My Old Mac Pro Dual 2.6 has an intermittent boot up failure.

 

It ends up giving me the "curtain of death" after trying to boot up..The grey curtain comes down from the screen top and tells me I have to restart.

 

I've pulled extra ram, removed hard drives, run Disk Utilities and been able to boot up with a my old install disk and run a file check on the HD and it shows the drive needs no repairs.

 

I've changed the Pram Battery and zapped it a few times too.

 

After running the install disk utility..it usually starts up and runs fine without locking up. But as soon as I power down and restart using the HD...the "curtain of death" falls once again.

 

The display screen whoch used to be white...now has some weird pattern under it too and is not pure white anymore.

 

I've taken out the video card and cleaned it off to get rid of any dust inside if that may have caused th problem.  It didn't fix it.

 

Ideas/ Suggestions???

 

 

Ideas, suggestions?


Mac Pro, Mac OS X (10.7.5), 12 Gig Ram, 3.5 GigHD's Bluetooth/A

    Can you boot it in safe mode?

    Not consistently.

    I re-laid the original OSX while I could to eliminate start-up conflicts.

    After a new OSX, it started up once ...and then gave me the screen of death when I restarted it after the new OS.

     

    I'm wondering if it could be a power supply problem?

     

    As I mentioned, thru the while issue, when I can run disk utility...the HD comes up fine.

    idd you do nit say what gpu and maybe that would help

    amazon has excellent 2x2GB FBDIMM $29

    I would not trust okder ram at all

    zero your drive or a new one before install

    go back to 10.6.8 for testing

    disk utility from recovery?

    cloned your system?

    I now cannot even get the MacPro to boot with the original OSX Disk.

    It freezes on a "Split Apple Screen"...with the Apple Logo and statrup timer split vertically and frozen.

    If you can see the image I am trying to post..it shows this effect and you can also see the  weird squiggling lines in the background across the screen too.

    I'm guessing it could be a video card failure. It gets pretty warm to the touch after a few start-up tries.

    If I ever get it started again, I'll try and pull the panic codes from the log.

     

    Any other ideas? Won't start from an external drive either.

    I don't see how that can be anything but a bad GPU or some other hardware fault. Check that the display cable is securely connected.

    Linc...agree 100%.

    It's not acting like a Mac anymore...won't even take a PRAM reset.

    I've tried a lot of other "fixes" swapping/pulling Ram, changing startup drives, relaying OSX on an external drive.

    I think it's gone.

    Luckily I was able to get all my critical files off the various HD's which now live in my new Mac Pro.

     

    I've never seen the "Split Apple" before.

    Happening consistently now.

    a Bad graphics card has been known to keep a mac from being able to boot properly, and can certainly cause kernel panics.

     

    What graphics card is installed?

    It's the base card that the early Mac Pro's shipped with back in 2006 I believe..the original. I pulled it out and there was no name on it other than serial numbers and "Made in China". I reseated it, rebooted with the original System DVD and got the split Apple Freeze Screen again.

    The Apple-firmware 5770 is a nice upgrade for any Mac Pro running 10.6.5 or later. About US$250, it works in every model Mac Pro, but may have "anomalies" when playing copy-protected Videos.

    Nvidia GeForce 7300.

    "Massaged" it to startup with the original OSX disk, passed it's disk utilities on the internal HD. Restarted with "D" to run diagnostics, and it found everything OK. Running the test suites now. It's locked up before during this...I'll see what happens.

    I've run everything from the original sratup system disk before..it's reported no issues and when I've rebooted with the HD DSystem, that just passed disk utilities as being fine, not needing any repairs, it's frozen. At least I got past the Split Apple Screen enough to double check everything tonight.
