Random restarts while connected to the internet

[maineiac]

A friend of mine asked for my help with her computer, it's randomly restarting while connected to the internet. I don't think it's overheating or a battery issue because it's fine when offline. It's a Toshiba Satellite laptop, latest updates and virus definitions, Adaware found some spyware that has now been removed. I'm out of ideas, any help?

To help diagnose the problem, it may be helpful to turn of “Automatic restart after system failure”. To do so, open the properties menu of My Computer and navigate to the Advanced tab. Click on the Settings button under Startup and Recovery and uncheck “Automatically Restart” under the System Failure heading.

Report back with any error messages produced when the computer hangs.
