Question

A user's PC has been running slowly. The user says there have been no changes to the PC. Which of the following tools should the technician use to troubleshoot the cause of the speed reduction?

Options

ADxDiag
BWindows Memory Diagnostic
CPerformance tab in Task Manager
DDisk defragmenter

Explanation

The Performance tab in Task Manager provides real-time monitoring of CPU usage, RAM consumption, disk I/O, and network activity. This gives the technician an immediate, comprehensive view of which resource is being over-utilized and causing the slowdown - without requiring any prior knowledge of what changed. DxDiag is used to diagnose DirectX and graphics/sound hardware issues. Windows Memory Diagnostic tests for RAM faults but won't reveal broader performance bottlenecks. Disk Defragmenter addresses fragmented HDDs but is not a diagnostic tool and is not relevant to SSDs. The Performance tab is the correct first-stop diagnostic tool for general slowness.
