Don't know what you mean by 20 formats.
Try setting your user account so that you need to input your password when logging in. Restart and hold down the shift key- this will restart you in Safe Mode- no 3rd party apps will be loaded. After adding your password at the login, hold the shift key again while the login process completes. See if this stablizes your system.
If not, create a new user with admin privilieges and login to that account- if that cures it, then modes have been made to your own ~/Library and something is amiss. TRhis can be corrected.
