Matrix

A computer shop's real work starts before the counter: understanding what hardware sits in your machine, what's actually compatible, how upgrades interact with load-shedding realities, and whether a repair makes sense versus replacement. In Johannesburg's high-density business environment, that means knowing whether you need faster processors for heavy rendering, solid diagnostic tools to trace intermittent faults, or proper cable management and thermal solutions for systems running in server rooms or hot offices. Experience shows in the details—recognising early SSD failure, understanding memory compatibility across generations, knowing which power supplies handle inverter output safely.
