As soon as I type in anything (Outlook express, Internet etc) the computer will shut down automatically. I am only typing now because I log in as another user so I have 2 running, so when it tries to shut down it will prompt me to shut down. I click no and it goes, but I type another word and it comes up again.

Here is my hijackthis log
