About PC Check Lab

PC Check Lab is a set of free tools that help gamers, streamers, musicians and everyday computer users check their hardware in seconds.

We built these tests because finding out whether a controller, mouse, microphone or graphics card is really faulty should not require downloading unknown software. Every tool runs directly in your web browser using standard web technology, so it is fast, safe and private.

Our principles

• Privacy first – your device data and audio stay in your browser.
• No installs – everything works from the page.
• Plain answers – clear results and practical fixes, without jargon.

Our Editorial Policy explains how we build every tool, check each guide against trusted sources and correct mistakes quickly.

Our hardware guides are written by Oliver Bennett, who checks every fix with our own browser tests before it goes live.
