OSX.4.9-Sometimes can't wake-up, other times freezes on log-in window

I have an iMac G5 1.8 ghz with 768GB ram. This problem has been going on for a few weeks. The last update installed was SecUpd2007-005Ti.pkg on 5-26-07.
When you try to wake the computer, sometimes all you get is the notorious beach ball and a gray screen. When that happens, you can press the power button on back and it will cut off then you can cut it back on and get the login window. Sometimes you can then login okay but sometimes, as twice last night and once this a.m., it will gray out and freeze after typing in the proper password. This morning, I typed in password on login from sleep window, it grayed out and stayed that way with the beach ball. Then the screen went black and the CPU fan took off, really loud. I had to unplug the computer and reboot (pressing rear power button didn't do anything). After reboot, I was able to login fine. A crash window for report to Apple appeared and I sent report. I have disabled sleep mode for CPU and checked only display in System preferences until I can get this bug worked out. I also have reset nvram but that didn't help. I'm pretty adept at solving my own problems but this one has me stumped. It acts as if it's a system problem. Any ideas on what it is?

Update:
Ran Hardware test. All components passed. I disabled all password required options except, of course, on restart. I have set the display to sleep after 1 hr., the screensaver after 15 min. When I wiggle mouse or touch any key, I now get desktop. Okay, that said, when you login from sleep, the OS is very unstable, applications are slow, sometimes even the dock isn't accessable and eventually, the OS crashes. When I restart, the logging in from the restart users login window, no problems! Everything is fine. So, what's causing the computer to not wake from sleep and on the rare occasion when it does wake, the OS and applications are unstable? Is this a 'firmware' problem or is there any corrupt start-up files I can trash and replace? I can copy over files from my other computer with same OS and replace, if need be.

    You need to give a lot more information about the media specifications and the project properties you're using in the different projects.

    The utility has had less and less useful information .. it might be time to simply find a different utility.

    This is very popular.. I do not know of what works well on Mac OS because i have installed 5.6 utility which of course has far more info than the later toy version. Plus using an Asus router which has excellent listing of all the clients.
    Sometimes beating yourself up to make apple routers do what you want is easier solved with lateral thinking.

    Hi everybody. I'm a happy mac user sinc 2001, and i have since 2004 an ibook G4 800mhz. Ok, everything good, the problem is that from today if i leave the ibook in stop mode for half an hour for exemple it can't wake up, everything seems dead and i have to push the power button for 4 second and then turn the computer on again. If the sleep mode duration is about 5 minutes ok, otherwise it can't wake up. whyy???? what is the problem? i reset pram, nvram and pmu, but nothing. everything else works perfectly, but this is a very important problem for me because i risk to lose my work because i have always to reboot the system.
    Pleas help me!!!
    Ps i'm sorry for english, but i'm italian...
    thanks a lot

    annihilator,
    Quoting from my own post:
    ""It could be a PMU problem. The PMU is actually a tiny computer within the computer. It's official designation is PMU99.
    http://developer.apple.com/documentation/Hardware/DeveloperNotes/Macintosh_CPUs-G4/12inchPowerBookG4/2_Architecture/chapter_3_section4.html
    "Power Control IC
    The power manager IC in the 12-inch PowerBook G4 is a Mitsubishi M16C/62F microprocessor, also called the PMU99. It operates with its own RAM and ROM. The functions of the PMU99 include:
    *controlling the sleep and power on and off sequences<</div>
    *real time clock
    *controlling power to the other ICs
    *monitoring the battery charge level
    *controlling battery charging
    *supporting the interface to the built-in keyboard (AND TRACK PAD)
    The PMU99 also provides the hardware interface to the keyboard. Software in the PMU99 IC scans the keyboard, then sends the data to the system in packets like those from the ADB. To the system, the keyboard behaves as if they were ADB devices""
    Try resetting it:
    http://docs.info.apple.com/article.html?artnum=14449
    If that doesn't work try what I call a deep PMU reset.
    Pull all power including the battery, push the power button to remove residual charge in soft start capacitors.
    Then walk away from it for at least 10 hours.
    This has worked for Macs with the PMU99 since the G3 Desktops and especially the G4 Towers (Sawtooth, GI, MD, etc)
    Also:
    i had a problem with trackpad that became crazy, but i unmount it from the case i clean it and now it works better than perfecty.
    Could you explain this more clearly? You opened up the iBook, then
    i unmount it from the case
    so you removed the trackpad part itself from the upper case? the trackpad part and associated circuitry? Was it glued to the upper case? in that kind of little well it sits in? But you didn't break the plastic welds that hold the "clicker" part to the upper case?
    i clean it and now it works better than perfecty.
    Which part was dirty?

  • Ok- I might need to be a bit more specific-- My MacBook Pro is suddenly making a whirling noise-- sometimes it's quiet but other times you can really hear it from across the room.  This just started happening-- it almost sounds like a tweeting noise --

    I submitted a question last night but wasn't specific enough-- My MacBook Pro is suddenly making a whirling noise when it's on.  Sometimes it's  not too loud-- but other times it almost sounds like a tweeting--  there is nothing in the DVD/CD drive--   Is this something I should have looked at?

