Hi again, first lets try a
PRAM reset, if that does not solve the issue then please post back after checking a few things listed below.
Make sure you are logged under your name, from the Dock go to System Preferences and select Accounts. Select your users icon in the left hand column, now select Security an make sure “Allow user to administer this computer” is checked. Quit System Preferences.
Now go to the Finder and under Finder, scroll down to Preferences and make sure the first three boxes are checked under Show these idem on the Desktop.
Now from the main menu under Go scroll down to your Users (Home) folder, then Control click on you Desktop icon and scroll down to Get Info. This should open a Desktop Info window. In the lower part of that Desktop Info window make sure under Details you are listed as the Owner, if not unlock the box and scroll to you name. Relock the box and close the Desktop Info window.
