PC MAINTENANCE — Diagnosing gradual slowdowns Your computer has gradually become slower over weeks or months. Which is the most likely cause among the following options?

Introduction / Context:Performance troubleshooting starts with recognizing patterns. A gradual slowdown often indicates a software-related issue rather than catastrophic hardware failure. Understanding common causes enables quick, practical fixes.

Given Data / Assumptions:

• Slowdown is progressive, not a sudden crash.
• No mention of high temperatures, sudden shutdowns, or error beeps.
• Consumer Windows PCs are typical targets for adware and unwanted background processes.

Concept / Approach:Adware/spyware and other potentially unwanted programs accumulate over time, adding startup entries, browser extensions, telemetry, and background services. These consume CPU cycles, RAM, and disk I/O, leading to sluggish performance. While overheating can cause throttling, it more often produces spikes, shutdowns, or performance drops under load rather than week-by-week degradation.

Step-by-Step Solution:Match symptom pattern (gradual slowdown) to likely cause (software bloat/malware).Consider alternatives: aging hardware does not “get slower” purely with time; performance changes stem from software or failing components.Select the most plausible option → adware/spyware infection.

Verification / Alternative check:Task Manager or Activity Monitor often shows high background CPU/RAM usage; anti-malware scans detect PUPs; disabling startup entries and cleaning browsers restores speed, confirming the diagnosis.

Why Other Options Are Wrong:Overheating — can throttle, but usually correlates with load spikes or clogged fans; still possible but less typically “gradual” in isolation.Processor getting old — silicon age alone does not slowly reduce speed; software and OS changes do.Dropped sandwich — humorous distractor; not a standard cause.“Perfect” wall voltage — irrelevant to slow performance.

Common Pitfalls:Ignoring browser extensions and startup apps; neglecting disk health (HDDs fragment or fail). Combine malware scans with disk checks and OS updates for a thorough remedy.

Final Answer:Adware/spyware is infecting your PC
