Power Supply Unit (PSU)

Correct Answer: Inadequate PSU wattage.

The most likely cause of the computer randomly shutting down and the PSU being hot to touch is an inadequate PSU wattage. If the power supply unit cannot provide enough power for all the components, it will overheat trying to supply the needed power, leading to thermal shutdown of the computer to prevent damage. A faulty motherboard, corrupted operating system, or incompatible GPU would not typically cause the PSU itself to overheat.

Correct Answer: Inspect the PSU for any signs of damage, debris, or clogged ventilation

A buzzing noise coming from the PSU is more likely to be caused by a faulty component inside the power supply itself, such as a failing capacitor or a problem with the transformer. A loose connection or power cable would not typically cause a buzzing sound, it could lead to more severe issues like melting the connection or causing power overloading. The best course of action would be to inspect the PSU for any signs of damage, debris, or clogged ventilation. Here's why: 1. Overheating: A clogged ventilation system or a faulty fan can cause the PSU to overheat, which may lead to component failure and produce a buzzing noise. 2. Debris: Dust and debris can accumulate inside the PSU over time, potentially causing short circuits or overheating, which may result in a buzzing noise. 3. Faulty components: If the PSU is free of debris and has proper ventilation, the buzzing noise may indicate a failing component inside the PSU, such as a capacitor or transformer. 4. Safety precaution: Inspecting the PSU for any signs of damage or debris is crucial to ensure the safety and stability of the system. If, upon inspection, the PSU appears to be clean and free of debris, and the ventilation is not obstructed, then the buzzing noise is likely caused by a faulty component. In this case, replacing the PSU would be the most appropriate course of action to ensure the system's stability and prevent potential damage to other components.

Correct Answer: Upgrade the PSU to a higher wattage.

The PSU might not be providing enough power for the entire system, especially during intense workloads. Upgrading to a higher wattage PSU would ensure that there's enough power for all components, including the GPU.
