Checkmate is a computer health-monitoring application by Micromat. We created Checkmate to be a powerful computer-diagnostic product without being an intrusion to your work. The software observes your schedule and performs testing when your computer is idle. It then quietly logs results and stays completely out of your way - unless it finds a serious problem. Then it will alert you to the issue, and will open the Checkmate dashboard so you not only get a full report of the issue, but also are presented suggested steps you can take to correct the problem.

And Checkmate couldn't be simpler to use: simply install it
