    Hello, Thanks in advanced for the much needed help!

    Mac Pro 3.0 GHz 8 Core 16 GB Ram 2 500 GBs (Dual-Quad) 2,1 8CX ATI Radeon X1900X running lion 10.7
    Purchased used from Ebay 3 years ago.

    A few days ago I have not been able to get my Mac Pro past the White loading screen with apple logo, loading spinner, and for a few seconds a loading bar beneath that goes away that Ive never noticed before.

    Something that has been occurring that I have been ignoring for a while are also that my monitor only activates every few times I turn on the Mac Pro, so I have been doing a lot of force shut downs to use the Mac.

    I have been unable to boot to safe mode, I can boot into Recovery mode, and startup manager.
    In recovery, I have tried Disk Utility, on both verify and repair of my main drive I receive the message "Rebuilding Catalog B tree. Keys out of order." I receive the same when running "fcsk" each time.

    I have 3 internal hard drives, the main drive which i receive the error messages on disk utility. A storage 500gb western digital HD and a 1 tb drive preinstalled with music software.

    I recently bought a thumb drive with bootable Yosemite 10.5.5 to try to boot from and no luck, the Mac still is stuck on the same loading screen as when I try to boot normally. I also tried to reinstall Lion on the storage drive however receive the error message "this item is temporarily unavailable" after using my apple ID, I assume because it is the Apple ID that was used to install Lion originally.

    Any ideas? I am considering trying disk warrior. I have been using this Mac to compose music for a local film and need my data and software pretty soon.

    I would greatly appreciate your alls help!

    may very well be bad X1900, they usually start doing black screens then go out

    Firewire in with it gone or put your drive in an enclosure

    Is it possible the bad video card is preventing the Mac from booting at all?
    What would I firewire it to? and what is putting the drive in enclosure?

    Thanks for the reply
