CPU INSTALLATION FACTS EXAM QUESTIONS WITH 100% RATED ANSWERS, GET A+
Should you use force to insert the CPU? - No, applying pressure can bend or break pins and render the CPU useless. How do you secure the CPU after placing it in the socket? - Relatch the socket cover; with a ZIF socket, use the lever to lock it into place. Why might you need thermal paste during CPU installation? - Thermal paste fills imperfections between the CPU and cooler, enhancing heat transfer. What should you do if thermal paste is needed? - Apply a thin, even layer on the CPU...
