I have a P III Laptop and Win XP is installed on that.

I am facing a problem of automatic shutdown. Whenever, I log on to internet a system error message pops up that 'The system will restart after 60 seconds'. I performed a full scan of hard drive with the help of Norton and nothing was found. There is something written 'Nt Authority\System' on the error message. It happens again and again whenever I connects to internet. By the way, I am using dialup connection.

Is the above problem clear or should I type the whole error messag, if you guys are percieving problems understanding it. Any help or information in this regard will be highly appreciated...
