Startup and Shutdown

[Shane]

Whenever I goto shutdown, hibernate or restart my
computer, it goes to the blue windows xp screen and then
just stays there forever...I end up having to shut it down
by holding in the power button. It was working fine not
too long ago but suddenly went 'dodgy'.Any ideas?

Also, when I goto startup, I want the user screen to come
up, but I don't want to have to enter my password. Is
there a way to do this?

One last thing, when I goto use Task Manager, I get a
message saying:
"Task Manager has been disabled by your system
administrator"

Thanks. I'll try re-installing first though because it
was working fine before. Is there something I could of
done for this to happen?
