My imac G5 turns off on mi then dont want to turn back on at all but after one day turns on mormaly then turns back off again

my imac G5 turns off on mi and dont want to turn back on at all but nex day tuns on normaly then tuns back off again

It could be several possible issues.
1)  Your G5 iMac could be overheating.  Depending on which model, you might be able to open the back by yourself (not on an iSight model), and using a can of compressed air, youcould blow the dust out of it.
2)  The power supply could be going bad.
3)  The hard drive could be going bad.
There could be several others.
If you have the original, came with the iMac when purchased new Install Disks, you can try running the Apple Hardware Test to see if it can determine any hardware issues.  It can't always find the problem.
Good luck.

  • My iPhone 4 is only 14 months old over dropped very well looke after, one day the lock button stops then the volume buttons, now the headphone port does not work and the battery lasts about 4 hours after full charge I still have a year left on my contract

    My phone is 2 months out of warranty, it's never been dropped or miss used yet the past week every day something has gone wrong with it. First the lock button stopped then the side volume buttons. Then the head phone port when I putt headphones in the phone turns the volume
    Down automatically and it won't turn up until I take my headphones back out. The battery lasts 4 hours max after a full charge and today I took my phone off the docking charger and all my music has gone! The phone is breaking down more and more everyday what is going on! I know people who have had there iPhones years an non of this happen! I still have a year left on my contract too!

    Who is your carrier and what is your coverage with them? If you are with say Verizon, and have Total Equipment Coverage or Extended Coverage, they will swap it out for you under Manufacturer Warrantee.

  • How do i put info thats on a cd onto my new imac that i bought last week.  I want to buy microsoft office for it but dont know how im going to put it on the computer

    How do i put info from a cd  on my new imac that i bought last week since there is no place to put a cd?

    If you have another Mac with an optical you might be able to use remote disk. Otherwise you'll need to either purchase software that can be installed from download or purchase an external disk drive. Practally any cheap drive from places like OWC, Amazon or NewEgg will work.

  • Losing iCloud emails - when I receive emails into my iCloud accounts they disappear very quickly, either after one day or once I've opened one of them on either my iMac, laptop, iPhone or iPad.  I've checked all my account settings and they seem fine

    I have 5 email accounts, 2 iCloud based and 3 using another provider.  When the iCloud mail arrives on any device and either it's opened or a day passes, they disappear...sometimes into Trash and sometimes who knows where.  I've checked the settings on every device and they seem correct, and identical to my non-iCloud accounts.  I had this problem once before and frankly don't recall how it was resolved, which obviously wasn't successful.
    Any ideas?
    Thanks,
    Al

    Yes, post your settings here, if you really have verified the settings and they are correct there is nothng else to offer, so post them here and let others advise as to their 'correctness'

    Try:
    - iOS: Not responding or does not turn on
    - Also try DFU mode after try recovery mode
    How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
    - 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.

  • Frustratingly, since I upgraded to Yosemite 10.10, I too am having the worst problems with WiFi dropping out. I've never had this problem before on my iMac 27-inch mid 2011 model. Turning WiFi off and then back on again sometimes works. Help please.

    Frustratingly, since I upgraded to Yosemite 10.10, I too am having the worst problems with WiFi dropping out. I've never had this problem before on my iMac 27-inch mid 2011 model. Turning WiFi off and then back on again sometimes works. Help please. I've already tried a lot of your suggested fixes, but without success. Why hasn't Apple Fixed this?

    Please test after taking each of the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes.
    Step 1
    Take the applicable steps in this support article. The Wireless Diagnostics program generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
    Step 2
    Disconnect all USB 3 devices. If you don't know which are USB 3, disconnect all USB devices except keyboard and mouse.
    Step 3
    If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. If you find that Wi-Fi works better with Bluetooth disabled, you should use the 5 GHz Wi-Fi band. Your router may not support it; in that case, you need a new router.
    Step 4
    Open the Energy Saver pane in System Preferences and unlock the settings, if necessary. Select the Power Adapter  tab, if there is one. Uncheck the box marked
              Wake for Wi-Fi network access
    if it's checked.
    Step 5
    Open the Network pane in System Preferences and make a note of your settings in the Wi-Fi service. It may be helpful to take screenshots of the various tabs in the preference pane. If the preference pane is locked, unlock it by clicking the padlock icon and entering your administrator password. Delete Wi-Fi from the service list on the left by selecting it and clicking the minus-sign button at the bottom. Then recreate the service by clicking the plus-sign button and following the prompts.
    Step 6
    In the Wi-Fi settings, select
              Advanced... ▹ TCP/IP ▹ Configure IPv6: Link-local
    Click OK and then Apply.
    Step 7
    Reset the System Management Controller.
    Step 8
    Reset the PRAM.
    Step 9
    Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
    Step 10
    Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

