Won't start up, makes weird beep, power light flashes, and fan revs

I just tried to install new ram, but now it won't start up. I put the configuration back to what it was, but still not starting up. It makes a different beep then the fan gets really load, and the blue light flashes slowly...
ahhhh... did I break it?

Hi don rumsfeld-
Greetings and welcome to the Apple boards
Flashes described here: About the Power Mac G5 (Late 2005) diagnostic LEDs
My guess is that the RAM was either not installed properly or not seated firmly. This may be helpful: Memory (DIMMs)

TECRA 9100 - power light flashes and will not start up system

my laptop will not start up - all I get when I push power on button is the power LED flashing the following sequence. S-S-S-S-L-L-L-S(S=SHORT, L= LONG)
DOES ANYONE KNOW WHAT THIS CODE INDICATES.
The only thing I might have done was to put a screw (b8 which is 12mm) into the network card locking switch slot on bottom of laptop that says MAX 4mm .
Any info would be appreciated to [email protected]

Hello
Unfortunately here is no public document about explanation of those hexadecimal codes and I can not tell you what it means exactly. The fact is that power supply electronic has detects some malfunction and sends code.
Sorry but I dont believe that you can do something alone. Try please to contact service partner in your country and explain them the situation.

Three beeps then led flashes and fan is on

Hi. I haven't used my mac in a while and tried turning it on...it beeped three times then the led flashes three times and pauses, and the fan goes on full blast. I found out in my quest for answers that the 3 flashes could mean bad RAM. I have the factory installed RAM...I had some problem with my computer before and an apple tech put in a new logic board. Could this be the problem? I'd like to fix it myself since the tech is a hike away. Any thoughts? Thanks for the help.
PowerMac G5 2ghz Mac OS X (10.4.8)

Hi. Well -
Not sure whether you need the FW card for your recording session - but if you remove the FW card, and get the G5 up and stable first - then put back what you need and try it.
I would try to boot from the most recent system disc you have - presumably it came with 10.4 if you have a "Late 2005" dual-core 2GHz G5 with PCI-Express
http://support.apple.com/specs/powermac/PowerMac_G5_Late2005.html
- and Verify, or Repair if necessary, the startup disc
http://docs.info.apple.com/article.html?path=DiskUtility/10.5/en/duh1018.html
in case directory corruption has occurred during the various shutdowns and restarts.
If boot problems still persist, it may be worth re-seating the video card, also.
There are threads in the Forum mentioning that FW card
http://discussions.apple.com/search.jspa?objID=c108&search=Go&q=siig+NN-E20012-S 2
There is some discussion there of the power requirements of the connected firewire device - and of the possible need for a separate power connection to the card. It's also possible that the FW card needed re-seating, after the G5 not being used for a while.
It may also help to disconnect anything firewire - iSight, drives, etc. - not needed at this pressing moment...
Have presumed that you don't need Airport for tonight - but if it appears to causing problems with the basic startup, it can be disconnected; although this is more complicated on a dual-core, and to be avoided, if possible.
Anyway - trust some of this helps. Good Luck.

My MacBook Pro won't start it just goes beep beep beep when I press the power button

My MacBook Pro won't start it just goes beep beep beep when I press the power button

Hi Csound1,
I haven't added any RAM my daughter was using the computer then it hung so powered it down then the beeping started. Do you know if there is a combination of buttons I can press when powering up that will put me in some kind of safe mode so that I can find out what's up, I tried pressing D when the beeping started but it didn't make a difference.

27" iMac 3.2 i7 won't start. Emits 3 'beeps', pause, repeats.

My 27" iMac 3.2 i7, 20GB RAM won't start. Emits 3 beeps, pause, 3 beeps, pause.

Here's a link to an Apple support page that describes the possible Startup tones.
Mac computers: About startup tones - Apple Support
The short answer is here. Looks like your RAM is bad.
1 tone, repeating every 5 seconds: This indicates no RAM is installed.
3 successive tones, a 5 second pause (repeating): This indicates RAM does not pass a data integrity check.
1 long tone while holding down the power button: Indicates an EFI ROM update is in progress on a computer manufactured before 2012.
3 long tones, 3 short tones, 3 long tones: Indicates EFI ROM corruption is detected and the computer is in EFI ROM recovery mode.

My mac falls and don't start only makes a beep sound

please tell how i can fix my mac

Beeping noises, sometimes with the power light flashing, indicate "not enough Working RAM Memory to start up".
You need some known-good RAM to make progress.

PowerBook G4 - Won't Start Up - 3 Strange Beeps then just LED flashes and sudden death - black screen.

PowerBook G4 - Won't Start Up - 3 Strange Beeps then just LED flashes and sudden death - black screen.
Prior that the powerbook also couldn't start but I could see the Apple logo, so via fire-wire (holding T at start up) I backed up the hard disk.
Check via DiskToolPro the structure, defragmented. Via DiskWarrior rebuild the directory
and finally not been able to access the drive I reformatted the drive via fire-wire drive.
Re-started the powerbook holding C to boot up from DVD - nothing
Re-started again and it give me one long beep and black screen. An indication that my 1gig RAM is bad or gone (?) and the DVD is stuck inside.
Bought new one 1 gig, installed it and now I'm getting only three beeps.
I tried all, changed the slots several times and nothing.
I tried more as:
                         c -- to boot from CD (again while the DVD is still inside and I cannot get it out)
                         cmd-opt-p-r -- to Zap the PRAM,
                         cmd-opt-n-v -- to clear NV RAM,
                         cmd-opt-o-f -- to boot into open firmware … and nothing. The DVD is in and I have
                                                black screen with three beeps and flashing LED.
Do I have to replace the Logic Board?   (Anyone has a spare one ?)
But it is the faulty Logic board?
Could anyone help me out? Please.
I'm retired and I cannot afford a new laptop - and this powerbook was a great, great horse for me until that horrible set of three beeps.
Thank you in advance for any advice and help.

