Macbook Pro beeping 3 times

Macbook is behaving erratically.
Most of the time it beeps 3 times, I have tried re-seating the ram, and switching it around. Keeps doing the same thing.
Occasionally I have actually got it to boot into the OS, after a period of time it just restarts.
I have also tried reformatting the HD, seem to work and booted into the OS and then the same problems started up again.
I have also got this screen shot:

I have also tried resetting the PRAM

    Hmm. The problem still may be the RAM - Apple buys the RAM it puts in its machines from third-party vendors (usually Hynix) so it could be a RAM problem.
    There are a couple of things that you can do yourself before taking your machine into an Apple Store or an AASP... download and run an application named Rember that will run a RAM test for you - let it run for a couple of hours or even overnight. If it turns out that your RAM is faulty, Rember will let you know. If it is faulty, then you have a couple of options - replace the RAM yourself or (particularly if you're under warranty still) take the machine to an Apple Store or AASP and have them replace the RAM.
    If Rember finds no fault with the RAM, then you'll need to take it into an Apple Store/AASP and get a free diagnosis on the machine. Three beeps do usually indicate faulty RAM, but if it tests good with Rember you likely have another problem - it could be something as simple as the RAM, somehow, not seated correctly or signs of another hardware problem.
    Run Rember first... call back with results.
    Good luck,

  • Can't backup macbook pro to time capsule

    I have backed up IMAC to my time capsule no problems but when trying to back up my macbook pro it wont do it. The macbook pro sees the time capsule but once time machine commences you get error mesage advising problem encountered as macbook pro and time capsule not on same network?
    Any ideas?

    Are you connected to the TC by wireless?
    Are you running Lion? Try using ethernet and turn off wireless.. what happens??

    I have chosen to fil migrate from old ibook to new MacBook Pro using Time Machine after establishing admin account. I now have two admin. accounts and wish to delete the later one and transfer files manually. I am worried I will loose both accounts. ??

    Use the Office for Mac and ignore using Parallels for that. If you have PC only apps you have to run that are MS Windows only then consider Parallels. Just transfer your main PC, using Migration Assistant.  If you don't know how then simply read over Pondini's article called Lion or Mountain Lion Setup Assistant tips and look for the section on migrating from a PC. Millions have done what you are about to, it's far from leading edge these days, if you go to an Apple Store to purchase they will offer this as a service, something you might be interested in.

    There is something wrong with the volumes buttons in my macbook pro, every time i pressed the one who raises the volume, it leads me to the screen where (i do not no what its called) the background is black with the date and time and a calculator. However, when i lower it, my safari tab goes out of the screen. What do you guys think i should do? I'm getting very nervous.

  • MacBook Pro and Time Capsule after adding new wireless router

    I have a MacBook Pro and Time Capsule (which functions wirelessly to router and computer). I added a new wireless router (netgear, not my idea) and had to change name of wireless network. Now Time Capsule flashes amber and does not show up in Airport Utility.
    Do I have to set up Time Capsule from scratch? If so, if you can aim me to directions I won't have to waste tech support's time.
    My additional question on a similar vein: I also have a Time Capsule (second time capsule) which is plugged into the wireless router using ethernet cable for use with a windows notebook running windows 7 which backs up wirelessly. Do I have to change anything on this Time Capsule (second Time Capsule) as a result of change in name of network (I've already adjusted computer to connect to network)?

    Hi DD,
    If you don't get answers here, try posting in the Time Capsule forum (http://discussions.apple.com/forum.jspa?forumID=1253) and/or the Time Machine forum (http://discussions.apple.com/forum.jspa?forumID=1342).

    ow do I restore my MacBook Pro from time capsule machine as hard drive was crashing and replaced with new hard drive.

  • Macbook pro beeps multiple times but will not start. Unit is two years old.

    two year old MacBook Pro won't start. Beeps multiple times and black screen.

    On startup, are you hearing three beeps, then a pause, and repeating three beeps?
    If so, that indicates a problem with loose or bad RAM sticks.

  • MacBook Pro Beeps Three Times on Start-Up

    I recently got a used MacBook Pro from my uncle, so I would have a laptop for college. When I start it up (with a new Snow Leopard install disc), it beeps three times. I've looked this up to determine it's an issue with the RAM, so I bought a new 8GB stick from OWC, and installed it. It is still beeping three times on start-up.
    When I boot without the start-up disc I just get a flashing folder with a question mark in it (no OS found, that's why I need the install disc).
    It no longer has a service contract (from early 2011).
    Help on why this thing is beeping at me would be appreciated.

    What kind of RAM is in the second memory chip slot?
    Usually these are sets of two, and matching is best.
    •Maximum Memory    16 GB (Actual) 8 GB (Apple)
    •Memory Slots    2 - 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM
    Rarely would anyone install only one RAM chip, and
    when a computer such as yours can use say, 8GB a
    credible path to 8-GB would be two 4-GB/matching.
    Or if you had a good 2 or 4 GB chip, it could occupy
    the second slot for a slightly uneven workable match.
    {What were the two RAM chips removed from the MB/Pro?
    ...At this point, I'd venture to guess they probably are OK.}
    And there can be an issue even with RAM of the same
    spec numbers, some of them for a PC or iMac will not
    do well in an Apple portable, though of similar spec.
    However I get the impression there is a hardware failure
    at some other point, to include a bad hard disk drive..
    A diagnostic is recommended since most usual startup
    sequences do not work; so troubleshooting isn't possible
    in the sense that most users would be able to at home.
    Also a retail Snow Leopard 10.6 DVD should be of a
    newer version than the one your MacBook Pro shipped
    with, since the original system discs would have been
    one of two Snow Leopard versions. However being
    unable to boot from the DVD and have it run the Mac
    the issue may be a logic board failure, if not RAM.
    •Original OS    Mac OS X 10.6.6 (10J3210)
    •Later OS    Mac OS X 10.6.7 (10J4139)
    {specs from http://mactracker.ca database}
    Anyway, perhaps another volunteer contributor has
    ideas that may work, so I have to go about other
    obligations and have to go offline now.
    PS: I just noticed your other post, and Recovery
    could be helpful, but may rely on the Apple ID
    of the previous owner if an older OS X 10.7 or
    later was installed & still present in the MB/Pro.
    Usually a purchased code was involved in a
    new install of Lion, via the Mac App Store while
    MacBook, etc was running in SL OS X10.6.8...
    Good luck & happy computing!

  • My MacBook Pro beeped when I started up. Never happened before. I want to get it looked at, but I'm living in Antalya, Turkey right now. I will be in Athens, Greece until January 1st-are there any Apple stores in Athens? Please help. Thank you.

    I have a mid 2012 MacBook Pro and it started to beep for the first time when I started up today. I think it was 3 continuous beeps then a pause. It sounded like an alarm and totally freaked me out. Then I pressed the on/off button for about 5 seconds and it restarted. I was able to get online, but then I had trouble with the trackpad, which is okay now. I have AppleCare and want to take it to an Apple Store, but I'm currently residing in Antalya, Turkey. I will be in Athens, Greece until January 1st. Are there any Apple Stores in Athens, Greece that I can take it to or Antalya, Turkey???  Thank you.

  • Macbook Pro beeps on close lid -Bootcamp XP

    Recently my Macbook Pro began beeping (like a system beep) a solid tone whenever i close the lid in windows xp, running under bootcamp. I have no clue how to fix it or why its doing it. The computer is of course trying to go to sleep when the lid is closed. It only lasts a couple of seconds most of the time, but when windows takes a little while to sleep it will continue producing a tone until the computer is asleep...
    Any ideas?

    Try resetting your SMC.
