Is your computer operating at its maximum efficiency? Windows Vista can let you know for sure. Just check out the Reliability and Performance Monitor, which you will find in Control Panel > System and Maintenance > Performance Information and Tools > Advanced Tools > Generate a system health report. Windows will check your disk drives, drivers, services, software and hardware configuration, and more to give you a full accounting of what might be causing you trouble. If it finds a problem, it will explain it to you in detail and suggest how to resolve it.
