Hi jesse ...
You can try repairing your disk ..
(A) Boot from your Mac OS X Install Disc 1 CD or DVD. Put disc in drive, wait for it to show up on the desktop, then go to upper left of screen under the Apple menu and choose restart. Immediately hold the "c" key down until you see the apple logo.
(B) When the Installer window opens, select Installer > Disk Utility from the Apple® menu bar.
(C) When the Disk Utility window opens, select "Macintosh HD" in the list on the left.
(D) Select the First Aid tab on the right
(E) Select the "Repair Disk" button on the lower right of the screen.
If errors are returned repeat this process 2 or 3 times until they are gone.
If you still get errors then you will need to use a third-party disk utility to repair your Mac OS X boot volume, such as Alsoft® Disk Warrior®

(G) Go to Installer > Quit. In the next menu choose Quit again and the computer will restart in OSX
