The System Health Report is one of the most useful diagnostic tools in Vista. It takes input from the Performance and Reliability Monitor and turns it into a well-organized, information-packed report that does a good job of spotlighting potential problems. To run this report, open Control Panel, click System and Maintenance, and then click Performance Information and Tools. In the Tasks list along the left, click Advanced tools. The last item on the resulting list is Generate a system health report.
