IMac Intel Start up

Turned off my new iMac for a few days. Tried to start up and get the power light, a short whirring sound, and a black screen. No blue, no chime. Tried unplugging the power cord at the machine and at the wall. Has anybody else had this problem?

Don't know what the problem was exactly, but the Apple Store in Pentagon City gave me a new computer as the fix.

  • Imac intel start up problems and fan runs constantly on high

    I got my Imac 17 Intel Duo Core on March 16th and 10 minutes after I started it the screen went black and a little light started flashing on the lower right. After holding the power button it finally turned off but would not boot up, just that black screen and blinking light. I was told by tech to unplug everything for a few minutes then put the plug in just the Imac, then hold the power button down while plugging it in. Well it started after that but the fan was on high constantly. This was remedied by unplugging everything for a few minutes and then starting back up normally. Now it runs in stealth mode being virtually silent. If your Imac intel is making noise it's not normal. Check out this site for noise problems.

    I second Dave it needs to go back to service. What I have heard happens sometime is one of the temperature sensors is either not put back on properly during reassembly or it comes of soon after. With an incorrect temperature reading that particular fan will run at full speed. You can check the fan speeds by installing iStat Pro: http://www.versiontracker.com/dyn/moreinfo/macosx/27037

  • IMac (Intel) starting up in "DOS"?

    I just got an iMac 20" (1.5gb RAM - 1gb of which is 3rd party/Kingston, 250 gb hd). When I start up or restart, the screen goes gray, then black and it goes through a boot process (white text on black) that looks something like starting up in MS-DOS. It eventually gets to the login screen and otherwise seems to work fine.
    Any suggestions/ideas would be appreciated.

    It sounds like you are starting up in verbose mode. Hold the Command-Option-P-R keys during startup and this will reset your pram and nvram. This should put your default back to full mode. Keep on holding the keys until you hear at last 3 bongs (each bong is a restart of the computer).

  • My Imac Intel 17" does a double start up sometimes

    Twice now in the two weeks I've had my Imac Intel it did a double start. I press the on button and it does the mac sound, then about 3 or 4 seconds later while the screen is still black I hear the mac sound again and it boots again. Has anyone else had this problem and is it a prelude to bad things to come??

    The first thing that your Mac does when you hit the power button is check the RAM, if the RAM appears fine it sounds the startup chime. Next it starts looking for a boot volume. It sounds like this process is being short circuited and starting over; checking the RAM, sounding the startup chime and then looking for the boot volume again.
    Perhaps you should startup from your Install DVD and use Disk Utility to repair your startup volume if perhaps something isn't kosher.
    Here is Apple's Knowledge Base info on the Intel startup sequence;

  • FCE HD won't start on my brand new iMac Intel!!!

    Hello,
    Can anyone help?
    I just bought a new iMac Intel 1,8Ghz - 17' and my FCE HD doen't want to start anymore...
    I keep receiving an error message when its starts.
    Message says something like:
    "Software or Hardware Compatibility problem.
    --> AGP graphical card"
    I downloaded the upgarde 3.0.1 form apple's website but I get a message saying that the update is not needed...
    Can anyone help, please?
    Jean-Pascal.

    Hi Jean-Pascal, read this link for a workaround but be aware that FCE may not work as fast on an Intel-Mac.
    http://discussions.apple.com/thread.jspa?threadID=385387&tstart=0
    You could try the last and simplest suggestion on this link first - namely just press "esc" when the error message appears.

  • Imac intel freezes while starting

    Hi,
    my friend's imac intel duocore freeze in the late stages of the starting process. This appeared after running latest software update package, including iphoto, ipod, itunes, quicktime, keynote ....
    Next, I started from install disc, repaired permissions, repaired disc with disc utility, which reported some errors, but told me, it was able to repair.
    Unfortunately, this did not change anything!!
    What should I do?
    - run diskwarrior (3.0.3)?
    Or will I have to install a new system?
    If yes, is there a way to keep the old data?
    The other thing I missed: when booting from cd, I expected to be able to see the harddrives data, but it was not! How can I access it.
    If nothing helps, I'll run the imac as a slave disk of my ibook to backup!!
    I'll hope there is someone to assist me a little bit!
    Thanks in advance!

    oh, I'm sorry.
    looking into one the lates threads I found a million things to check before asking questions in here - sorry!

  • Our iMac (intel) just started to hum loudly.  It is like the fan is stuck on.  Any ideas?

