Imac g5 freeses very often for no particular reason

Hi, guys, I am just frastrated!
My imac g5 freeses very often for no particular reason and it takes ages for it to load when i restart it.
does anybody know what may cause it and what i should do to solve the problem?

I first suggest that you test using the Apple Hardware disc
that came with your iMac to see if it's hardware related.
If it is hardware related,
contact Apple
Like the first replier, you might need to repair permissions,
you could use the application Disk Utility to repair it while your
system is running.
OR you could start up using the system installer disc which
also has disc utility to repair permissions and repair disc.
repairing is fast and easy
I suggest doing this once a week or two to maintain permissions.
Another possibility is that your iMac could be under the Apple Repair Extension Program since you implied that your iMac is a G5.
If you suspect that you might be under the extension program, contact Apple.
Hope this helps...

    - Apps are locked to the account that purchased them.
    - To update apps you have to sign into the account that purchased the apps. If you have apps that need updating purchased from more than one account you have to update them one at a time until the remaining apps were purchased from one account.
    You need to reactivate your first account.
    Why do I see the message "This Apple ID has been disabled for security reasons” when I enter my password?
    This message means that someone was unable to sign in to this account multiple times. The Apple ID system will disable the account to prevent unauthorized people from gaining access to your information. You'll need to follow the instructions on My Apple ID to reset your password.

  • T40 shuts down for no particular reason

    Within the past two weeks, my T40 has taken to shutting down somewhat arbitrarily. The fan seems to be working fine and it doesn't appear to be overheating. Often something like running a YouTube video is enough to shut it down.  The only thing that I have upgraded or changed besides the standard monthly Windows upgrades is the Think Vantage Toolbox.  I can't see where that would be a factor.  Battery and power supply check out O.K.
    Perhaps it is just showing it's age.  Any idea what would be causing this?
    Oh yes,  one other item, when it shuts off, I have to re-sign into my Yahoo homepage, otherwise I just get the generic Yahoo page.

    Solved!
    Go to Solution.

    Power Management was indeed the answer. Thank you for the suggestion. I didn't spot the change at first, but once I did, it worked.
    For some unknown reason, when installing the Lenovo Toolbox, the Power Manager reset the Performance setting from "Adaptive" to "Highest."  I have now created a new power scheme with everything the same except for an "Adaptive" level for the CPU speed. The CPU temmperature is back to running  a more reasonable 44C to 70C and it doesn't shut itself down like before.  Big difference.  
    My T40 is back to whatever normal is for this seven-year old modified laptop, You have no idea what a relief that is.  I was already shopping new laptops. Now, I'm thinking that this laptop can become my road warrior, and I will look for a Desktop PC with a bigger screen, instead.  That's what I had secretly wanted to do all along.
    This forum is outstanding.  It has saved me on more than one occasion.  Thank you so much.

  • My iMac 27" freezes very often...

    Hello,
    I don't know why but my iMac stops working all ~5 Minutes, even if I only have about 5 Applications open like Safari, Mail, Transmission, Adium and iTunes. I was looking for the reason by myself, for example I ran the Apple Hardware Test and I deinstalled some things I recently added. I started Activity Monitor and looked up if my RAM (4GB) is full, but I still had about 2 GB free. I don't know what to do, please help me! I want a working iMac!

    Hello,
    I don't know if our problems are linked in any way, you can see my spec at bottom, yet I think we should keep an eye on what each other are posting for a while.
    I'll subscribe to this thread.
    I will be posting my own new thread very soon and when I do I'll let you know.
    Once I get my thread up and running I recommend that you subscribe, at least until you have determined whether our issues are linked or not.
    In a nutshell:
    My iMac started showing minor graphical errors.
    Then graphical errors that caused major concern.
    Then my system suffered 'Kernel Panics', random reboots, system freezes and now will not power up.
    I have witnessed enough info on various forums, including this one, to indicate that my problem may be linked with the year of manufacture, certain hardware components and, the one that most intrigues me, the factory it was produced in.
    Our Issues may not be closely linked, apart from both having iMac's that have frozen...
    I'm starting with my eyes open to all similar problems and wont flood peoples threads with my issues, yet I will invite all to look at and join my thread if they feel it is relevant to them.
    In my thread I will be looking into the serial to begin with, which tells where and when manufactured.
    If you look at my Profile Biography, it has a breakdown of what the various parts of the serial represent. (This will be written in a clear fashion when I get my thread underway)

