PC Health Check & Troubleshooting

Here it means a collection of limited browser checks, organized by symptom. You can review approximate memory, site storage, a simple rendering scene, local audio, display colors, and HTTP response times. It is not a complete examination of your PC.

Yes. No account, installation, or payment is required. Opening the site and running the external HTTP check still use your internet connection and may incur normal data charges.

No. A browser cannot inspect every process, driver, hardware component, or operating-system setting. The tool helps you choose a useful next check; it cannot identify every cause or repair the problem.

No. It is an approximate value supplied by the browser, which can be rounded, capped, or unavailable for privacy reasons. It is not your current RAM usage or proof that you need a memory upgrade.

No. The estimate concerns browser storage used by and available to this site. It does not read your whole drive, free disk space, SMART data, SSD wear, or disk health.

No. It does not measure CPU performance or overall system load. Approximate memory and site storage are limited browser observations; they cannot identify every cause of slowness or determine whether you need a hardware upgrade.

It counts rendered frames in a simple browser scene. Browser settings, display timing, power mode, background work, and graphics support can affect it. It is not a GPU benchmark and does not predict video or game performance.

The browser may lack usable WebGL support, restrict graphics acceleration, or fail to load the existing rendering library. Review browser settings or compare another supported browser. This alone does not prove that your GPU is faulty.

Choose the audio symptom, select Start microphone test, and grant permission if you want to continue. A local waveform shows received audio. A moving waveform does not prove that another meeting app is using the correct microphone.

No. The app draws the waveform locally and does not record or upload microphone audio. Stop the test when finished. Changing symptoms, changing languages, or leaving the page stops access; a late permission response is also cleaned up.

The app shows an unavailable message. Check site permissions, the selected input device, and operating-system privacy settings, then retry if appropriate. Other checks remain available without microphone permission.

After you select Play test tone, the browser plays a 440 Hz sine tone for about one second. Lower your volume first. If you hear nothing, check mute, output-device selection, connections, and browser permissions. It is not a hearing test.

They help you visually look for pixels or uneven areas while cycling red, green, blue, black, and white across the browser viewport. The test cannot confirm the cause or repair pixels. Press Esc or use the exit button to finish.

No. It times five HEAD requests to the existing Google logo URL and displays their average and average consecutive difference. Browser overhead, caching behavior, server conditions, and the route can affect the result. It is not ICMP ping or a speed test.

No. It keeps the chosen symptom and displayed reference values. Active microphone, tone, rendering, and network work stop safely. Resume or start a check again only when you choose to do so.

No. It does not scan files, inspect operating-system security, detect malware, or certify safety. Use the security tools and support appropriate to your device for those tasks.

The interface adapts to smaller screens, but the symptom guidance is intended mainly for computers. Available information, microphone permissions, and rendering support vary by browser and device. An unavailable feature does not itself indicate a fault.

Use the dedicated English guides linked below and beside the related symptom. They cover keyboard chatter and rollover, mouse clicks, gamepad input, touchpads, displays, and network observations. Each tool describes its own limits.
