MacOS how to find what all options are present in the OS?

After cleaning utility CleanMyMac and restarted the laptop lost the Dock and the Wallpaper, constantly flashing (what appears then black screen)

Monitoringu see what works crash Report and it seems that something was in the startup and went away. How can you determine what the problem is and solve it ?
PS In the settings of the startup nothing, but the situation has not changed
In the console always appears the following failed to start process notification for pid #### (16)
#### - always different

Restore from the backup system. You can search the action log cleanmymac.
