Boot Fail, Kernel Panic all the time.

My Mac Pro early 2008 does not start I have constantly to the kernel with the usual panic ""you must restart your computer. " Hold down the Power button for a few seconds or press the restart... in 4 languages.

Start Up Manager all my Bootable drive are there. I tried different elements Bootable. But all end up with the kernel panic. I even try to start with my Lion drive install, same result. I also try it in safe mode, once more: KP.

My machine came with 2 GB of Ram, I add extra 4 GB (pair of 2) so I have 6 GB. I thought that my problem is Ram so I pulled out the pair of 4 GB, but it does nothing and I always K.P.

Can someone let me know if it's my graphic video card? Unfortunately, I live on an island in the South Pacific: no serious Service Apple around.

Thank you.

Mac Pro early 2008. 4 Bay, 4 total 3500GB HD. OS x 10.6.8 - 10.8 - EL Capitan - every operating system is in an another HD 6 GB of RAM.  The machine works very well so far. !


I forgot to add that I did reset the PRAM and SMC but it's always K.P.

  • GeForce 7350LE graphics card fan is running all the time or at certain temperatures?

    I have a HP Pavilion m8147c Media Center with AMD Atlon 64 X 2 Dual Core processor 5600 + 2.80 GHz 3 GB of Ram and run these last time the parser when began to enter the mode "sleep" or something. Sometimes, there is a warning that says something like no signal DVI and one more, but still not long enough to read all this. I am running Vista Home Premium 32 bit. I had just installed a new game but enough course has nothing to do with that I used the system restore and backed up to a time before it was installed. At the beginning it was only when you play, but now, it happens with almost nothing running. This pc was purchased in July 2007 and I have another office but I let my wife use one and I use the other. I opened the folder and clean all the dust but noticed when I booted again that the fan does not work on the video card. I don't know if it lights at certain times or works all the time but I think that's the problem. He was about one hour and lights do not at all. Any information will be appreciated.

    captna wrote: thanks again for the help, I thought it was probably the case but never bothered with graphics cards before today. Any thoughts on an upgrade for not much more money? It was a pretty good pc when I bought it, but it is old, and there should be some video cards better for the same price that would work. I'll add some memory and while I am because the grandchildren need to play their games too. Do you know where to find an upgrade that would be compatible? Yet once again, I appreciate the help.

    Hello captna, here is a link for the specifications of your system. It shows that the system was delivered with a 300 Watt power supply.

    There is not much better performing video cards that work with a 300 Watt power supply. Most require at least a 400 Watt power supply or greater power.

    You could improve the feed and the video card, then possibly 4 new memory modules, but the cost would start to add up. On a system to make a few years about it, I don't know if this would be the way to go, or consider getting a new system.

    You could simply acquire a new video of the same type card and get the system back, because there was, or even try and find a graphics card fan to replace the failed fan. It would be the least expensive option.

    Your system was shipped with the memory 3 X 1 GB modules. It only supports 4 X 1 memory modules, so upgrading the memory would not help all that much. You'd probably remove the existing memory and install 4 new memory modules in order to be compatible with your system memory. It is not recommended to mix memory strips.

    Just some thoughts.

  • radio station, playing all the time

    Hello billyepat,

    I see that you have problems with a radio station on your computer and you cannot shut it down. I have some suggestions that can help with this question.

  • Pages crashing all the time after updating the OS 10.11.3

    Hello, I have problems with Pages crashing since I received the update OS X El Capitan (10.11.3). Common problems are:

    • Pages could open documents with considerable delays: when I double click on a file, it may take up to 20 seconds before opening the document (at the same time, the only thing running is 2 tabs in Safari with non-intensive websites like Wikipedia);
    • Pages would not open to all documents: sometimes it refuses to open my documents either. When I choose for example a document on the 'Recent' via dock icon Pages list it will not launch it. If I wait for awhile and just click the Pages icon, hoping that it will be launched the document in the background, he brings just to the top of the window with the models as if I wanted to open a new document.
    • 'Missing font"all the time: I did not the latest changes to my fonts, but when I opened a document originally created in Pages (and not a converted copy of an old Word document) it always gives an error message "missing fonts" - particularly associated with Microsoft fonts. I downloaded and installed Cambria and Calibri manually and it fixed the problem... for about 8 hours, then he started again.
    • Beach ball rotation of death during the execution of simple operations: it's exasperating, but every now and then when trying to type or text in bold (and similar), the beach of death ball will appear, making the Pages does not.
    • Crashing before loading the same: when I force quit the app because it did not and then I try to run again, often they no longer again before loading the same. What the...?
    • Impossible to duplicate documents: at one time I thought that it is a certain file at the origin of all evil, so I tried it duplicate several times - which of course caused Pages to plant again and again. Same thing happened when I tried with other files.

