1. Boot from the diagnostics diskette and start the PC
Doctor program (please refer to “Running the PC
Doctor Diagnostics Program” on page 135).
2. Run the System Board test to verify the symptom.
This test verifies both the system board.
If the tests detect a system board problem, replace the
system board.
