View Reliability Monitor History

When your system's acting flaky and you're trying to figure out what's going on, the Reliability Monitor may help. Click on the Start button and type in 'reliability'. Click on 'View Reliability History' to see a graph of your system's stability index over a period of days and weeks (rated on a scale of 1 to 10). It displays which programs, Windows components, or miscellaneous items crashed on a given day, helping you identify problem items.
