• Ensure that a DVD disc is in the drive with the shiny side of the disc facing down.

• Ensure that video resolution is set to less than 1152 x 864.

• On computers that have a CD-ROM or CD-RW drive in addition to a DVD-ROM drive, make sure that the

DVD disc is in the drive labeled “DVD”.

If these actions do not correct the problem, run the diagnostic programs (see “Diagnostic programs” on
page 108 for instructions). If you need technical assistance, see Chapter 11 “Getting information, help, and
service” on page 111.

Intermittent problems

Symptom: A problem occurs only occasionally and is difficult to repeat.

Actions:

• Verify that all cables and cords are securely connected to the computer and attached devices.

• Verify that when the computer is on, the fan grill is not blocked (there is air flow around the grill), and the

fans are working. If airflow is blocked or the fans are not working, the computer might overheat.

• If SCSI devices are installed, verify that the last external device in each SCSI chain is terminated correctly.

(See your SCSI documentation.)

If these actions do not correct the problem, run the diagnostic programs (see “Diagnostic programs” on
page 108 for instructions). If you need technical assistance, see Chapter 11 “Getting information, help, and
service” on page 111.
