Summary: Just a little static discharge ...


  I`ve seen this thing before ...  Monitors usually have some sort of
grounding strap from the outside of the CRT tube.  If this is not
connected, static charge builds up on the CRT tube until it finds some
convenient way to arc to ground.  You hear a large *POP*, the screen
jumps, and your computer crashes.  This happens at varying intervals,
depending on humidity, etc.

  Check for a properly connected ground on the monitor's CRT tube.  Do
this VERY CAREFULLY since high voltage may be present inside the 
monitor, even if it is unplugged (capacitors, static electricity, etc.).
If you don't want to pay for a professional service person to do the 
work, at least let the monitor sit unplugged for a while before you
open it (this allows the charge to "leak" off).
