Understanding Desktop Architecture and Key Diagnostic Approaches

Desktop computers, with their modular tower designs, offer robust performance but are prone to component-specific failures due to dust accumulation, power surges, and heavy usage common in Niagara's variable climate. At JTG Systems, we start diagnostics with a thorough hardware inspection, using multimeters for voltage checks and stress tests for stability, ensuring we pinpoint issues without unnecessary disassembly.

Common Symptoms and Failure Points in Desktops
