SYMPTOMS

CAUSE

This problem occurs because machine check exceptions are delivered to multiple processors on the computer at the same time. When this problem occurs, the KeBugCheckEx() function may be running on a secondary processor while another processor is performing a task, such as a memory dump. The result is a triple fault exception that forces an automatic reset of the computer.
