Hardware Component Replacement

Correct Answer: Check the motherboard's documentation to determine compatible memory types and speeds.

Checking the motherboard's documentation for compatible memory types and speeds ensures that the new RAM will work properly with the system. Incorrect RAM types or speeds can cause errors, crashes, or not function at all.

Correct Answer: Install an SSD to replace the existing HDD.

Installing an SSD (Solid State Drive) to replace the existing HDD (Hard Disk Drive) is the best solution to improve performance when handling large files. SSDs have much faster read and write speeds compared to traditional HDDs, which rely on spinning disks and moving read/write heads. With an SSD, the computer can access and transfer large files significantly faster, reducing wait times and improving overall system responsiveness. Replacing the CPU fan, adding USB 3.0 ports, or upgrading the power supply would not directly address the performance bottleneck caused by the slower HDD when dealing with large files.

Correct Answer: Check for loose connections or replace the inverter if necessary.

The inverter provides power to the laptop's screen. A faulty or loose connection to the inverter can cause flickering and dimming. Checking the connections and replacing the inverter, if necessary, should resolve the issue.
