Using Advanced System Diagnostics

Advanced System Diagnostics allows you to run diagnostic tests to determine if the computer hardware is functioning properly. The following diagnostic tests are available in Advanced System Diagnostics:

●Start-up test—This test analyzes the main computer components that are required to start the computer.

●Run-in test—This test repeats the start-up test and checks for intermittent problems that the start-up test does not detect.

●Hard disk test—This test analyzes the physical condition of the hard drive, and then checks all data in every sector of the hard drive. If the test detects a damaged sector, it attempts to move the data to a good sector.
