Hello and thanks for using

What OS are you running? ie. 10.4.11 or 10.5.6

Try starting your computer using safe boot. This performs some system maintenance.

To perform a safe boot do the following:

• Be sure the computer is shut down.
• Press the power button.
• Immediately after you hear the startup tone, press and hold the Shift key.
• Tip: The Shift key should be held as soon as possible after the startup tone but not before.
• Release the Shift key when you see the gray Apple and progress indicator (looks like a spinning gear).

Restart the computer

Will it let you open disk utility? If not what error message do you get?
Customer: replied 6 years ago.
It will not. No error message. Icon just ghosts up toward me like it's opening, but nothing happens. When I try to open certain apps on the bar they just bounce, but never get the black triangle/arrow next to them.

This will bring up your home folder. Go into a folder called Library and then another folder called Preferences. Delete the file called

Customer: replied 6 years ago.
Tried to install. Mac wouldn't open the dmg document...
OK we will install that later. You will need to check the disk and do an archive and install. You will need the 10.4.11 disks, Do you have these?
Customer: replied 6 years ago.
I do. Can you list instructions? Then I'll complete and return to you.
Check the disk using Disk Utility first. If it finds errors restart after fixing them and test your applications

Insert your Mac OS X Startup disk
•Reboot your Mac
•At the Apple Chime, press the C key and hold it until you see a White screen, gray Apple and eventually a Spinning gear.
• Release the C key only after you see the Spinning gear.
•Mac will boot from the startup disk to the Installer environment.
-If you are prompted to select a language and you do not see the menu bar at the top of the screen, click the right arrow button to proceed to the next screen.

• At the very Top From the Installer Menu bar, click Utilities > Disk Utility and open up Disk Utility application.
• Click on on the hard drive at the top of the window in the left sidebar and
• Select "Repair Disk"
**Let Disk Utility run this repair the disk until completion
• At the end of this process, reboot your Mac The next step would be to do an archive and install.
You will need the system disk (disk that came with the computer) or Leopard/Tiger install Disk to do the following.

If Disk Utility doesn't prove successful the next step would be to reinstall 10.4

This will reinstall your operating system but leave your files and programs intact.
Very important is to choose the archive and install option and to Preserve Users and Network Settings.

Here is directions for the Archive and Install process.

Customer: replied 6 years ago.
Sorry it's taken so long. Major problems. I followed the above directions to the letter. After performing the Archive and Install (with Preserve Users and Network Settings selected) I was asked for my login information and the info that worked prior to the arc/inst. did not work. After trying all combinations of user/password XXXXX was forced to reinstall 10.4 from the start. I lost a good bit of information. I backed up my documents folder, but lost all of our photos and itunes library.
Is there anything that can be done to find photos or itunes library?
On a happy note, though. Applications are opening!!! Problem is solved, but I aparently didn't have the proper back-ups made...any thoughts?
Click the Apple icon in the top left and choose system preferences.

Click on Accounts.

Is there just 1 account listed here or is your old account here as well?

If it is just 1 account. You will need software and an external hard drive to restore your deleted photos and itunes library.

The following software is very good at this.
