技術者が、ランダムな BSOD アラートが発生し、通常の使用中に断続的にフリーズするコンピューターのトラブルシューティングを行っています。日が経つにつれてパフォーマンスが低下します。新しいソフトウェアやハードウェアの変更は実装されていません。フリーズは、パフォーマンスを集中的に使用する操作中に発生します。次のハードウェア コンポーネントのうち、最も問題となる可能性が高いのはどれですか。
正解:C
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.