  • IMac screen keeps waking up for no apparent reason

    Here's a fun one. So we all know you can put your Mac screen to sleep by pressing controlshifteject on a Mac keyboard. This is what I usually do with my iMac as I tend to have it doing something at night (be it downloading, processing large files, ect.) but lately the screen only seems to want to sleep for about 10 minutes or so before it will turn right back on.
    My old MacBook Pro used to do this but you could actually dim the screen right down to zero anyway so it wasn't that big of an issue. You can't do that with an iMac.
    I've heard mention that it might be bluetooth related and I am using an Apple bluetooth keyboard and Magic Mouse but it seems to be doing it much more often of late. I thought it might be a battery issue but even with fresh batteries the issue continues.
    Anyone know what's going on?

    Next time you want to put your iMac screen to sleep, try switching off the Magic Mouse, wait for the notification to come up on the screen telling you the Magic Mouse has been disconnected, wait for it to disappear then press the keyboard shortcut to put the screen to sleep. See if that helps and we'll go from there. If that doesn't help, can you just say wether the screen always turns back on the same time every time?
    Hope that helps

  • Satellite L300D-119 suddenly shuts off for no particular reason

    Hi,
    just while I'm doing random stuff on my laptop, it just turns off. And it's not like when i press "Shut Off" from the start menu, it just completely shuts down, and the screen turns black.
    The PC itself isn't overheated or anything when this occurs.
    I'm very worried, does someone know what to do? In that case, thanks very much.

    Hello
    You must understand that nobody here can say for sure why this happen and if this happen continuously you should contact nearest service provider and ask for help.
    Let them check your notebook. The warranty is valid and if something must be done it will be done for free.

