All of that doesn't really touch anything inside your Home folder.
I'd suggest starting in Safe Mode and see if the problem still occurs, but because of the length of time it takes to begin happening, that's probably not a viable alternative.
Instead, go to System Preferences > Users & Groups > Login items and delete all login items (-), you can always add them back with the (+). Also look in /Library/Startup Items. Nothing is put in that folder by default, so anything in there is yours.
Test and see if the issue reoccurs.
Another thing it could be is permissions or ACLs within your Home folder. Boot up holding command-r keys into your Recovery Volume.
From the menu bar choose Utilities then select Terminal.
At the prompt type resetpassword
The Password reset utility will launch (do not reset password)
Instead, click your Mac hard drive.
Then from the drop-down select the user account you want to repair. At the bottom of the window, you’ll see an area labeled ‘Reset Home Directory Permissions and ACLs’. Click the Reset button there.
The process takes a couple of minutes. When it’s done, quit the programs you’ve opened and restart your Mac.
I wrote a little diagnostic program to help show what might be causing these problems. Download EtreCheck from http://www.etresoft.com/download/EtreCheck.zip, run it, and paste the results here.

Sorry for the delay -- what a two week period. I ran the test (Apple will not allow me to paste results -- don't know why). I have done the following:
1. Checked all preferences to see if they are corrupt.
2. Cleared all caches.
3. Zapped the PRAM
4. Bought a new Mac Pro (mine was four years old)
5. Created new account (administrator).
some improvements. Yet, here is what is still going on. First, when the log-in screen pops up, the mouse pointer is in the upper left area of the screen where it is frozen for about 10 minutes. Then, I can log in. BTW, I have tested to see what programs are in memory. Then I next find that the notification button (upper right) and the dock does not work for about 3 minutes. Finally, occasionally, the system will not shut down properly. The only thing that is left to be done is to carbon copy the HD to a new HD in the off-chance that I have a problem with the HD.
I am stumped by what is going on.
Any help greatly appreciated.
