cmd.exe, conhost.exe & csrss.exe using 20% of CPU after boot

[L 4 Life]

I am running a Windows 7 Pro on my laptop and I have noticed something wrong on this laptop. Whenever I am booting my laptop then it was running bit slow then the normal speed. So I just took a look at the Task Manager where I saw that the cmd.exe, conhost.exe & csrss.exe were using more then a 20% of CPU which seems to be the reason for slowing down my machine. So I ended the cmd.exe which resulted in killing both the other processes as well. What is the problem with this processes?
