Overheating from direct sunlight can damage which components of a computer?

• A. LCD screen
• B. Hard drive
• C. Processor
• D. LCD screen, hard drive, and processor

Answer: (D)

Direct sunlight raises the computer’s temperature, pushing components beyond their safe operating range. Each part has different sensitivities to heat, and when exposed to high ambient temperatures, all of them can suffer.

The LCD screen relies on precise liquid-crystal behavior and a stable backlight. Excessive heat can cause the liquid crystals to misbehave, leading to color shifts, slower response, or degraded display quality, and can shorten the backlight’s life.

The hard drive, especially a traditional spinning-disk model, has moving parts that are very sensitive to temperature. Heat causes expansion, can degrade lubricants, and increases the risk of mechanical wear or data errors as tolerances tighten with temperature.

The processor contains microscopic transistors that operate within a narrow temperature range. When it overheats, the system will throttle performance to cool down, and prolonged high temperatures can reduce the chip’s lifespan and reliability.

Because overheating from direct sunlight can affect all three components, the best choice is that LCD screen, hard drive, and processor can all be damaged.
