( D ) Incorrect wallpaper settings
Answer: A
Explanation:
Unexpected shutdowns due to overheating are most commonly caused by problems with the cooling system. The cooling system of a laptop or desktop includes components such as fans, heat sinks, and thermal paste, all of which work together to dissipate heat generated by the CPU and GPU. If a fan is malfunctioning, blocked by dust, or operating at reduced efficiency, it cannot adequately cool the system. Similarly, a heat sink that is improperly seated or coated with old thermal paste will fail to transfer heat effectively from the processor to the surrounding environment. Over time, thermal paste can dry out or degrade, further reducing heat transfer efficiency and increasing the likelihood of the system reaching critical temperatures. When the system detects that temperatures are dangerously high, it will often initiate an automatic shutdown to protect hardware components from permanent damage.
Technicians addressing unexpected shutdowns should inspect the cooling hardware thoroughly. Cleaning accumulated dust from fans and vents can restore airflow and improve cooling efficiency. If necessary, replacing a malfunctioning fan or reapplying thermal paste can significantly lower internal temperatures and prevent future overheating. These steps are essential for maintaining system stability and preventing damage to critical components such as the CPU, GPU, and motherboard.
Incorrect screen resolution does not cause overheating or unexpected shutdowns. While higher resolutions may demand slightly more processing power from the GPU, they do not generate heat to the extent that a faulty cooling system would. Similarly, a weak Wi-Fi signal is unrelated to system temperature and cannot trigger thermal shutdowns. Wallpaper settings, regardless of file size or resolution, also have no impact on the cooling performance of the system.