    This is not normal. It is better to have it checked. Take it to the Apple Store.
    Best.

  • Email sometimes only in  All mail other times normal mailbox..same sender

    Can anyone solve this dilemma ... sometimes an email will go into ALL Mail and other times the email from the same sender will appear in the normal email inbox.. very annoying... the only way I know the email is there if I am checking on my macbook or Ipad... only happens on Iphone.. any ideas

    According to the gmail support, the All Mail folder is where you archive your mail when you try to delete from the Inbox. Does this address what you are asking?
    No, the "All Mail" also shows the contents of the inbox, sent mail, and archived (trashed) mail when viewed in the Gmail App.  In the iOS Mail Gmail account, what shows in the All Mail folder is random.

    It happens with many sites on a daily basis and is so annoying that I'm considering going back to Explorer. Sometimes the site appears and so does the box (sometimes with multiple boxes and I must delete each one before I can continue. On other occasions I'm blocked and cannot open the page

    * "Clear the Cache": Tools > Options > Advanced > Network > Offline Storage (Cache): "Clear Now"
    * "Remove the Cookies" from sites that cause problems: Tools > Options > Privacy > Cookies: "Show Cookies"
    Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
    * Don't make any changes on the Safe mode start window.
    See:
    * [[Troubleshooting extensions and themes]]
    * [[Troubleshooting plugins]]
    If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
    * Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
    * Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

  • Mail will send sometimes and won't send other times

    Hello,
    Our mail in our whole office with sometimes send out using our pop account, and then other times the recipient will just never receive it. We get no warning if the mail was never delivered we just find out a week later that so and so never got our email. It has worked fine for years, now all of a sudden it variates.
    Getting mail has never been an issue, only send (sometimes)

    Need more information - way more.
    For example, does the problem affect ALL mail at a certain time (e.g. all messages sent to any user fail) or does it only fail for some messages?
    Does the problem affect particular recipient addresses or domains? or does it affect everyone regardless of email address.
    What do the mail logs have to say about it? Do the logs indicate that the message was sent? or that there was some error?

  • How come sometimes I can load FB and other times I get the "this is a not trusted site?"

    Sometimes I can get right into FB, this also happens on Internet explorer. And sometimes I get the not a trusted site message. If it is happening on Firefox it will also be on IE and Goggle at the same time. Sometimes I get into FB then cannot contact to Farmville. Yet 5 minutes later I can get in. Very,Very frustrating. Any answers out there?

    There are two things to check.
    * Check your system clock.
    Sometimes the clock / date is wrong, and causes problems like this. Open
    your clock (normally you right click its icon). Go thru its menus to check for
    the correct time, and time zone. Also, make sure that the option to
    '''Synchronizing with an Internet time server''' is turned on.
    Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
    You can try these free programs to scan for malware, which work with your existing antivirus software:

  • Why is ask to share someone screen greyed out when on yosemite, sometimes it is greyed out, other times it's not

    can someone tell me when I try to screen share and ask if she will let me see her screen, the option to ask to screen share is greyed out.  The weird thing, is, is sometimes, it's greyed out, and sometimes it's black.  Can not figure out why that would be.  Tried same thing with my Bro and the option was not greyed out.
    Is there a glitch or what when its inconsistent about the option to ask to share their screen.

    The quick answer is that certain Back to My Mac features are not working well in Yosemite.
    Read some of the following to determine if there is anything you can do about it, otherwise we will just have to wait for Apple to fix it:
    Setting up and using Back to My Mac with an AirPort base station or Time Capsule
    OS X Yosemite: Share your screen using Back to My Mac
    If you have issues using Back to My Mac - Apple Support

  • Images are sometimes saved under original name, other times, under name url.*

    After recent update to FF 23 I have a problem with saving image files. Whenever I drag and drop the image from page to desktop (Explorer) or if I open the image page and press Ctrl+S, I get image file names (most of the times) url.jpg or url.gif or url.png, etc.
    Sometimes the filename matches original image name, but mainly it is url.*
    I have several extensions installed, but they were installed on previous FF versions and did not cause the problem. (Ghostery, AdBlockPlus, FireBug, etc.) Turning extensions off does not seem to make any effect.
    In about:config I have "browser.download.lastDir.savePerSite" set to "false".

    I have been doing some digging on my account.  I have right clicked on the offending songs (which is about 1 in 25 or so) and then clicked on the sort tab and found that the data is all jumbled -- title and artist start out as incorrect but then I play the song and it corrects itself.  On the "Get Info" tab the artist and song are listed correctly but the sorting information is incorrect (not surprising -- right?).  I read somewhere that it might have to do with duplicate songs and to delete the duplicates.  I have not deleted anything yet and am still diagnosing but I feel like I have a better handle on it.
    There is one album that seems to be causing real problems and gave me a big hint.  There are three tracks for each song.  One track was one I purchased under an old Apple ID in 2009.  In 2012, I bought a new macbook and set up the itunes library and this duplicate track is listed as being purchased in 2012, as well.  All the other older songs that are not having problems have the Nov 2012 date instead of the original purchase date.  the third track is the one that is misnamed and then changes to the real song title when I click on play but the sort order is still an issue.  Did you happen to get a new computer recently?