But it is the faulty Logic board?
There was a known issue with LBs in 15-inch PowerBooks with 1.5 and 1.67Ghz processors in which one RAM slot would fail. There once was a repair extension program that fixed the problem at no cost, but it is long-expired.
The problem with seeking a used logic board for these models is that so many had their boards replaced that it increases the chances of the boards in the used/pulled markets having the same problem you have now. The replacement program also came close to exhausting the supply of new boards,
If it turns out to be a bad LB and you can't find a replacement, consider how used computer pricing works: A used computer is worth hugely more in parts than if bought as a working unit. I.E, you can probably find a working PowerBook that will cost less than the logic bard alone. It also possible to find a used MacBook Pro for less that a replacement LB.
If you tell us your approximate geographic location, we can see what's available nearby. I'm also retired, and and visiting my wife's family this week so have even more time than usual to help you search.

I have a stuck CDR disk in my MacBook. I have tried everything and nothing works. When the computer starts it makes weird sounds and also when I try to eject it. Nothing Works! Please Help.

I have tried everything and nothing works. When the computer starts it makes weird sounds and also when I try to eject it. Nothing Works! Please Help.

I had that happen with a MacBook. It turned out that the metal case above the slot was slightly bent down.
Putting a flat blade screwdriver in the slot and gently twisting it to move the metal case up allowed it to eject. Don't put it in too far you only want to bend the case not the drive.
The case can get bent down by picking it up with your thumb pressing down on the case above the slot.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Trying to turn on my HP compaq d330 but red light flashing and beeping and nothing comes on

trying to turn on my HP compaq d330 but red light flashing and beeping and nothing comes on help a newbie please
This question was solved.
View Solution.

You can try removing and reseating the memory and see if that works.
If that doesn't work, remove all but one memory module (if the PC has more than one), and see if the PC runs normally with one memory chip. If it beeps, remove and replace with the memory you removed and keep doing that until you find the bad memory chip.

My BB won't turn on the red light flashes and the key's light up

Hi
I have read all posts relating to my problem, but one thing my BB won't do is resgister on my computer. The phone will not turn on, has the red light flashing and the keys light up, but the screen will not come on. I have tried taking the battery out, charging it all night, all the recommended/ideas from this sight, but no joy. I have only had this phone since July last year. I haven't been able to try updating phone etc as it won't register on my or my husbands computer please help
Louise

Hi,
The way you presented it made me think it had just happened.
So you have had the phone since July has it ever worked?
Most likely you are missing some or all of your device OS and you'll need to reload the device.
Because the phone can't generate enough signal you will have to "force detect it". I've attached the link below. If you want to proceed I'll need what version of Device OS and what version of desktop manager software.
Thanks,

Power Mac G5 - Won't start up with the beep noise.

Hi all,
I am wondering if someone can help me with my problem. I've just gone to turn on my G5 after dusting out the inside (i unplugged the power supply and then lightly dusted the inside) and now it won't turn on.
The power light comes on, but there is no beep, and the fans start, but they gradually get louder. The white power light then flashes once in a while
Can anyone offer any help please?
thanks
Mark

Well - as long as you have pressed the button firmly once, that should be it.
I did wonder if you had disturbed the RAM while you were rummaging inside - is there a pattern to the flashes of the white power light, as described at the bottom of the page here
http://docs.info.apple.com/article.html?artnum=302527
If not, as the mains power has been disconnected, it's just possible that the internal back-up battery may need replacing

HP desktop won't start, red light flashing and beeping, loud fan

Yesterday it was working just fine. I turned it off for the night and when I tried to turn it on this morning, a red light was flashing and beeping as well as the fan making a loud humming noise. I've read the the beeping and flashing means something. I didn't keep track of the number of flashes and beeps though. After the beeping and flashing I turned the computer off then back on. This time there was no red light, flashing, or beeping. Nothing appeared on the monitor either. After about 10-20 seconds of it being on, the fan started to hum really loudly again.
It's an HP Compaq dc7900. I've only had it for about 3 months and it was fine up until now.
Any help? Thanks.

Hi
I'v checked the specs for your HP and Acer machines and yes it will be fine to cross over RAM modules they are identical in speed and architecture . Please don't forget the last post about removing the sources of power before you go inside the PC to check RAM . Other thing is if your HP has more than one RAM module remove only one stick first and try to boot . If it still won't boot with that module take that one out and try to boot from the other before you look to swap over modules from Acer machine . Don't forget to re connect your monitor to see if you get display with one / two etc modules . Post me back your findings

My iMac won't start...just beeps. What do I do now?

My iMac won't start up anymore. When I hold down the power button for 3 seconds and then let go al it does is beeps 3 times and then pauses for about 4-5 sec. , the 3 beeps and pause, and so on. Everything was working fine. I shut down the computer and now can't geitback on. Is it ruined?

Three beeps at startup indicates bad or loose RAM.
You can look up videos on how to replace RAM on your model Mac, at YouTube, or Other World Computing.
