A technician has recently installed some new memory in a PC. When the computer is rebooted, the technician hears loud noise coming from inside the case. Which of the following is MOST likely the cause?

Question

Accepted Answer

B. Something is obstructing one of the fans When installing memory, cables near the DIMM slots can be inadvertently displaced and come into contact with a spinning fan blade, producing a loud rattling or grinding noise. This is the most common physical cause of sudden noise after internal component installation and should be investigated by visually inspecting all fans with the side panel open.

Answer

A. The CPU is incompatible with the memory CPU and memory incompatibility causes the system to fail to POST or emit BIOS beep codes, not a loud mechanical noise.

Answer

C. One of the hard drives is failing Hard drive failure typically produces a clicking or grinding sound from the drive itself and would be unrelated to a memory installation.

Answer

D. The new memory is over heating Overheating memory modules do not produce audible noise; heat-related memory failure manifests as system instability or crashes.
