A technician replaces a CPU and then notices the fans are continuously running. The computer randomly crashes after about five minutes. Which of the following should the technician do to prevent this

The correct answer is A. Apply thermal paste.. The continuous fan operation and random crashes after a CPU replacement strongly suggest overheating, which indicates a failure to apply thermal paste between the CPU and its heatsink.

Why each option

The continuous fan operation and random crashes after a CPU replacement strongly suggest overheating, which indicates a failure to apply thermal paste between the CPU and its heatsink.

AApply thermal paste.Correct

After replacing a CPU, applying thermal paste (or ensuring it's properly applied if pre-applied on the heatsink) is crucial to facilitate efficient heat transfer from the CPU to the heatsink. Without proper thermal paste, the CPU will quickly overheat, triggering continuous fan operation (as the system tries to cool it) and eventually leading to system crashes or shutdowns due to thermal throttling and protection mechanisms.

BUse Trusted Platform Module.

Trusted Platform Module (TPM) is a security component that provides cryptographic functions and is unrelated to CPU cooling or system stability issues like crashes from overheating.

CReplace the socket.

Replacing the CPU socket is a drastic measure and highly unlikely to be the cause of overheating symptoms following a CPU replacement; improper thermal paste application is a far more common oversight.

DImplement secure boot.

Implementing secure boot is a UEFI firmware security feature that helps prevent malicious software from loading during startup and has no bearing on CPU temperature management.
