HT202731 my imac goes to homescreen but no icon or start menu

my iMac boots to blank homescreen.could someone please help..running osx10.6 8

Hello,
At this point I think your best bet is to take it in for servicing at the local service center.
As for your data, I think odds are that it is still in-tact. The type of failure you describe sounds more like a failed logic-board or possibly the power supply (improper voltage / low-voltage).
Most likely it's a failed logic-board. But, the power supply can cause these symptoms as well.
Neither would mean that your hard drive is bad. It's possible that it is, but it's not an automatic definite.
If it were only the hard drive that failed, then you'd get the grey Apple screen with a flashing question-mark.
So, what I would do, is request them to fix the computer. But, I would put a stipulation on it that requires them to call you if they are going to re-format or replace the hard drive.
This way you'll know in advance if they are going to erase your data. You could then decide whether to pay them to archive it onto another media or back it up for you, or just let it go.
Explain to them that you have information you are concerned about saving. And, request them to at least let you know if their repair process is going to require them to do anything that might erase the hard drive.
I think that's about the best you can do at this point.
I hope this helps.

    I hold my finger over the app I want to delete, but the icons never start to wiggle. What do I need to do?

    You are pressing on the app, right? Are others jiggling? There are some system apps that cannot be deleted, such as phone, calendar, ipod, etc.

  • IMac sees the iPod but iPod does not start up. It had coffee spilled on it

    My iPod had coffee spilled on it and it was not discovered for a bit. I dried it in rice and now the iMac sees it but it will not turn on. I did try to turn it on when I found it and I know now that I should not have. What parts may be bad in it now? should I try replacing anything in it or what? any advice is appreceated

    Hey mjrussell,
    When liquid comes to liquid being spilled on a iPod, you never know how bad it will be. Your best bet if you want to get it fixed is to set it for serviced through Apple. Take a look at the articles below for more information. The second article will also have pricing for your iPod nano.

  • When downloading an app, it goes to 'Open' but no icon appears on home screen. In storage it's name is showing "null". I have lots of memory available.

    Any ideas on what the problem is and how can I fix?

    Which app icon is missing?
    Are you sure it wasn't moved?
    Have you checked on another page or in folders?
    Does it show in spotlight search? (Swipe down from the center if the screen)
    Check your restrictions:
    Settings > General > Restrictions
    You can also try resetting your Home Screen Layout:
    Settings > General > Reset > Reset Home Screen Layout
    Delete it:
    Settings > General > Usage > select the app > Delete
    and redownload:
    Open the App Store > Updates > Purchased

  • HT1776 Hi, my iMac screen goes to sleep but the fan stays on 24hrs and never stops?

    Hi, my iMac screen goes to sleep but the fan stays on 24hrs and never stops? You can hear it running all night.
    Appreciate any advice.I'm using Lion. Many problems started since using Lion!

    The temps are a bit higher than I'd expect under normal circumstances, and too high while playing games, but what is the room temp where it is?
    I def. think its a temp thing now. but why does it only raise when im playing games or watching videos online?
    Games tipically press the CPU, Video Card, RAM, and everything else much harder than most apps.
    It may be a Fan not working properly, or just dust buildup.
    Boot off your Install Disk while holding down the *d key*, (not c key), then run the extended Apple Hardware Test. Some disks require you to use the Option key at bootup to select AHT. Some models have a separate AHT CD.
    Report any errors it finds.

  • My iMac goes to disc utilities on startup, repair disk doesn't cure it and I can't reinstall Mountain Lion because I don't remember my I'd and password at the time I bought the software. Currently working abroad and at a loss can anyone help please?

    My iMac goes to disc utilities on startup, repair disk doesn't cure it and I can't reinstall Mountain Lion because I don't remember my ID and password at the time I bought the software the system isn't accepting my current details and Apple isn't recognising the answers to my security questions.  They don't even seem to have my correc date of birth so I can't progress the reinstallation.  I'm currently abroad and have my iMac with me but with no way of contacting Apple that I can find, I'm at a loss and very reluctant to pay £35 to try and get my ID and pasword sorted out given that their system recognises my current details.  can anyone help please?

    when they gifted me the mountain Lion software several years ago.
    Mountain Lion was introduced in July 2012. Did the people who gifted you possibly use their Apple ID for the purchase of your OS? If you used your own Apple ID, you should have simply used the one you use for all things app store. The problem with any purchase at the app store is: whatever Apple ID was used to purchase, it willl stay tied to that Apple ID forever. And, purchases from the app store are not transferable.
    So, you can check with the person(s) who gifted you or spend $20 to buy it - or, if your hardware is compatible with the new OS Mavericks, you could download it and associate it with your Apple ID.
    FWIW, according to the licensing agreement, the OS remains the property of Apple and you are only granted a license to run it.

  • IMac goes to sleep unexpectedly, Finder issues with flash drives - related?