    Our iMac (intel) just started to hum very loudly.  It is like there is a cooling fan stuck on inside the computer.  Any ideas what this is?

    Diana,
    We don't know what machien you have or the version of OS X it is running because you haven't completed your profile. I would start though by doing a SMC reset.
    SMC RESET
    Shut down the computer.
    Unplug the computer's power cord and all peripherals.
    Press and hold the power button for 5 seconds.
    Release the power button.
    Attach the computers power cable.
    Press the power button to turn on the computer.
    PRAM RESET
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.

  • Intel imac wont start after changing permission

    intel imac wont start after i changed my hard drive permission to let me read and write, then i clicked apply to all enclosed files.i turned it off no problem. then it never started up again in os x. the grey screen with apple logo appears,then after a minute it restarts, and will keep doing that if i let it. i can start up in windows xp, but i dont know how to do anything in windows xp that will affect os x. i can use the hard drive in target mode, but i cant figure out how that can help me. i use a macbook to view target disk. ive spent hours looking through help and support. finally i do not have the os install disks. PLEASE HELP!

    My apologies for the inept instructions.
    Restart normally. Open Terminal in the Utilities folder. Paste the commands in the Terminal application to avoid typos:
    sudo su
    Press RETURN. Enter your admin password when prompted.  It will not be echoed to the screen. Press RETURN again. Now paste each of the following at the prompt and press RETURN after each.
    chown root:admin /Applications
    chmod 0775 /Applications
    chown root:admin /Library
    chmod 1775 /Library
    chown root:admin /System

  • Imac Intel will not boot up - 3 days old, light on, starts to spin...

    I got an Imac Intel 20" from my husband on mother's day and it now will not turn on!! White light comes on, sounds like it is trying to boot and then nothing... blank screen, no beeps - have unplugged and restarted, tried a million key combination from the forums and still nothing... locked up once on "Garage?" software (according to son)... worked for 2 days...
    Very dissapointed and sad... husband looking like the PC is still a better box even after breaking down and getting the Imac - can't help much because this is all new to him...
    Help!

    If you bought your imac with a credit card anywhere in your home state(or within 100 miles of your home in another state), then you can return it within 30 days if you are unsatisfied. That is federal law, and a store cannot do anything to deprive you of those rights--no matter what they say (or what they print on the receipt under your signature). My Apple store tried to tell me they only allow returns for 2 weeks. I told them the were violating federal law and they were required to issue a credit for the amount of the return, and they reluctantly complied.
    I believe credit card companies are now required to print those rules on your bill (mine does and I don't think it would do so voluntarily), so you can check the fine print on your last bill and read them.
    So, if you meet the above requirements, take your imac back . Insist on a refund. Be firm. If the retail person won't do it, tell them you want to speak to a manager. Once they credit your account, walk up to another retail person and tell them you want to buy a 20" imac.
    If the retailer won't credit your account, then call your credit card company, and tell them you tried to return a defective product within the 30 day limit that you bought in your home state, and you would like them to reverse the charges.

  • I have an iMac(Intel) Desktop computer.  I cannot print anything as it is telling me that it is "offline" How do I start it working again?  My Lexmark Printer is in working order as I have just photocopied a document successfully.

    I have an iMac (Intel) Desktop computer.   It will not send a message to my Lexmark printer because it says  "offline".   My Lexmark printer is in working order as I have just successfully photocopied a document on it. 

    That message means that the computer cannot see the printer on its network.
    Is the printer directly connected to the computer with a USB cable, or is it a network printer (either wireless, or wired to the router with an Ethernet cable)?

  • Full Firewire Port Failure (three different machines : iMac Intel, iMac G5, Black Macbook)

