Preliminary Steps.

2. Run the Power-On Self-Test (POST).

3. Follow the recommended actions described in the diagnostic

tables, if you are unable to run POST or if POST displays an

error message.

listed. Rerun POST after each recommended action until the

problem is solved and no error message occurs. Once the

problem is solved, do not complete the remaining

recommended actions.

If the problem is intermittent, check the computer

several times to verify that the problem is solved.
