i have 2 problems

[george roman <georgeromanadrian@yahoo.com>]

- i can't make anny users (i can create them, but i
can't grant access whith users other than root) they
exist in    
/etc/passwd and in /home  (in /home their directory is
empty) i can use the command "su username" but i can't
login with their name.  
 


- when i want to turn off my computer i usally use the
comand "poweroff". most of the times it works but
sometimes my sistem crashes(the screen turns black and
i can't use my keyboard to enter in text mode with
C-A-F1 for example) 
i've tried with "shutdown -h now"  and it is the same
problem

10x for your time.
