Disclaimer
Please read this page to understand what our browser hardware tests can and cannot tell you.
Last updated on 19 October 2026, this Disclaimer adds to our Terms of Use, which govern every visit to PC Check Lab.
Test Results Are Indications
Our gamepad, mouse, GPU, microphone and MIDI testers read data that your browser shares through standard web features. Results depend on your browser, operating system, drivers and connection, so they give strong indications rather than certified diagnoses. Browsers cannot read sensor data such as temperatures, fan speeds or hard drive health, and our pages say clearly where those limits apply.
GPU Stress Test Safety
Our GPU test places a short load on your graphics card, much like a game scene would. Modern graphics cards protect themselves from overheating, and our test stops after 20 seconds or whenever you switch tabs. Stop any test straight away if your device behaves unexpectedly, and avoid stress testing hardware that already shows overheating or physical damage.
Repair Advice
Fixes on our pages, such as cleaning sticks with compressed air or raising debounce time, come from common and widely shared practice. Opening controllers, mice or other devices may void manufacturer warranties, so check warranty terms first and ask a qualified repair service when unsure. We are not responsible for damage caused by repairs or changes you make to your hardware.

External Links and Ads
Our pages link to outside sources such as MDN Web Docs and W3C specifications so you can check technical details yourself. We do not control those websites or any ads shown on our pages, and we are not responsible for their content, accuracy or privacy practices.
