Memory Diagnostics

If you have relocated any memory addresses, you must change the addresses to their original locations before running the memory tests or they will not work properly.

If an error occurs during a memory test, the program displays this message:

Press <Enter> to view faulty memory chip.

Press Enter. The program displays a diagram of the main system board and highlights the faulty memory chip.

Hard Disk Diognostics

Hard disk diagnostic tests may be destructive or non- destructive. Destructive diagnostics destroy data on the hard disk, but non-destructive diagnostics do not. Be sure to back up any data on your hard disk before performing any destructive tests. The following table lists which tests are destructive and which are not.
