Explanation

Clicking or grinding noises from inside a PC are a classic symptom of a failing mechanical (magnetic) hard drive. This is commonly called the 'click of death' - it occurs when the read/write heads fail to find their home position and repeatedly reset, producing an audible click. It indicates imminent drive failure. SSDs (C) have no moving parts and cannot produce clicking sounds. Low voltage from a PSU (A) would cause instability or shutdowns, not clicking. Overheated RAM (D) does not produce mechanical sounds.