  • IPhone 4 GOES DARK RANDOMLY FOR NO PARTICULAR REASON PLEASE HELP

    I'm gonna try this. Because I'm super frustrated. Something scary is happening to my device, I got an unlocked iPhone 4 from the Beverly Center in Los Angeles 3 weeks ago. I'm now on a long business trip in Moscow Russia and all of a sudden my screen statics, a sound of plug being pulled resonates from my iPhone there is some colored lines that slowly engulf the screen and then it goes dim, dark background on the screen but there is a slight light making it all look like the phone didn't shut off, it just bugged out and is now (I guess) just dark. This all happens in a matter of a second.
    Then I hold the master restart and get it back working, sometimes after a few tries, because sometimes five master resets still don't bring it back to life, the white Apple over the dark background appears but then the phone is off again without ever coming back on.
    Sometimes it happens when I browse FB or I'm on Linkedin, but first it started happening after taking a picture with the Camera (After like using the Camera for almost 3 weeks prior). Every time I took a picture this happened. Then it moved to other programs, like I would turn on the music and same thing would happen, just goes dark-dim. Now its mainly happening while using applications, mainly FB, the ABBYY Card Reader (Camera) and even Virtuoso Piano. Also sometimes when I charge the phone through a plug it always does that the second I plug the cable into the phone. Same thing if I use the USB and connect it to my MacBook Pro (2008) it gives me a box saying "Couldnt connect to the IPhone 4. An involid response was recieved from the device" or something like that. After 5-10 tries it plug in and the iTunes syncs it and it works fine. I mean *** is going on, I couldnt buy and factory unlocked iPhone from the US for 6 months, and when I finally was back in the US and had the chance to do it, this CRAP happens I FEEL FRUSTRATED AND DEPRESSED ISNT THE IPHONE 4 SUPPOSE TO BE the toughest and most reliable phone ever to hit the planet? Why is this crap happening to me while I'm away?
    PLUS THEIR SALES REP AT BEVERLY CENTER SHAWN MCDANIEL LIED TO ME by TELLING ME THAT THE APPLECARE+ (Which I purchased for an extra 100) will take care of even 2 trade in if (PRECICELY CRAP LIKE THIS) something happens to it. THATS PRETTY MUCH WHAT HE SAID, and then when I told him that I'll be in Moscow, OH SURE THEY HAVE A REPRESENTATIVE AND APPLECARE+ IS WORLDWIDE.
    So then I call Apple Care, both the specialist and the supervisor sound like kids who were given a superjob. They don't sound like intelligent techy people and soon I understand why. Long story short, I got no clarify wether there is an official Russian Apple representative or not, I wasn't offered mail-in repair, I was only told that looks like the nearest Apple store to me is in Poland or London so I should have someone fly there (that means I won't be with my contact book for at least a week or two) or go there myself (thx I just got an $800 phone and I should get another 300-500 EURO ticket to London just to make the iPhone purchase complete) ***.
    (For those who enjoyed reading so far read below, if this information is enough for you to help clue me in I'd appreciate it, if you want to read more interesting stuff read below).
    Wait I can't make the story short I have to tell you - so the first lady sounds like a 16 year blond from the heart of Hollywood, and she tells me to do a backup, doesnt tell me how I should transfer my contacts that I had transferred into my phone from my old Samsung galaxy, xfer them into my MacBook at which they've never been. We did a full restore after saving a backup (hoping that my contacts would stay in tact) , then we found out the restore didnt fix it, as I went and took a picture this thing happened. Then I said the heck with it I need my old backup with the apps and my contacts, so I initiated that backup and then the contacts didnt xfer in, and I was shocked, literally, 1500+ contacts destroyed by Apple. So then she passed me on to her supervisor who was the one who didnt tell me anything substantial except simple troubleshooting procedures. He told me to go into a Russian iPhone Reseller and it will be at their full discretion wether they would exchange my phone for a new one or not comply to AppleCare since apperantly it doesnt work with them and nearest apple stores are in London or Poland. So whatever, I then afrer finishing my exactly (Skype call)
    11/5/11 4:52 AM Call Ended 3 hours 12 minutes 39 seconds, I, saddened, saw that in my iTunes backups I have two more backs from an earlier time, so I backed up to one of those and it xfer everything the contacts and apps! It was just enough time for me to download ExcelContact and e-mail my contacts to my gmail before this thing started happening again. My phone works now, but this thing happens now every few hours randomly and I'm outraged.
    Please if anyone experienced such a problem and could help me fix this, please help me.
    Thx
    P.S. I used the phone fine with ATT for a week in US when I bought it, then I used it fine for 2 more weeks here in Moscow with MTS GSM. I dunno wether my phone is CDMA or GSM? =.="

    Thanks for the the information Tyler. I'm still in awe, I heard that if an LCD is over heating or the phone is over heating, there would be a warning message telling me that the device is over heating, not sure how true is this?
    Nah I never dropped it yet, its too fresh and precious to me but the funny thing is no matter what care I took since the three weeks that I've had it, it still developed this problem.

  • Annoying - Mail goes offline for no particular reason

    I've seen enough in these postings to know that there is a bug in Mail. My situation is that I have four e-mail accounts that come into Mail through one cable provider. I constantly have problems with the little triangles saying "Offline". I used to think that there was a conflict with Entourage (which I use for a fifth work account) but now it is happening when I don't have Entourage running. I can quit Mail and re-open that fixes it for awhile. SOmetimes it doesn't happen for three days, and then sometimes four times in an hour (like today which is why I'm writing this)
    I do have a wireless connection. Could that be part of it?
    THanks
    PB G4   Mac OS X (10.4.7)  

