I don't understand your example. What does the processes tab of Task Manager have to do with your problem?
If you turn off your computer, wait a few seconds, and turn it on, do you see the logon screen with at least one user icon, like this:
Does the error message appear at this point?
Assuming that you see the logon screen, does the error message appear when you click one of the user icons and supply the password (if necessary)?
Or do you get to your Desktop without seeing the error message, but the error message appears when you start ANY application program?
What happened to your computer shortly before this problem started? For example, did you install or uninstall any software? Were you infected by malware? Did you remove malware? Please give details.
