Is there an underlying theme or premise for PC Fear Factor?
Yes, and it is one I think most people will grasp immediately, even if they have never articulated it themselves. The underlying theme is that computers are unstable equilibriums, and that any change even the most seemingly innocuous one can disrupt the unstable equilibrium. By definition, when an unstable equilibrium is disturbed, disaster follows, because the system does not return to its previous state of equilibrium. Sometimes, you dont even have to make a change to your computing environment to disrupt your unstable equilibrium. Sometimes and I think readers will relate to this the simple act of powering down ones computer and turning it back on precipitates a computer disaster. Something has caused some critical system files to become corrupted, and in doing so has turned your computer into an elegant but expensive paperweight.
