My Mac Pro (2006) has suddenly stopped sending signal to the display monitor. It coincided with plugging in an Epson printer via usb - while the system was running. Pretty dumb maybe? Could I have damaged the video card? Anyone ideas? Thanks

Mac Pro, Mac OS X (10.7), 2 x Intel Xeon Dual Core, 14GB RAM

    Howdy Le Batch,

     

    I was looking into the issue you are seeing here, and came across a helpful article for this specific situation. It's named Apple computers: Troubleshooting issues with video on internal or external displays and can be found here:

    When using an external display be sure to check the following:

    1. If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
    2. Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
    3. Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
    4. If more than one video adapter is in use—or "daisy-chained"—troubleshoot by using only one adapter.
      • Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
    5. If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).

    Reset the system
    You can reset the Mac's parameter RAM and SMC.Reset the resolutionStart by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:

    1. Start up in Safe Mode.
    2. From the Apple () menu, choose System Preferences.
    3. Choose Displays from the View menu to open the preferences pane.
    4. Select any resolution and refresh rate that your display supports.
    5. Restart your computer.

     

    Regards,

    Sterling

    Lion over Snow Leopard on a Mac Pro and lack of Rosetta, need for newer drivers and driver conflicts as well as some graphic cards no longer "fully" supported is not obvious to end users or in the Setup and Install process.

     

    If you have X1900 or OEM 7300GT, or if you have old drivers or just don't have the latest, that can cause trouble as well as a system carrying around extensions and drivers from "who knows when."

     

    I personally doubt it lies in resetting the SMC or other general support tip extracted from Apple support articles.

    The 2006 1,1 is 7 yrs old, won't take some new cards, won't run Mac OS beyond 10.7.5 (which is a good version).

     

    Being used did it come with OEM DVD? that has Apple Hardware Test.

     

    Are you familiar with mac system maintenance? Cloning? how to repair the disk directory? there is no thorough chkdsk command to check w/o buying 3rd party.

     

    The graphic cards from that era, and that were supported, are all iffy

     

    Upper left corner "Apple symbol" About This Mac.... More... System Profile... that will show memory, graphic card and more

     

    And you may need to replace or swap parts.

     

    But plugging in a printer to front or back USB ports (that is where you did so) is not an issue.

     

    If the system OS came PRE-INSTALLED wipe it clean and do your own install.

     

    You can also setup Windows but it is murder on this model to use, issues with 64-bit versions and even 32-bit, so I don't recommend it. Normally Windows on Mac works better (but this Mac it is not other than XP and Vista pre-SP1)

    Sounds like you know your way around and have all the tools and wherewithall - I would just add Carbon Copy Cloner to the mix if you aren't already doing so, it will clone and create Recovery partitions as well.

     

    Clean install from USB or other device (you can use a small hdd partition btw) - and THEN use TimeMachine to restore or migrate/setup (restore from TM is not a clean system is it).

     

     

    I would not put Windows on the current OS drive if you can avoid doing so and instead set it up on its own drive... first started on a PC with your old 128GB SSD, then sneaker net over to the Mac after the initial install off the DVD. Booting Windows 7 Pro or 8 64-bit is trouble on this model 1,1. Pro because you have dual processor, and if you don't use 64-bit it is crippled to using only 1.9GB RAM as well.

     

     

    Mount point?  you mean no underline named there? how was the SSD formatted? Odd.

     

    1. Install TRIM Enabler 2.x

     

    2. Make a disk image and clone to another hard drive partition of your Mac system on SSD

     

    3. Boot off the clone and run Disk Repair

     

    4. Disk Utility will trim the SSD

     

    5. It is possible you need to refomat the SSD and restore

     

    6. Do not write zeros to an SSD. 1's are safe.

     

     

    You can do a bit more and get more out of this Mac Pro, and wait out until even Pro Tools has had time to "catch up" to where Mac Pro and OS X will be in a year +.

     

    Yes, re-think. I am hoping for a Mac Pro under the Christmas tree to get out of some of the limitations - once the next OS has dropped and with it a couple of post-dot-zero release updates as well (no more beta for me).

    ok I have a mac pro 2006. I have just replace cpu,s and logic board. the display is not coming on im getting no signal from the video card. I got a used video card on line a 8800gt geforce at first it came on then the screen would become distorted. then i would kinda like see a checker board look, but when i replaced the logic board now in wont come up at all. it dosnt even get warm after awhile of running.so the problem is I see nothen it wont boot up in safe mode.Ive checked the leds i get the yellow trickle light on 1 and the green light on 7 I can hear the hard drive working and the opt drive works as well. ive tried reseting smc ive unplugged the power cord pressed the power button for 20 seconds and plugged the power back in and pressed the power button and held it in tell the little beep sounded and reset smc button as well.I feel like its the video card but want to make sure before buying a new one.not sure how I could set up a new hard drive with operating system and drivers with out having a screen.
