I am unable to access my administrator account. I am running snow leopard on an imac. Have run disk repair, repair permissions and cleared pram several times. I did have some corrupted stuff in extents and some catalog issues but disk repair fixed. When logging into the admin acct. The tool bar on the desk top appears and then a blue screen appears and then the menu with various accounts reappears. The account desktop never appears. I wonder if there would be a corrupt file in the library that should be taken to trash? Seems like there is a fairly straight forward way of restoring the account desktop but i can't remember the process. Any help will be appreciated.