  • My Imac will suddenly turn off without warning and then take several hours before it will switch back on again

    My Imac will suddenly turn off without warning and then take several hours before it will switch back on again. Can anyone advise?

    I like that third tag...
    There's really no telling what the problem might be - you may want to try running the Apple Hardware Test (if you can) to see if you've a hardware issue. If you can't even get to the AHT, you've no option but to take the machine into your local Apple Store or an AASP and have them run diagnostics on the machine.
    Sorry,

  • IMac shut down unexpectedly. I tried to restart and it did for a bit, then immediately shut down again.  I've had it for 3 years and this is the first problem. I can't turn it on to give specs.  Any suggestions?

    I purchased an iMac approx 3 years ago.  We keep it on almost all the time, however the other night we noticed it was off.  We did not shut it off as we were downstairs watching a movie.  I unplugged the cord, waited 10 to 15 seconds, plugged it back in, wait for a few more seconds and turned it on.  It started up and was almost done booting.  Then it shut down again and I have only gotten it to attempt to turn on.  (the fan kicks in for about 2 seconds and then nothing) Any suggestions?

    Try that process of resetting the SMC two or three more times, sometimes it takes more than once. if that doesnt work I could only suggest making an appointment and hauling it in for service.

  • My iphone wont open, i even recovered it but to no avail, all it does is go to the white screen with the apple logo then turn off again

    Hey everyone,
    This morning i took my phone out of the charger and everything was normal however, once i got in the car i looked at my phone and realized it was turned off. I tried turning it on again as well but all it does is going to the start up screen (The white screen with the apple logo) and then it turns off again as well. I also put it on the charger but it does the same thing but repeatedly. So it just goes to the white screen and off again. At last i resorted to recovering my phone even if it meant losing all my data. Slow internet connection meant it took all night but in the morning i recovered and everything and got to the last step ( It told me its finished but i should leave my phone connected to itunes and it will pop up there) but all that popped up was an error screen. It still broken but now sometimes when i try to turn it on the same white screen with the logo comes on with a bar under it. this bar fills up a little then the screen goes black again. Is there any other way i can try to fix this?
    P.S. There are no apple stores in my area so i took it to one of the phone stores here and even they said they couldnt do anything about it

    Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Power off and then back on your router
    - Reset network settings: Settings>General>Reset>Reset Network Settings
    - Reset all settings
    Go to Settings > General > Reset and tap Reset All Settings.
    All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
    - Restore from backup
    - Restore to factory settings/new iPod.

  • I was downloading the update on my iphone4 and then it turned off and told me to connect to itunes and now it wants me to recover it but i dont want to lose my stuff

    I was in school earlier today and noticed that my iphone 4 needed an update, so  started the update then after like 2 mintues my phone turns off and when i tried to turn it back on it told me to connect to itunes. Now im connected and it tells me i must restore my phone...And i really dont want to lose my pictures and stuff like that so someone please tell me what i can do...

    Sorry, you have no choice but to restore your phone now. If your data was not backed up before you attempted to update, it is gone.
    Next time, backup before you attempt to update.

  • I have a Seagate Freeagent 1TB external drive that ejects it's self in the middle of the time machine backup, then disappears and can't be found unless I turn it off and back on again

    I have a Seagate Freeagent 1TB external drive that ejects it's self in the middle of the time machine backup, then disappears and can't be found unless I turn it off and back on again. Any ideas?

    Hmmm.. sorry to jump in but...
    I Wish I had seen this before I got mine.
    Mine has been doing this auto eject stuff too.
    I think I just plugged it in and TM let me select it but is it possible
    I should have reformatted it with DU first, like with all the WD drive problems ?
    Is it too late for that ?
    Or just try to return it or get rid of it ?
    TIA
