Hello, and thank you for asking your question, with JustAnswer.com/Mac.
I am Sr. Mac Tech Support Specialist, TD, glad to assist you.

--------------------------------------------------------------------------------
Here are some steps you can try to resolve the issue:
-PMU RESET-
The Power Manager is an integrated circuit (computer chip) that is usually on the logic board of your Mac computer.

It is responsible for power management of the computer. It controls backlighting, hard disk spin down, sleep and wake, some charging aspects, trackpad control, and some input/output as it relates to the computer sleeping.

• If the computer is on, turn it off.
• Disconnect all the connections going into the Mac except for the Power cord.
• Once all connections have been disconnected, remove the power cord from
the Mac.
• Wait 20 seconds.
• Reconnect the keyboard, mouse and power cord back into the computer.
• Press the Power button to restart the Mac computer.
----------------------------------------------------------------------------------------------------------
If this does not work, try this procedure below:

Thanks for your reply.

I am going to have you take your Mac into Safe Mode to see if we can't remove a possible folder(s) that may be affecting your Mac's start up function.
try these steps:


-SAFE BOOT MODE-
• Reboot your Mac
• Upon restarting your Mac, press the Shift key.
• Hold the Shift key until you see a White Screen with Gray Apple icon and eventually a spinning gear.
• When you see the Spinning gear, release the Shift key.
• Allow the Mac to continue booting up. Also this may take a little while
(NOTE: this may take anywhere from 5 to 15 minutes to load to the Safe mode screen depending on the performance of your Mac, but if it exceeds this time, shutdown your Mac and try just once more. It may have just frozen up the first time around for you.)

• You are going to enter the Safe Mode (which looks like your main desktop enviroment the only difference is certain startup items are disabled.)

• Once within the Desktop in Safe Mode
• From the Finder Menu, click Go> Go to Folder
• Type in this line: /System/Library/StartupItems
• This path, is going to take you to the System Library folder which has all of your Mac OS X Startupitems.
• Remove all of those folders to the Trash.

*Reboot your Mac normally and see if you can access your normal User desktop environment.

  • Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill Bill M. Schenectady, New York
