Understanding Computer System Architecture and Diagnostic Essentials

Modern computers blend intricate hardware layers with sophisticated software ecosystems, making precise diagnostics crucial for Niagara users facing slowdowns or crashes. Our technicians at JTG Systems employ advanced tools to dissect these systems, revealing hidden faults without upfront costs.

Key Components in Computer Architecture

• Central Processing Unit (CPU): The brain executing commands; overheating often signals diagnostic needs.
• Motherboard: Connects all parts; corrosion from dust buildup requires visual and electrical checks.
• Random Access Memory (RAM): Temporary data storage; insufficient capacity leads to lag, tested via stress software.
• Storage Drives: Hard Disk Drives (HDDs) or Solid State Drives (SSDs); failing sectors cause boot failures, scanned with sector mapping tools.
• Graphics Processing Unit (GPU): Handles visuals; artifacting on screens points to driver or hardware conflicts.
• Power Supply Unit (PSU): Delivers stable voltage; flickering indicates insufficient wattage, measured with multimeters.
• Input/Output Interfaces: Keyboards, mice, ports; intermittent connectivity demands signal integrity tests.
• Cooling Systems: Fans and heatsinks; excessive noise reveals thermal throttling risks.
• Network Adapters: Wi-Fi or Ethernet; dropouts necessitate firmware updates and bandwidth diagnostics.
• Bios Firmware: Low-level control; outdated versions trigger compatibility issues, updated post-hardware verification.

Common Symptoms Prompting Free Diagnostics

• Sudden shutdowns during tasks, hinting at PSU instability.
• Blue screen errors, often tied to RAM or driver mismatches.
• Slow boot times, signaling HDD fragmentation or malware.

• Viral infections, detected via antivirus scans during intake.
• Hard drive clicks, early warnings of mechanical failure.
• Keyboard stickiness, from spills in Welland coffee shops.
• Monitor flickers, linked to inverter problems in desktops.
• BIOS beeps, codes interpreted for memory slot faults.
• Expansion card errors, tested in PCIe slots.
• Optical drive skips, obsolete but still diagnostic targets.
• CMOS battery depletion, causing date/time resets.
• Thermal paste drying, accelerating CPU wear.
• Fan bearing wear, leading to imbalance vibrations.
• Capacitor bulging on boards, visual cues for replacement.
• SATA cable degradation, causing data transfer halts.
