Your system crashes at various times, sometimes on startup, sometimes when running a software application, sometime when a certain group of applications is running. You suspect a malfunctioning CPU but none of the common issues seem to be present. You have not configured overclocking. There is no overheating. The CPU is seated correctly and locked into its socket.

What can you do to definitively determine if the CPU is causing the system crashes?

A. Downgrade to a CPU that has fewer cores and is less demanding on your system resources?
B. Throttle the processor to reduce the operating frequency and minimize power consumption
C. Switch to a comparable CPU from a different manufacturer
D. Replace the suspect CPU with a known good CPU of the same make and model
