WELCOME to PC Pitstop OverDrive

Just park your PC and grab a cup of coffee. Our automated mechanics will put your PC safely through a battery of tests to check its health, configuration, and performance.

In addition to ensuring your PC is running at maximum performance, we also help you eliminate potential issues that may cause headaches down the road.

This online diagnostic takes between one and five minutes to complete depending upon your system and internet connection. You will see real time updates on the progress and status of our tests, and when finished a 'clickable' report on your PC's health and performance.

We keep all the information you give us private. See our privacy policy for full details.

Remember: The tests do not change any settings (unless you say so) or access any private data. Read more about why our tests are safe.
