Now you're just pretending I'm stupid...
I asked you to tell me what it does, not how to do it. I know how to press ctrl+alt+del
So, basically, what I'm asking is what does the process csrss.exe do, and why should I end it? I can't see how it would help to stop a process when the main problem happens just after I type in the password.
Same thing goes for the second suggestion you had.
And as I said, I really don't think this is a software problem.
