My XP Pro machine will reboot spontaneously. I have installed Avast Free edition 5.0.396 and when I am surfing the web it suddenly reboot. I have previously set the setting to not do this. (My Computer>Properties>Advanced). So when it blue screens I can troubleshoot. But regardless of that setting it just restarts. I cannot obtain a dump file because of this.
So what exactly have you set on that page (in System failure group)?
“Automatically restart” is unchecked?
What is selected in the “Write debugging information” combo?
