Shut Down Woes

When I click shutdown on my Win 98 SE, everything shuts down, my monitor goes black and standby light shows, then immediatly everything restarts. It was running scandisk each time, saying Windows was not shutdown properly, but I turned that off.
I have tried every tip, from Microsoft, but nothing has changed. I used Control/Alt/Del to shut down everything except Explorer and Systray before Shutdown, but made no difference. Any suggestions? I attach myHijackthis scan.