    My iMac falls asleep for no known reason, often in the middle of active use. (Similar problem recently described in thread with messageID=11829917.)
    Sleep onset is frequent but seems to vary based on both currently-running software and attached devices (particularly USB flash drives). It will almost always wake up when I hit the space bar afterward, but might sleep again within a minute or two, then not for an hour or more. The sleep occurs with little notice (brief stall of display, sometimes enough time to click on another app window and bring that forward before the screen goes dark), and 95% of the time the computer wakes up after hitting the spacebar. The other 5 % of the time the display reappears but the entire OS is frozen and usually requires unplugging the power cable. There are other symptoms in the Finder - more below. Once in a while the fan revs up like a WWII fighter plane taking off from a carrier, but this is unusual and all the really irritating stuff also happens without this symptom, which usually stops on its own. Immediately after reawakening error messages are displayed to report that flash drives were improperly disconnected (Tell me about it! This has been the case for several months whether the computer goes to sleep by itself or if I put it there manually.)
    The computer seems to go into sleep mode most frequently when not-particularly-demanding graphics (Photoshop Elements and Adobe Reader) and video (QuickTime Pro 7.6.4) apps are running. Turning these off makes nod-offs less frequent but doesn't stop it entirely. When video thumbnails are displayed in Finder windows a lot of time may be required to load the data and this often paralyzes everything else AND this also seems to be a trigger for a nod-off (i.e. QuickTime not necessary to make the computer choke). This is highly variable and some video clips load quickly (< 20 sec), while others take several minutes, and this doesn't necessarily correlate with file size.
    Another factor is whether flash drives are connected - these seem to make the nod-offs more frequent AND Finder regularly loses communication to these both while just sitting there and also in the middle of file transfers. A very early 250 MB drive (Lexar - vintage 2004) will always communicate, but different USB2-capable drives all are either unreliable (Lexar 8 GB and KData 4 GB both < 1 yr old) or apparently dead (Lexar 2 GB ~ 2 yr old). The failures may be damaging the drives - they are inconsistent-to-bad at communicating with my MacBook Pro. I know this sounds like the drives are at fault, but there are things which make me suspect the OS (both computers use the same version): 1) different flash drives display the same on-again-off-again behavior AND the 2) the 2 GB drive that hasn't communicated with my Macs in over a month has no trouble talking with my wife's WinXP computer. When communication isn't working with these drives, they do not show up in either Finder or Disk Utility. When the Mac-dead 2 GB Lexar is plugged into either computer and I launch Disk Utility, the initial scan for drives never finishes so I have to force quit. (When they are working, on the iMac the large drives only appear in Finder if I go to User and press Command-uparrow (to go up a directory layer) - in columns display mode nothing appears in the left-hand column.
    (The following describes a set of problems I've had a little longer and which may or may not be related):
    At times the Finder loses some but not all functions:
    1) Sometimes files in the Trash can't be ejected* even when all apps are turned off
    2) usually when problem 1) is observed, no keyboard commands work: nothing happens when pressing Command-W, Command-uparrow or Command-N to open a new window. Text typed will not be entered to change filenames (but this can still be done by typing the desired text in TextEdit, copying there and selecting and pasting with mouse commands.)
    <* I have downloaded an app for forcing file deletion, but haven't really needed it - the delete option and keyboard commands all return after shutdown and reboot, and there's usually enough annoying stuff going on by this time that that seems the best thing to do.>
    Things which I've tried to fix it with so far (not in this order):
    - blowing dust out of the back with canned air
    - checking temperatures - CPU/GPU showing 72/73, HD bay 51, etc.
    - fixing permissions from normal boot
    - boot from install disk and running extended hardware test (no problems found during scans repeated several times during the past month)
    - fixing permissions and running Disk First Aid from install disk boot
    - getting files off the hard drive (was as low as 3 GB free space, currently ~ 35 GB and climbing)
    - clearing PRAM
    - resetting system manager (name? - hold down power button when reconnecting power cable, etc.)
    - Power Saver display and computer auto sleep are shut off (both on "never" - I regularly put it to sleep manually)
    - virus scans (Clam XAV)
    I realize that this is a kitchen sink collection of symptoms, but these things may be related and if so, OS developers may want to be sure these problems are avoided in current versions. (Yes I will upgrade my OS soon...)

    Thanks for checking in, Miriam - sorry to get testy about it.
    The iMac's RAM is maxed out (2.5 GB)
    Yes, the system log does report overtemp message to Power management prior to shutdown (today's log at end of post)
    Where do I find normal temperatures for the system? What are the important parameters to watch and what sort of fixes are possible?
    iStat currently shows:
    HD 54° CPU 67° GPU 72° Incoming air 38° (???)
    HD bay 54° GPU ambient 71° opt drive 49°
    ==========================================
    Console.log was largely full of stuff about a bad flash drive I stuck in as a Hail Mary and failure of communication with a scanner (old HP, driver package installs a program which starts at launch which doesn't show up under Startup Items. Apparently the permission got mislaid, so I fixed permissions and this seems OK now. (Only included that because some of it shows up in System.log and it's not worth focusing on.)
    [That all said, there is a software/OS component to the problem and it is graphics-related. The other night I was looking at some flash videos in a series and one in particular repeatedly caused shutdown, while others played normally: domain = jebhost.com /youtube/list.php?q=Henry+8.o&Submit=GO "The Tricycle Thief" only played through once out of about six tries.]