    I had a similar problem before and it was fixed to restore the default fonts and removing duplicates in the FontBook app, but unfortunately it did not this time.

    I don't know what is wrong or why. It was working OK just a couple of days. Anyone else have similar experiences with it? Looks like Apple may not come out with an update that doesn't break the workflow of the people. But yay, more emoticons and pictures Live Webcam on the way!

    Because my Pages on El Capitan 10.11.3 v5.6.1 works very well with any of your questions, I believe that it is not Pages, but something out of Pages in your environment operating system as a cache of corrupt police, duplicate fonts, or damaged preferences file. Perhaps it is that you are too many applications running for your memory availability and Pages of hunger. All in due time.

    Let's start with a secure boot that will clear the system and local caches, rebuild the database of the police and then see if it stabilizes your use of the Pages.

    Secure boot

    1. Shut down your Mac.
    2. Press the power button and immediately press on and hold down the SHIFT key until you see the horizontal progress bar. I usually wait until it's an inch along before I release the SHIFT key. Personal touch.
    3. You will arrive at a login window. In the upper right screen, you'll see Safe Boot in red letters.
      1. After you type your password, stop, then press and hold the SHIFT key again once, before you click on the right arrow to open a session.
      2. Continue to hold the SHIFT key until your painting of icons on the desktop.
      3. Because many drivers are not loaded, graphics performance is not optimal, and may feel morose.
    4. Test Pages in startup mode to see if the problems have disappeared.
    5. Restart normally.
    6. Start Pages and open a document.

    Previous post the results of step 4 and 6. Have what improvements (if any) you noticed?

    Can you help me?

    Hi Henrik,

    The hinges of friction on the lid of your laptop computer failed, and therefore the lid will not stay in open position. It is unlikely that you will be able to get the new hinges, otherwise a Toshiba authorized service agent, then I'd say that your best course of action is to contact your nearest ASP and ask for a quote to replace the hinges.

  • Upgrade to Win 8.1 the fan runs all the time and Raw (Silkypix) converter consume 100% CPU resources

    Hi, after upgrading to win 8 to 8.1 win my converter (Silkypix) raw program running extremely slow and consuming 100% of CPU. VAIO all updates completed, all Win 8.1 updates made. ATM Radeon HD 7500 M / 7600M (Maj) with 2 GB RAM dedicated.

    In addition, the fan works almost all the time that was not the case with Win 8.

    Vaio SVE1712Z1EB with 8 GB of RAM, i7 processor execution.

    SeanQ, after some time looking for a solution I finally found it on one of the vaio sites forum: it is the Radeon driver that must be installed from the Vaio support site. NOT the driver the latest AMD site. It does not solve the problem.

    I did as follows: device, graphics card, Uninstall Manager. Did not help. Went to AMD in Program files. Setup.exe has begun, but instead of installation, clicked on uninstall. In this way, I uninstalled the driver former AMD and bad news from the site of AMD. I had to manually uninstall the driver in Device Manager, several times. Finally, I went to the site of Vaio and tried updating the driver. He failed. Reset. Manually start the update of the Vaio AMD driver. Finally it worked.

    The fan is now more or less normal speed.

    Overall, I spent 15 hours looking for this solution. How much is my time worth? Just joking, I'm happy that I found the solution.

    Does anyone know what is causing the "debug" window pop up and how can I stop from occurring?

    Thank you very much


    Hi Donna,.

    We will see if it is caused by something starting at startup or with some drivers.

    Try a boot minimum  If the problem goes away then it's just a matter of tracking down the culprit at the origin of the problem.   Follow the procedures described in the article.  Once found, remove, delete, disable or uninstall.  Once remember to put Vista in normal status, as described in the procedures. If the problem occurs in clean mode then just restore the system to normal and reboot - this solution will not work.

    Start in safe mode with network and see if the problem is here.  A result allows us to narrow down the search for the cause.

    I hope this helps.

    Good luck!