    I am having a recent spate of the same activity... am running OS 10.3.9 and Mail 1.3.11. I too am connecting via a wireless Lynksys router on an open network which has NOT been changed in any way.
    First time this arose arose was just 4 days ago, and what seemed to 'fix' it for a time was to take mailboxes offline (even though Mail indicated they were all still online) and then go back online again.
    Then two days ago, and doing that fix only worked after several attempts over a period of hours.
    Today, it is resisting all attempts.
    When I do a mail check, the mail client's 'progress area' (the grey horizontal band) quickly reports connecting to the server, or even the authenticating step, but then stops and 'chimes' (that there is no new mail found). Checking webmail, of course, I see tons of mail waiting for me to come collect it.
    I wonder if we have a bug here, given our synchronistic experience of symptoms. Also wondering if Mail is mad at me for having so much stuff in there...

  • N79 Freeze often for no reason

    Hello All,
           I am using N79 for past one month. From the day one I am facing lots of problem with it. Previously I was using 6630. Which was much better in performance that N79.
           My phone gets frozen often for no particular reasons. Mostly I noticed while trying to use WLAN (Both secured and non secured). Photo applications and some while accessing the contacts to make calls.
          Only way to recover of this issue to remove the battery and restart the phone. No other way........
          It really hurts me to do so..... I have hardly used this when I was using 6630.....
          On average atleast I am facing this problem 2days once. 
          My firmware is up today. (11.049)
         Please somebody reply me.....

    Well I reply to you
    I take a part that you bought this phone I have it too. Nokia has forgot their old users and they don't have any solutions for you to freezing problems or allmost any your problem with your phone. The N79's firmware is very buggy and slow to use and many have found that too
    Go check this out: /discussions/board/message?board.id=swupdate&thread.id=48716
    Check this too: /discussions/board/message?board.id=smartphones&thread.id=136744
    And this: /discussions/board/message?board.id=smartphones&thread.id=136502
    You can help to improve Nokia's support for N79 by spamming their feedback inbox with your bugreports.
    So did you get my point? Or did this help you? I hope so.
    ps. I realy don't know why or where Nokia failed their stragedy (example flahship phone N96 took like a year to be like it sholud be(they released last week after looooong time new firmware to N96)). Doing this kind a **bleep** lose customers faith to Nokia.
    pps. I hope we getupdate to N79 soon, but I think it is useless.

  • Forms page opens very slowly for single user

    Hi ,
    We have a user in our EBS environment names OPERATIONS under which all scheduled custom concurrent programs run.
    The problem is it takes a long time just to open the forms page when I login as operations user , but when i login via other users such as sysadmin, the forms page opens very quickly.
    Any particular reason for it ?
    EBS 11.5.10.2
    DB 11.2.0.2
    Thanks
    Vicky

    Hi,
    One reason which i can see is:
    Since you said all the concurrent programs are running under this user name, I presume MOAC. is set for all the Org's for this user and as a result when the form is opened it has to fetch data for all the Org's for this users, whereas for other users it might be fetching data only few Org's.
    How to confirm this:
    1. Please enable the FND:Debug log for this users and check the data for MOAC assignment.
    2. Repeat the same steps for a different user and compare the Org's initialized.
    Hope it helps!!

    Since loading Lion, I've experienced much more instability than Snow Leopard. In particular, Mail crashes with regularity, full-screen apps seem to run slower and show the beach ball more often for longer, etc. I love the features, but I'm disappointed with the performance. Any help coming from Apple?  I've been sending them so many reports after crashes, that their file must be full!

    Summoning max. courage, I did what you advised. Here is the result. What does this tell you? My Lion 7.2 (mid 2011 iMac) has several annoying glitches (which I have so far tolerated through gritted teeth) but none that have actually stopped me working.
    BTW, I see several items involving CleanMyMac which I did not know I had. It is generally villified as a trouble-maker. Spotlight can't find an app. or a utility of that name. How can I get rid of what's there please? Just delete?
