Reliability Monitor is an advanced tool that measures hardware and software problems and other changes to your computer. It provides a stability index that ranges from 1 (the least stable) to 10 (the most stable). You can use the index to help evaluate the reliability of your computer. Any change you make to your computer or problem that occurs on your computer affects the stability index.
The Reliability Monitor is intended for advanced computer users, such as software developers and network administrators.
