Online Computer Diagnostic Scan


Free, Fast & Easy


Detects Most Common Problems


Anonymous & Safe


Optional Updates & Alerts

Using our ScanCircle tool, you can get a diagnostic report of your computer in just 10-15 seconds.

The scan checks for most common problems by scanning the components, operating system, security, hardware, drivers, software and processes, and then provides a full report of issues which need to be fixed and suggestions on what could be improved. The scan results are clearly explained and easy to understand for all computer users, and are ordered by importance, so that you can attend to the critical issues first.

The scan does not make any changes to your computer, and does not retrieve any personal details. You can choose to subscribe to receive alerts when new updates are available for your device.
