14.3  Bug Check / Blue Screen Event Records 
When the system experiences a bug check (blue screen), multiple records will be written to the event log. The first is a Bug Check / 
Blue Screen OS Stop/Shutdown Event Record; this can be followed by multiple Bug Check / Blue Screen code OEM records that will 
contain the Bug Check / Blue Screen codes. This information can be used to determine what caused the failure.
