Boot Logging is a feature in Windows that records the drivers that are loaded during the boot process. By enabling Boot Logging, the NTBTLOG.TXT file is created, which contains a detailed log of all the drivers that were loaded successfully or failed to load during startup. Therefore, this file can be used to troubleshoot issues related to device drivers not loading properly.

      Computer case

    • C.

      Heatsink / cooling fan

    • D.

      Power supply

    • E.

      Motherboard

    Correct Answer
    C. Heatsink / cooling fan
    Explanation
    The heatsink/cooling fan will most likely need to be upgraded in order to support a CPU from a different manufacturer because different CPUs may have different thermal requirements and therefore require different cooling solutions. The motherboard may also need to be upgraded as different CPUs may have different socket types and may not be compatible with the current motherboard. The surge protector, computer case, and power supply are not directly related to the compatibility of the CPU from a different manufacturer.
