While assembling a PC, why is thermal interface material applied between the CPU heat spreader and the cooler base?
Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
• The apparently smooth surfaces of the processor and cooler contain microscopic imperfections and air gaps.
• Thermal interface material fills these small gaps and improves transfer of heat from the CPU to the cooling assembly.
• Its purpose is thermal conduction, not electrical insulation, mechanical attachment or automatic overclocking.

Select an option first. || ముందుగా ఒక సమాధానాన్ని ఎంచుకోండి.
Explanation:
• A memory-status indication combined with failure to POST points first toward the memory subsystem.
• Reseating the DIMM verifies that it is fully inserted, while slot and compatibility checks help rule out installation or specification problems.
• Formatting storage or modifying Windows settings is inappropriate because the system has not yet completed the pre-boot hardware stage.
