What browser-based checks can tell you
OnlinePCTest is a collection of browser-based tools for quick PC and laptop checks, with no app installation. Camera and microphone checks require permission. The tools use input, output and information available through your browser; browser and operating-system limits affect what they can detect. Results can help with troubleshooting, but do not replace professional hardware diagnostics.
