A device for use in inspecting a CPU and a method thereof are provided. The device comprises a receiving interface and a processor. The receiving interface receives a first data stream from the CPU when the CPU executes a reference hardware inspection program in a first time interval, and receives a second data stream from the CPU when the CPU executes the reference hardware inspection program in a second time interval. The processor sets the first data stream as a good log, and sets the second data stream as an erroneous log. The processor compares the good log and the erroneous log to determine a segment of the erroneous log as an erroneous range, and determine a defect of the CPU according to the erroneous range.
