Boot from the original Install disc that came with the computer and then format the drive Mac OS Extended (Journaled) using the GUID partition. Then  you can re-install OS X. If you no longer have the original media call AppleCare with the serial number of the machine (look on the bottom of the stand) and for a nominal fee they will ship you replacement media.
The chances are very good you will have fan problems if you used an off-the-shelf HD, beginning in 2009 Apple began using HD's from vendors that incorporated heat sensors into the HD. If you did not buy the same type of HD your computer will think the HD is overheating causing the fans to run at full speed.

    Try:
    - iOS: Not responding or does not turn on
    - Also try DFU mode after try recovery mode

    - If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • Have an iPod touch 4th gen.  It is completely charged, but once I disconnect from a power source it shuts down and then the apple logo just keeps reappearing.  I have restored via iTunes and reset all the settings.  Any suggestions?

    If you restored to factory settings/new iPod via iTunes (Not via Settings>General>Reset>Erase all Content and Setting) and still have the problem that indicates a hardware problem.

  • My iPhone 4 is stuck on the apple logo screen, help!

    I tryed deleting some of my most used apps, and as I was re-installing one it was taking forever so i decided to reset it by holding down the lock and home button at the same time. It's been sitting on the apple logo screen for almost an hour now and plugging it into itunes or plugging it into the charger hasn't done anything for me. I've also tryed restarting it again but it still hasn't helped. Any suggestions?

    Try restoring. I'm guessing you may have trouble doing this, so see http://support.apple.com/kb/HT1808

  • I turned my iphone 3gs off and when i went to turn it back on it just stays on the apple logo and has been like that for quite some times

    Hello, my phone was being slow so i turned it off. when i went to turn it back on it did the usually white apple logo but it has been on that logo for 15 or more minutes now what do i do?

    First thing to try is to reset your device. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider should one appear until the Apple logo appears. Let go of the buttons and let the device restart. See if that fixes your problem.

  • My iphone 3g stays on the apple logo for about 4 minutes then flashes white and goes back to the apple screen, it repeats untill battery is flat,  every now and then im lucky enough to get it to turn on but not very often and then it freezes and repeats??

    hello my name is kirstie, i updated to firmware 4.2.1 .....my iphone 3g stays on the apple logo for about 4 minutes then flashes white and goes back to the apple screen, it repeats untill battery is flat,  every now and then im lucky enough to get it to turn on but not very often and then it freezes and repeats the same problem?? (if i turn the phone off my pressing the two buttons it wont keep rebooting, its only when i leave it after turning it on)
    I have reset the phone, full firmware restore, even downgraded back from firmware 4.2.1 to .3.1.3 official by using dfu mode and still doesnt fix.
    (i correctly got out of dfu mode after the downgrade)
    i can enter dfu mode and recovery, and update through itunes with no problem, but it doesnt fix the problem,
    i have searched and found no answer to this problem, every option availible to try that i know of i have tried and failed. i dont care about preserving my content i just want a fix. i have a good understanding how to operate software on a computer and shouldnt be too confused by any advice given, so plz even if the answer is very complex i wish to try anything, please help me to get my iphone working.

    Anyone have any suggestions? or is everyone else just as clueless as me !

  • PLEASE HELP 2/24/13 Brand new iPod Touch 5th Gen froze on set up and I tried to shut it down and it was on the apple logo screen for a long time and it shut down but now it won't turn on! PLEASE HELPPPPPP

    DESPERATE PLEASE HELP So my mother got herself an iPod touch 5g for Christmas and barely asked me to set it up last night, (BRAND NEW NOT OPENED YET).. I set it up not plugged into iTunes (directly on iPod). I was setting up a new iTunes account for her (got passed Wi-fi set up and location services) and as I was doing that, it mysteriously froze somehow. So I held the home button and power button down simultaneously, which I thought would restart the iPod/shut it down.. so it did, and it was on the apple logo screen for a LONG TIME.. and when I checked after a long time, it was black. I tried to turn it on, charge, and plug it into itunes (iMac computer) and it won't turn on!!!!! PLEASE HELP

  • Pinterest was taking up 13 GB on my phone. I deleted it, it ran out of battery and when i plugged it back in- i cant get it to start off of the apple logo screen. Help!!

    My phone had been telling me i did not have enough storage- and i finally found out that pintrest was taking up 13 GB! When i found out, i deleted it. Soon my phone ran out of battery, and it was a while before i could plug it back in. Once i could plug it in it stayed on the Apple logo- and will not start. I can hold the power and start button and it will go black, but thats it. I have plugged it in but itunes wants me to restore it- we just got back from vacation and all our photos are on my phone!! I dont want to lose them!! GRRR PLEASE HELP!!!

    Here's how to perform the restore:
    HT1414
    If you can actually get to restore, maybe (I estimate a 0.01% chance) you'll be able to do a backup before the restore.  Actually, from the symptoms you describe, I suspect a restore won't work either and you'll need to do a recovery.
    Just in case, if you need to recover (restore fails), here's how.  Note you may have to try to get into recovery mode more than once.

  • IPod nano will not connect and the Apple logo screen stays up

    Hello,
    Earlier today I shut my iPod nano off normally (by holding the pause/play button). Later, when I went to listen to it again, I found it wouldn't turn on. I tried resetting it, and I got the low-battery signal, so I plugged it in. The thing is, the Apple logo screen is illuminated and I cannot get it off that screen, and normally when I plug my iPod in, iTunes comes up. iTunes didn't come up and it says there is nothing plugged in. What should I do?
      Windows XP  

    Okay.
    If the Apple logo is not going away and the iPod won't get to the main menu (when not connected to the computer), try what those links suggest.
    If your iPod does not get to the main menu or say Do Not Disconnect, it will not be recognized by the computer. You have to get the iPod to say Do Not Disconnect, show the main menu, or just get past the Apple logo before it will be recognized. The above links will help you get the iPod get past the Apple logo.
    The iPod cannot be recognized by iTunes or the computer if it is stuck at the Apple logo.
    Finally, don't connect the iPod while the iPod preferences in iTunes are open.
