    First I would remove every startup entry in the system preferences user logon panel, (write down which apps you have removed so you can layer replace the ones you want or to troubleshoot) then in Library/launch daemons and launch agents folder (temp copy these things out of those folders). Then in disk utility, repair permissions, then, Force shut down and restart a couple times and see if it helps.

    If all that doesn't help, you should also google how to repair disk from booting in to recovery mode. After all that maybe a repair, but they will want you to reinstall possibly first.

    I would also do this:

    To clear your kext cache open terminal and enter the following:

    • sudo chown root:admin /
    • enter your password
    • sudo kextcache -system-prelinked-kernel
    • sudo kextcache -system-caches
    • Open System Preferences
    • Open Startup Disk
    • Ensure Startup Disk is still set correctly
    • Reboot

    You may not see an improvement on the first shutdown/startup after you have completed the above method but after that you should do.
