Repair Disk and Permissions
Repair Disk: You should do this once a month or so as regular maintenance.
Also before any major system upgrade (Jaguar to Panther to Tiger). These steps will check for, and usually repair, any corruption on your OS X boot volume
(A) Boot from your Mac OS X Install Disc 1 CD. Put CD 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 untill 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®

(F) After Repair Disk completes go to Disk Utility > Quit. Focus returns to Installer.
(G) Go to Installer > Quit. In the next menu choose Quit again and the computer will restart in OSX
As part of your regular (monthly) maintenance you can repair the disk without the install disk by starting up in Safe Mode ...
Start up in Safe Mode .. this will run the "Repair Disk" utility.
Be sure the computer is turned off.
Now press the power button.
Just after you hear the startup tone (NOT BEFORE), press and hold down
the shift key.
Now release the shift key when you see the start up screen with the gray
background with the Apple logo and the progress indicator.
During the startup, you will see "Safe Boot" on the Mac OS X startup screen.
To leave the Mac OS X Safe Mode just restart your Mac normally, without
holding any keys during the startup period.
Next:
Repair permissions: Before and After any System Update. Close all files and applications on the disk you want to repair. Go to Macintosh HD/Applications/Utilities/Disk Utility and double click it. Then select "Macintosh HD" in the left panel and First Aid at the top. Then click on "Repair Permissions."
If your problem is still not solved ..
Go to Macintosh HD/Users/Your_Name/Library/Preferences and trash the files:
- com.apple.ATS.plist
- com.apple.BezelServices.plist
Restart. If this did not help, go to Users/Your_Name/Library and drag the folder Preferences to the desktop. Restart and see if this solved the problem
