    Final Cut Pro 7 has been continually crashing on me, citing my graphics card as the reason. I also get lots of "out of memory" errors, when I have plenty of hard drive space, free RAM, and relatively simple sequences. I doubt that my graphics card is the real problem because I just got a new one in November. I've been editing high res video files on this computer for almost 4 years with no problems until now. I tried to use Disk Utility but the "Repair Disk" button is grayed out so I tried "Verify Disk" but it says that my disk is corrupt and cannot be verified. I've read postings that say to start up my computer with the installation disk, but I no longer have it. Any thoughts? Should I try upgrading to Lion? I'm just hesitant to do that because I'll probably end up replacing this computer soon anyway.

    Computer specs:
    15" MacBook Pro ~2008
    2.5 GHz Intel Core 2 Duo
    4 GB RAM
    Graphics Card: NVIDIA GeForce 8600M GT

    You'll need another tool if Disk Utility can't fix it. I'd recommend DiskWarrior from Alsoft, I've used it for years with good success.

    I use Disk Warrior as well. Works great for fixing corrupt disks and recovering broken file directories.

    That said, if you have this corruption issue a lot (or this computer is important for work), I'd consider getting a replacement drive.

    Do you have a OS X that you can use to boot to Disk Utility? I had the same problem that you did and AFAIK you cannot repair the boot disk while it is being used. You need to use a bootable OS X DVD or USB to repair the disk. I was able to repair my disk and it has been working fine ever since for over a year.

    The OP said he didn't have a bootable disk.

    OP, you might be able to get one from apple. I wouldn't try to upgrade to Lion with a corrupt disk though; that just sounds like a recipe for disaster...

    When Disk Utility's attempted repair screwed up my disk royally, I tried a number of things, and what finally worked was fsck_hfs. Unfortunately, I can't remember what options I used, and I think I needed to boot from my install DVD.

    I had this same problem once on my MacBook. The only way I could fix it was by erasing the HD, and reinstalling the OS with a disc. I'm pretty sure someone has the disc on eBay OR you can buy a new one from Apple. I'm not really sure if installing Lion will help the problem.
