Why We Built This Platform
Historically, diagnosing computer peripherals—such as discovering whether a mouse switch suffers from double-click chatter, whether a gamepad has analog stick drift, or whether a microphone is receiving acoustic signals—required downloading suspect third-party utility software or navigating deep into operating system device manager settings.
We created PCGearCheck to make hardware verification accessible, fast, and secure for everyone: gamers testing gear before a tournament, IT technicians evaluating customer laptops, and second-hand equipment buyers inspecting used gear.
