I think you have a corrupted System Preferences .plist file

You can remove the current .plist file in ~/library/preferences/ drag that .plist to the desktop (as a backup) and try System Preferences again. It will automatically create a new, working .plist file.

uhm.... and if i don't have this file?? I searched entire disk, but nothing. – elpsk Mar 28 '12 at 8:19
Try it in here ~/Library/Preferences/SystemConfiguration/preferences.plist – revolver Mar 28 '12 at 8:32
Nothing appened. Also restarted system. – elpsk Mar 28 '12 at 9:24

Solution from here. Or you can use Michiel's. They are similar,except that the method below doesn't back up your plist.

  1. Quit the System Preferences application, if it is running.

  2. Launch the Terminal application (found in /Applications/Utilities/).

  3. Type sudo -s and press Return

  4. Enter the password for the current user profile (NOT the root password).

  5. Type cd /Library/Preferences/SystemConfiguration and press Return (note case sensitivity).

  6. Type mv preferences.plist preferences.plist.old and press Return.
