How I Diagnose PCs the Unconventional Way

“Smart people solve problems. Geniuses avoid them.”
That’s not just a quote I live by—it’s the foundation of how I approach diagnostics.


🔍 The Conventional Way (and Why I Don’t Rely on It)

Most technicians run a few standard tools:

• Task Manager for performance
• SFC or DISM for system files
• Antivirus scans
• Maybe a third-party suite like CCleaner or Speccy

These are fine for surface-level issues. But they don’t tell you why the system is behaving poorly. They treat symptoms—not causes.


🧠 My Approach: Pattern Recognition + System Behavior

I don’t just look at what’s broken. I look at how the system behaves under stress, over time, and in context.

🔹 I analyze:

• CPU load patterns: not just spikes, but idle behavior and thermal throttling
• RAM usage trends: memory leaks, caching inefficiencies, and swap file abuse
• Disk I/O latency: not just read/write speed, but how the OS interacts with storage
• Network stack behavior: DNS resolution time, packet loss, and Winsock anomalies

🔹 I use:

• Custom scripts to flush, reset, and benchmark subsystems
• Manual inspection of event logs and reliability history
• My own scoring system to rate system health from 0 to 100


🧪 I Don’t Just Diagnose—I Simulate

I often simulate real-world stress:

• Launching multiple apps with different memory profiles
• Running background services to mimic startup load
• Testing network behavior under VPN or proxy conditions

This helps me catch issues that don’t show up in idle mode.


🦾 Tools I Trust (and Sometimes Build)

I use tools like:

Sysinternals Suite for deep system inspection
HWiNFO for hardware-level data
CrystalDiskInfo for SMART diagnostics
• And I’m learning Rust to build my own diagnostic utilities that go beyond what’s available


🧠 MentalistOps Philosophy

“I don’t fix what’s broken. I understand why it broke—and make sure it doesn’t happen again.”

I don’t rely on automation alone. I combine intuition, experience, and technical depth to create a diagnostic process that’s tailored to each machine.


👋 Final Thoughts

If you’re a technician, developer, or just someone who wants to understand their system better—start thinking beyond the obvious.
Look for patterns, not just problems.
Build your own tools.
Challenge the defaults.

Because the real fix isn’t in the patch—it’s in the perspective.