    I'm experiencing a failure of all FireWire ports on all of my three machines. I believe this problem began with a faulty external, FireWire powered hard drive from G-Tech. Here are all my specs, followed by a rundown of the order of events that has lead to this situation, followed by the various troubleshooting I have done.
    Equipment :
    iMac Aluminum Intel - 24" Mid 2007 - running OsX 10.5.8 - currently 1 FW400 and 1 FW800 ports disabled
    iMac G5 - 20" - running OsX 10.5.8 - currently 2 FW400 ports disabled
    MacBook - 13" black Early 2008 - running OsX 10.5.8 - currently 1 FW400 port disabled
    2 500GB G-Drives (by G-Tech) - AC powered
    1 5TB G-RAID Drive (by G-Tech) - AC powered
    1 250GB G-Drive Mini (by G-Tech) - FW powered
    Initial Setup :
    1 500GB G-Drive connected directly to iMac Intel via FW800
    1 500GB G-Drive connected to first 500GB G-Drive via FW800 (daisy chained)
    1 250GB G-Drive connected to second 500GB G-Drive via FW400 (daisy chained)
    1 5TB G-RAID connected directly to iMac Intel via FW800>400 adapter
    Sequence of Events :
    I had transferred some files to my G-Drive Mini in order to move them to my MacBook from my iMac Intel. I copied the files to the G-Drive Mini and ejected it normally and plugged it into my MacBook via FW400. The drive would not mount, and the power indication light would not go on. After experimenting with various connections and cables I was able to get the drive to power with FW400 and USB connected at the same time, but the drive would still not mount.
    I then plugged the G-Drive Mini back into the 2nd 500GB G-Drive as it was previously connected via FW400. This action caused the G-Drive to immediately reboot and eject itself from my iMac Intel.
    I then attempted to plug the G-Drive Mini into my older iMac G5 via FW400. Immediately upon plugging in, the computer shut down, and would not restart.
    At this point I kind of started to freak out. I was unaware of the extent of the damage, but was upset that the FW powered G-Drive Mini had shutdown my iMac G5. I contacted G-Tech Support and they offered to replace the drive and instructed me how to manually reset the computer's SMC by opening up the iMac and finding the Cuda switch. This worked and the computer was able to start and function again, but the FW400 port seemed to be disabled.
    I then tried to swap out configurations and drives on my iMac Intel to see if there was any cable problems, but doing so, slowly rendered all my FireWire ports useless. It's almost as if the act of plugging in the FW-powered G-Drive Mini started a kind of shortout chain reaction. I soon learned that none of my hard drives would connect to any of my three machines, with any kind of cable combination via FW400 or 800.
    I am currently able to connect my 5TB G-RAID drive to any machine via USB, as well as my G-Drive Mini. I am unable to access the other two external hard drives, as one has only FW400 and 800 ports and the other's USB connection is not functional as well on any machine.
    Troubleshooting Steps Taken :
    I have on all machines, reset the SMC in the following methods. iMac G5 - manually, by opening the case and pressing Cuda switch. iMac Intel - unplug, hold power button, restart method. MacBook - unplug, hold power button, restart method.
    I have also on all machines, reset the PRAM by the Cmnd + Opt + P + R method at startup.
    I have also unplugged all cables / removed battery, from all machines and left alone for a period of at least 12 hours, then re-plugged in each device one at a time.
    I have also restored my hibernate mode (through Terminal) on my iMac Intel to mode 3 and also turned on Virtual Memory in system preferences and set hibernatemode to mode 7, the restarted and attempted to plug in devices. The reason I even began to deal with the hibernate mode was because I had around the same time my ports began malfunctioning, installed the DeepSleep widget, which allows you to control your computer's hibernate mode. I thought that tweaking with this setting may have made my computer incapable of recognizing devices that were plugged in. I have since uninstalled the widget and experimented with different hibernatemodes to no avail.
    I also have Repaired Disk Permissions and Repaired Disk on all my machines, from within my Admin User as well as from the OsX Install Disk.
    Sometimes in my System Profiler (like right now for example on my iMac Intel) my computer is "Unable to list FireWire devices," but sometimes, no warning message comes up and it simply displays the appropriate Bus speed.
    I also conducted a system restore using a backup from my 5TB G-Raid Drive via USB, to a date before these problems started, but my ports are still not working.
    Summary :
    I am looking at a situation where all my FW ports on all my computers appear to be disabled, and possibly also on my four external hard drives, with one possible USB port malfunction on one external drive. The only root of this seems to be a malfunctioning FW-powered external hard drive.
    Is this possible? Has this happened to anyone else before? G-Tech assures me that it is impossible for my 250GB G-Drive Mini to draw enough power from a computer to permanently disable any ports, but I have tried all of the FW port problem troubleshooting steps and am at a loss.
    I do not have AppleCare and would like to avoid bringing two iMacs, a MacBook and four hard drives to the Apple store and take my chances with the geniuses.
    I would appreciate any help or advice you all have. Thanks for reading and for your support!

    Ok. So if that was too confusing, I've re-labeled this post with letters for my hard drives and some mapping of the connectivity configurations I have attempted.
