A technician needs to install additional RAM in a laptop that only has one SODIMM slot occupied. The existing module is DDR4-3200 8GB. Which action should the technician take to maximize compatibility?
Answer: Install an identical DDR4-3200 8GB module in the second slot
Installing an identical module ensures dual-channel operation and full compatibility without risking speed mismatches.
Which connector type is used to provide supplemental power to high-end PCIe graphics cards?
Answer: PCIe 6-pin or 8-pin connector
High-end GPUs require supplemental power via dedicated PCIe 6-pin or 8-pin connectors from the power supply.
A user reports their PC powers on but displays nothing on the monitor. The GPU fan spins. What should the technician check first?
Answer: Reseat the GPU in the PCIe slot
Reseating the GPU resolves loose connection issues that cause no display output despite the card receiving power.
What is the primary purpose of thermal paste applied between a CPU and its heatsink?
Answer: Fill microscopic air gaps to improve thermal conductivity
Thermal paste fills microscopic surface imperfections between the CPU and heatsink to maximize heat transfer efficiency.
A technician is replacing a failed 2.5-inch SATA SSD in a desktop. The motherboard only has M.2 slots available. What is the best solution?
Answer: Install an M.2 SATA SSD in one of the M.2 slots
M.2 SATA SSDs use the M.2 form factor but communicate over the SATA protocol, which is supported by M.2 slots with SATA keying.
Which tool should a technician use to safely discharge static electricity before handling internal PC components?
Answer: Antistatic wrist strap connected to chassis ground
An antistatic wrist strap continuously drains static charge from the technician's body to ground, preventing ESD damage.
A desktop PC fails to boot and emits a series of beep codes. What does the beep code system indicate?
Answer: POST hardware diagnostic codes indicating a specific failure
Beep codes are POST (Power-On Self-Test) audio diagnostics that signal specific hardware failures before video output is available.
