Understanding Common Computer Architectures and Diagnostic Essentials

Modern computers, whether Windows-based PCs or Apple Macs, rely on layered architectures involving processors, memory, storage, and peripherals that can falter under daily stress. Diagnosing issues starts with systematic checks: powering on to assess boot sequences, running hardware scans for thermal or connection faults, and probing software logs for error codes. In Niagara's variable climate, dust buildup and power fluctuations often accelerate wear on components like fans and capacitors.

Typical Symptoms and Failure Modes in PCs and Macs

• Sudden shutdowns signaling overheating from clogged vents or failing fans in desktop towers.
• Erratic cursor movements indicating trackpad or mouse sensor degradation on laptops.
• Distorted audio output from loose jacks or corrupted sound drivers in multimedia setups.
• Intermittent connectivity drops due to outdated Wi-Fi modules or router mismatches.
• Failed startups with BIOS beeps pointing to RAM seating issues or incompatible modules.
• Crackling screens from backlight inverter failures in older LCD panels.
• Swollen batteries leaking electrolytes, common in portable devices left charging overnight.
• Overheating GPUs during gaming sessions, triggered by dust-obstructed heatsinks.
• Corrupted file access from fragmented HDD platters or failing read/write heads.

• SSD write failures from NAND cell exhaustion after heavy use cycles.
• CPU throttling under load from thermal paste drying out over years.
• Motherboard capacitor bulging visible during visual inspections of internals.
• Power supply humming from coil whine in high-wattage units.
• Optical drive ejection problems from belt slippage in CD/DVD trays.
• Touchscreen unresponsiveness on convertibles from digitizer layer delamination.
