Finder totally messed up - OSX 10.9.5

You have restarted the computer?

You have tried the computer in Safe Mode? Try safe mode if your Mac doesn't finish starting up (formerly: What is Safe Boot, Safe Mode? (Mac OS X)) - http://support.apple.com/HT201262 - "You can use safe mode to help you resolve issues that might keep your Mac from completely starting up."

Might be a corrupt .plist.

Do a backup, preferably 2 backups on 2 separate drives.

Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library. Then go to Preferences/com.apple.finder.plist. Move the .plist to your desktop.

Re-launch Finder by restarting the computer and test. If it works okay, delete the plist from the desktop.

If the same, return the .plist to where you got it from, overwriting the newer one.

Thanks to leonie for some information contained in this.
