NEW QUESTION # 121
A technician is troubleshooting a computer that has random BSOD alerts and intermittently freezes during normal use. Performance degrades as the day goes on. No new software or hardware changes have been implemented. Freezing occurs under performance-intensive operations. Which of the following hardware components is most likely at fault?
- A. RAM module
- B. HDD
- C. TPM
- D. Video card
Answer: A
Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
Random BSODs (Blue Screen of Death), intermittent freezing, and degraded performance under load are common symptoms of failing or faulty RAM (Random Access Memory). Here's the reasoning:
RAM Module (Correct Answer):
Faulty or failing RAM can cause random BSODs due to memory errors when the system attempts to read or write to corrupted memory locations.
Intermittent freezing, especially under performance-intensive operations, can occur because the CPU relies heavily on RAM for active processing tasks.
Over time, heat generated during usage can exacerbate RAM instability, leading to progressively worse performance throughout the day.
Solution: The technician should run a memory diagnostic tool, such as Windows Memory Diagnostic or MemTest86, to confirm if the RAM is at fault.
Incorrect Options:
A: Video Card: A faulty video card can cause graphical glitches, screen artifacts, or crashes, but it is unlikely to cause system-wide performance degradation and random freezing under normal operations unless the issue is specific to GPU-intensive tasks (e.g., gaming or video rendering).
B: HDD: A failing hard drive can cause system slowdowns and freezing, but it typically produces other symptoms such as read/write errors, boot failures, or clicking sounds. HDD issues do not usually cause BSODs unless critical system files are corrupted.
D: TPM (Trusted Platform Module): A TPM is a hardware-based security module used for encryption and secure authentication. It does not affect performance or cause BSODs or freezing under normal operation.
Key Takeaway:
The symptoms described (random BSODs, intermittent freezing, and degraded performance under load) are most likely caused by faulty or failing RAM. Memory diagnostic tools should be used to confirm the issue.