  • My Imac 27' screen is shutting off for no reason. The Imac is still running but the screen is black and stay like that. Is there anyone else with the same problem, and does somebody know what is this?

    I had my Imac27' for about 1 year (I bought it january 2011) , and it worked fine. But two days ago a problem started. The screen is turning black suddently, and it stay like that until I reboot it. It's not cool. The first time it happen it was hafter a very long days of video editing, I tought it was to hot. But now I just started up the Imac and 10 minutes later it happen. And now  I transfer my desktop on my second screen, because the one of my Imac is constantly shutting of. What is this? Can I do something about that?

    I´ve came across with the same problem and when I look out for solutions I found out that basically I had Three options
    1.- Dim the brightness to the first 2 dots (that is the limit for me, anything above that shuts down again my screen)
    2.- Replace an expensive part of the screen (about $900)
    3.- Try with an external monitor to see if the problem was the screen or something else
    What I did was to plug my flat screen to my mac with a Mini Display Port to VGA Adapter
    http://store.apple.com/us/product/MB572Z/B/mini-displayport-to-vga-adapter?fnode =51
    And… Problem Solved! now Im going to buy a Monitor that gonna cost me less than half of the replacement parts, my main monitor will keep siting down if i dim it above the 2 dots but at least I will have the other to work properly
    So that´s that, I hope someone finds this helpful
    P.S. Sorry if my english it´s not that good

  • IMac goes into sleep, can't turn back on...

    A new problem has risen...iMac will randomly go into an unwakeable display sleep and the only way to turn it back on is by pressing the power button and either shutting it down or putting the computer (not the display) into sleep. A non-threatening problem, but it proves itself to be quite annoying.
    I have looked in System Preferences and made sure to check that the computer will 'never' go to sleep, both the display and computer sleep, and that bluetooth devices will wake the computer (just in case it goes into sleep), but it still continues to carry on it's uncalled sleeping. Any suggestions? All comments are welcome, and many thanks.

    HI,
    Install the 10.5.8 combo update available here.
    http://support.apple.com/downloads/MacOS_X_10_5_8_ComboUpdate
    It's ok to do that even if you are already running 10.5.8. If that doesn't help ...
    Try resetting the SMC.

  • I have a year old iMac and Macbook, both on 10.7.3.  Every time the iMac goes to sleep I lose wi-fi.  No problem with the Macbook and iPad.  A lot of people seem to have the same problem.  What's the solution?

    I have a year-old iMac and Macbook, both on 10.7.3.  Every time the iMac goes to sleep I lose wi-fi from  Airport Express.  No problem with the Macbook or my iPad.  It seems a lot Mac users are having the same problem.  Is there a solution?  Does Apple have a solution?

    Sometimes there are problems.
    Somethings to try but probably won't help....
    1. Repair Disk Permissions
    2. Startup in Safe mode by holding down the "Shift" key....
    3. Reset the P Ram by holding down the "Command/Option/P/R" keys at the same time...
    The above are standard items to do on any Mac from time to time.
    I repair permissions at least once a month....
    The other 2 periodically as they do straighten things out when they get out of whack....
    Thanks for the feedback.

  • Imac goes to sleep when downloading and errors occur

    I have a Imac and whenever i download largish programs from  the appstore which take a little while to download, the Imac goes into sleep mode and when i restart the imac, the download has stopped and says an error has occurred. I then have to restart it and resign in with my apple id and it start again.
    This isn't a massive issue on programmes which take up to 30  inutes but larger programs which take a few hours to download (I am in a area with relatively low broadband speed) I cant leave it to download and go and do somehting else or leave it over night.
    Does anyone know how to turn off the auto-sleep mode and leave it on conctantly until turned off ?
    Thanks

    Applications > System Preferences > Energy Saver
    set computer sleep to never
    set display sleep to never
    uncheck put hard disks to sleep when possible.

  • ATV looses connection because iMac goes to sleep.

    Everything connects fine and I can stream a movie or music for about 30-40 minutes then it all stops when the iMac goes to sleep. The Mac energy save options have the 'wake for network access' box checked, but it still goes to sleep. What am i doing wrong?
    Setup: iMac-Airport Extreme - ATV3

    You've reset the SMC, how about the PRAM?

  • Imac going crazy

    Help. My Imac (Intel) running OSX 10.6.7 has started going crazy - writing new file names, sending messages on MS messenger etc. Can anyone help? I tried rebooting after resetting the PRAM but with no luck. Is there anyway to set a safe mode? switch off automatically loaded programmes such as messenger? Has anyone else seen this problem? The machine is switched off pending help - I am writing this from another machine. Thanks
