Testing in a new User will quickly tell you if the problem is system wide or if it's your User's folder that contains the problem. You can use the Guest User or create a new test User.
CREATE A NEW USER
Go to System Preferences --> Create a New User in Accounts. Switch to the New User by logging out/in or use Fast User Switching.
You can skip Apple ID setup.
Do you still see the issue?
If yes, then the problem is with your base files.
If no, then the problem is in your User's folder.

Jun 12, 2014 12:39 PMby Eric Root,After tesing in a new account, if the problem is still there, try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don't do them all at once.
