why desktop apps are able to kill my freebsd box?

[Timo]

Who decided to run any privileged application, in terms of doing what 
you didn't want it to? Did you at all try to implement anything you were 
not sure of? Or what did you ask again?

What do you want to employ in the first place, and what security risks 
are negotiable? (firefox/freezings? try to reseat every piece of 
hardware until no freeze is found, including cpu, then complain about 
software)
