The omly disk that came with this machine are an i work 08 install disk, an Apple pro-training, an aperture install and an applecare protection plan disk. Is it one of these?
No, its Apple Restore Disk which have a grey color like this;

We may need the disks to repair your Mac. If you don't have that disk with your Mac, contact Apple and they will give it you. Now try the following troubleshooting steps;

Run Disk Utility in Single User Mode :
Turn it back on and this time hold down the Command (Apple) key and the S keys at the same time. Then type the following command...

/sbin/fsck -fy (note the space between fsck and -fy)

If you can't run /sbin/fsk - fy then type only fsk - fy

Hit return and the disk utility should run and let it finish. When it finishes and there is no error, then type in reboot and hit return. Let the Mac boot up and see if it is still giving you problems.
