Welcome to Discussions - Please make sure that you have a bootable clone as soon as possible, your internal drive is failing and you will lose all your data.
If your computer is only three years old, it's an intel, but the same instructions apply - back up!!!
You can try running Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.
and/or the Apple Hardware Test, also on your install disk to pinpoint your problem. If you have access to Diskwarrior, that would be a good tool to use.
If you have AppleCare, call them, since you should still be covered if the machine is less than three years old.
Please post back with results,
Ok here's an update:
I followed the steps you said and briefly wrote down notes of error messages, whilst verifying the HD I received the following;
Incorrect number of thread records
Invalid leaf number count
Invalid volume file count
The volume Macintosh Hd needs to be repaired.
ERROR: filesystem verify or repair failed
This was self explanatory So i continued and begun the repair disk.
Error messages were as follows;
checking catalogue hierarchy
missing thread record
invalid directory count
should be 0 not 7
missing thread record
" " "
A series of these messages came up with other saying it should be
0 not 25,
0 not 26
It then said Invalid node structure
Volume check failed
This took around an hour and 20 minutes too complete the checks,
I attempted to try this again after some sleep but the HD wasn't always appearing as an option to scan, just the install disc and a local network.
I will continue to attempt this and shall post any more updates asap,
as for now I've managed to log on my user fine and so far so good....
hopefully the details posted may mean something to you, to me it tells me something is wrong and that is as far as I know
DiskWarrior or Drive Genius or TechToolPro can repair your corrupted directory, but here's a rather convoluted way to do it if you can actually boot from your internal drive and don't have access to one of those basic, valuable tools: [http://hints.macworld.com/article.php?story=20070204134513557]
You might also take a look at Dr Smoke's Resolving Kernel Panics, there may be something of help there.
Since the disk repair that supposedly failed to complete, the computer has been performing much more consistent, now only having the slight crash here and there. I did perform another check in disk utility and both the verify and repair of the hardrive stated they were working fine, maybe problem gone for a little bit?
I will do the steps you just posted and hopefully I'll be running 100% again
If this is this case, I can't say how grateful I am for the help! if this question is marked as solved will this close this thread? I think it may be more helpful to leave it open? The advice helped me, I'm sure someone else is looking for info on the same topic somewhere, so leaving it open would make sense?
