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?
A is the correct answer
The most likely cause of the failure is A. Thermal paste was not used.
Thermal paste, also known as thermal grease or thermal compound, is a substance that is applied between the CPU and the heat sink to improve the heat transfer and cooling of the CPU. Thermal paste fills the gaps and irregularities between the CPU and the heat sink, creating a better contact and reducing the thermal resistance .
According to some web search results , some signs and symptoms of not using thermal paste or using it incorrectly are:
•The CPU overheats and slows down or shuts down to prevent damage
•The CPU fan spins faster and louder to try to cool down the CPU
•The PC performance drops or becomes unstable
•The PC crashes or displays errors or blue screens
To fix this issue, the technician should apply thermal paste properly between the CPU and the heat sink, following these steps :
•Turn off the PC and unplug it from the power source
•Open the PC case and locate the CPU fan and heat sink
•Remove the CPU fan and heat sink from the motherboard
•Clean the surfaces of the CPU and heat sink with a lint-free cloth and alcohol
•Apply a small amount of thermal paste (about the size of a grain of rice) in the center of the CPU
•Reattach the heat sink and CPU fan to the motherboard, making sure they are aligned and secured
•Close the PC case and plug it back to the power source
Given the symptoms described, where the computer slows down and then shuts itself off after a few minutes, the most likely cause of the failure is:
A. Thermal paste was not used.
The symptoms indicate a potential issue with overheating, which can occur if the CPU does not have proper thermal contact with the heatsink. Thermal paste helps improve the thermal conductivity between the CPU and the heatsink, allowing heat to dissipate more efficiently. Without thermal paste, the CPU can quickly overheat, causing the computer to slow down or shut off to prevent damage.
