A technician assembled a new PC. After a few minutes, the computer slows down and then shuts itself off. Which of the following is the most likely cause of the failure?

Question

Options

• AThermal paste was not used.
• BThe GPU needs additional power.

• DThe motherboard is incompatible.

• D
  12% (3)

Explanation

When a newly built PC runs for a few minutes and then slows down and shuts off, this is a hallmark symptom of CPU overheating. Thermal paste is required between the CPU and its heatsink to ensure efficient heat transfer; without it, the CPU rapidly reaches its thermal throttling threshold (causing slowdowns) and then hits its thermal shutdown limit (causing a power-off) to prevent permanent damage. Insufficient GPU power would typically cause crashes or failure to POST, not a delayed thermal shutdown. Insufficient memory causes performance issues and crashes but not thermal-related shutdowns. Motherboard incompatibility would usually prevent the system from booting at all.
