Mac Pro Intel of dead money and does not start flashes and clicks

I have an old Silver Mac Pro that I use for a disk hard/servers in the farm. Yesterday, that click on it all of a sudden off the coast. It is on after power up. So now he's doing the following:

It snaps, white light, he snaps, white light goes back off the coast.

If I disconnect, reconnect it, and then press the light button turns with a simple click and clicks right back off again.

I think power but would like advice.

Thank you

    Hello mpm068,

    Thank you for using communities of Apple Support.

    Since your iSight webcam works up to the time that your Mac goes to sleep, I would like you to start please help desk trying to replicate this problem then to reboot in safe mode:

    1. Choose the Apple menu > shut down.

    2. After your Mac stops, wait 10 seconds, then press the power button.

    3. As soon as you hear the startup tone, hold down the SHIFT key.

      You must press the SHIFT key as soon as possible once you hear the startup tone, but not before.

    4. Release the SHIFT key when you see the gray Apple logo and progress indicator.

    To exit safe mode, restart your Mac, but no press during the startup.

  • Thunderbird Setup does not start by double clicking on

    Downloaded Setup for Thunderbird 31.4.0
    Double-click the installer does not start the installation program (even if a process is created as seen in Task Manager).
    The reason for downloading the installation program has been that the automatic update failed to 31.3.0 and asked me to download the installer.

    Platform: Windows 8.1

    I tried as admin and also disabling the AV/Firewall.

    A reboot solved the problem and I was able to run the installer and install 31.4.0 after the restart. However there is a thunderbird called "Software Update" window that displays a progress bar and says "Download update" & "Connecting to the update server" - but it seems to be stuck there forever.

    I killed the process of updating the software and the system now seems to be at peace.

    Thanks for the help!

    It's very strange!
    Have you removed any spyware or Trojans?

    Question you is really, really strange, and I guess that the 'bad' software causes such problems...
    It seems that something changes that replaces Userinit.exe.

    It seems that some registry have changed and that's why the connection does not work correctly!

  • Mac OSX Lion in ESX 5.1 does not start

    Hello

    I have a virtual machine to work in "VMWare Workstation 8.x" with Mac OSX Lion (I corrected my computer to do).

    I converted this virtual machine with VMWare Converter Standalone 5.1.x in vSphere ESX 5.1 and, after the successful conversion, I properly configure the type of operating system like Mac OS Lion.

    In ESX, the virtual machine starts, but stuck with the Apple logo and the spinning wheel of progress. So my questions are:

    • Do you have advice on how to fix this?
    • How to enter in "verbose" mode in vSphere? I tried to delay the start and be ready to press the two 'CTRL + v' or 'WIN + v' or 'ALT + v', but nothing has worked.

    Thank you!

    Eddie C.

    The problem here is that you violate Apple's EULA, no one here will be able to help since it is breaking this rules of communities.

    To virtualize OS x, you must run on Apple hardware.

  • Firefox does not start when I click on its icon. As far as I can see, all the program files are present.

    Firefox functioned perfectly earlier today. Tonight, when I tried to start Firefox as I usually do by clicking its icon in the quick start of Windows 7 bar there is no frequency. The same thing happens when I click on the application icon in Windows Firefox program folder. Is some way this can be fixed easily?

    I ran a full scan with Norton 360, Malawarebytes and Iobit Malware Fighter, whose no is no problem. Also, I checked the settings of Norton 360 and found no problem with the settings of Firefox. I downloaded the Firefox installation files and ran a custom implemented, by clicking on upgrade. Firefox now works well with all the Add-ons, bookmarks, history, cookies and saved passwords intact.

  • PS does not start on double click on a thumbnail in BR

    I face a very recent problem:

    Since 2 days I can't open a picture in SP6 by double-clicking on the thumbnail in BR.
    The right-button-Petite shows 'open with': FireFox, / Mic.Office Pict. Manager / paint / Thunderbird.  But no PS!

    Can someone give me a hint to change the right-button-Petite?

    I know, there's a shortcut, but I'm used to the doubleclicking, which is the most comfortable way.

    Thanks for the replies

  • Defective video on Mac Pro Intel card?, help!

    Hi all, my Mac Pro Intel crashed at recentpy. At the start, it appears that the SSD drive had failed completely. Since I replaced the drive however at startup, I now feared vertical lines. What is a graphics card problem? I have tested the monitor and it works fine on other machines. The machine hangs at startup and I tried a number of different ways starting in diagnostics etc. The video in the machine card is a Geforce.

    Sounds very like the graphics card has disappeared.

    which he was.

  • CS LR6 of CS LR5 update does not start

    Hi, I have just install CS LR6 by buying the upgrade. Everything seems fine with the process (from download to install), but LR6 does not start when I click on it.

    I've only had this open window: '

    Capture d’écran 2015-04-21 à 22.04.57.png

    Translated, that means, there is a problem with my setup (I don't think while I used LR fair, 5 five minutes ago no problem) and that I should try to uninstall and reinstall... I can't uninstall uninstall link is too broken.

    Any help would be welcome.

    Stone

    OK got it working, but I had to delete all the files Adobe virtually any Mac application, kept only some newspapers (I thought it can't hurt and I'm tired of this mess) and then do a clean installation/configuration in this order:

    -Install the creative cloud with the CreativeCloudInstaller.dmg downloaded from Adobe

    -Disconnect of the CC of the preferences panel and leave CC (after a while of waiting for the "Exit" option to be available on the menu, don't know why).

    -Install Ligthroom 6 LS11 my purchase of upgrade .dmg Installer and download.

    -Launch LR and follow this way to serialized: using Adobe Photoshop Lightroom | Serialize Lightroom trial to activate like Lightroom 6 CC

    Now, I have to install PS CS6 back and all my plugins and settings.

    If you need to do to, be sure to have backups secure (several).

    This solution is really the only one that worked for me, because I think I've tried almost everything I see here (reconnection of the CC, restart, reinstall, delete files, give rights to libraries and so on).

    For the moment, everything is fine (I have no time to seek more internal LR6 bugs) and I got the standalone version works even without connection internet (I tried).

  • C870-19(r) satellite does not start with the new SSD

    Hello

    I will update the Toshiba Satellite C870 19(r) with a Pro 840 Samsung SSD, but it does not start.

    He said: not found system.

    Post edited by: joch333n

    None found system means that there is no system installed on the SSD drive...

    What you trying to do?
    You start from a disk in order to install the new system?

    In this case, you should disable startup secure in the BIOS.
    I also recommend moving from UEFI mode MSC!
