as if it was just displaying black, as opposed to off). Thinking it was just a display issue (which I've seen before), I put the system to sleep (power button, then 's'), woke it up again; still black. So I forced a shut down (wouldn't allow me to do a normal shut down, because dialogue boxes must have been preventing it) and on boot I got the grey screen.

Hi Ben W. I don't have a good answer for you, but based on your information and what you've done, I think I would try starting the machine after disconnecting the harddrive. That requires taking the top off first, for which instructions are on ifixit.com.
I can conjecture that a blown HD is preventing normal operation, perhaps sucking the power down, disrupting the optical drive, etc. This is purely conjecture, but costs you nothing but your time. If this turns out to be the case, I figure the optical drive should start responding again (hold C key during reboot, etc).

My old MBP (2005) often crashes, freezes or shows grey screen at start up. Also track pad often does not work. I have re fomatted the HD and reinstalled system but to no avail. Genius bar says possible faulty HD, but suspect logic board, any ides any body

My old 17" MBP (2005) often crashes, freezes or shows grey screen at start up. Also track pad often does not work. I have re fomatted the HD and reinstalled system but to no avail. Genius bar says possible faulty HD, but I suspect logic board. All checks out OK on the Apple Diagnostic bench. Can a Logic board go intermittant?? Any Ideas any body??

Ive repaired 1000s of laptops over the years (translate: diagnose and replace parts).
Its not that old, Ive owned 100s of laptops (most were free) ....some I still have are nearly 13 years old and still perfect, ....some extremely expensive ones died in under a year.
other than becoming obsolete at some point, there isnt really any "will spoil on" data like Milk for solid state computer parts, ....alas.
You can have a $5000 laptop die in 4 months, and a junker one keep kicking after 10 years.... Ive seen that firsthand countless times.
Common logic dictates that "very expensive = long life" in computers,..... but all the repair people will tell you just the opposite.
I know you have a gripe, I get that all too well honestly .

I'm getting the grey screen during start up and can't boot the computer. I did a cmnd R but worried it would automatically wipe my hard drive and reinstall OS. Is there a risk at cmnd R will result in wiped HD without me actively making that choice?

I'm getting the grey screen during start up and can't boot the computer - MacBook Pro with lion.
I did a command r after doing some research but got nervous that it would automatically wipe my hard drive and reinstall OS.
I was nervous because it asked me for language for software use before any options were presented (such as repair via disk utility). It looked similar to an OS install.So I powered off....Is there a risk at command r will result in wiped HD without me actively making that choice?

Repair the Hard Drive and Permissions - Mavericks, Lion/Mountain Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. 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 then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
Reinstall Mountain Lion or Mavericks

Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is
three times faster than wireless.

See this Apple note on steps to take.

Imac have grey screen at start up.

Have grey screen at start with question mark in folder. Have reset PRAM. Have tried start from disk and can not. Need help.

Your drive is shot, time for a new one. The question mark means the computer can't find a drive to boot from. If you have an external clone, you could try booting from that.

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.

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.

New iPhone 5c keeps beeping and the screen just stays black.

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
