CAUTION:

Many repairs may only be done by a certified service technician.

You should only perform troubleshooting and simple repairs as authorized in
your product documentation, or as directed by the online or telephone service

not covered by your warranty. Read and follow the safety instructions that
came with the product.

Invalid memory configurations can cause your system to halt at startup

without video output. See "General Memory Module Installation Guidelines" on

page 122 and verify that your memory configuration complies with all applicable

guidelines.

1 If the system is operational, run the appropriate online diagnostic test.

See "Running the System Diagnostics" on page 169.
If diagnostics indicates a fault, follow the corrective actions provided by

the diagnostic program.

2 If the system is not operational, turn off the system, including any

attached peripherals, and disconnect the system from its electrical outlet.

Wait at least 10 seconds, and then reconnect the system to power.

3 Turn on the system and attached peripherals and note the messages on the

screen.
