FWIW: In the ECS mobo machine that I had the static problem with...
the case was properly grounded. By touching the case a static discharge took
place...
which in turn caused an EMI signal which triggered the machine to reboot.

By discharging myself prior to touching the machine...the problem was
'solved'.
