Question

what are three important considerations when installing a cpu on a motherboard? (choose three.)
the cpu contacts are first cleaned with isopropyl alcohol.
the cmos eprom battery is removed prior to installing the cpu.
maximum insertion force is applied to the load lever so the cpu is locked in place.
the cpu is correctly aligned and placed in the socket.
the cpu heat sink and fan assembly are correctly installed.
antistatic precautions are taken.

Explanation:

1. The CPU is correctly aligned and placed in the socket: Proper alignment is crucial to ensure the CPU pins fit into the socket without damage.
2. The CPU heat sink and fan assembly are correctly installed: The heat sink and fan are necessary to dissipate heat from the CPU, preventing overheating.
3. Antistatic precautions are taken: Static electricity can damage the CPU, so antistatic measures (like using an antistatic wrist strap) are essential.

Incorrect options:

• Cleaning CPU contacts with isopropyl alcohol is not a standard step during installation (usually done if contacts are dirty beforehand, not a primary installation consideration).
• Removing the CMOS battery is not related to CPU installation.
• Applying maximum force to the load lever can damage the CPU or socket; the lever should be closed with appropriate, not maximum, force.

Answer:

• The CPU is correctly aligned and placed in the socket.
• The CPU heat sink and fan assembly are correctly installed.
• Antistatic precautions are taken.
