Turn off computer and disconnect
power. Replace components in
system one at a time starting with
hard drive. Test system after each
replacement for video or beeps.
Notes:
1. System boards without a piezo speaker, or chassis
without an internal speaker require an external
speaker.
2. Some power supplies require a load greater than
the system board alone to function properly. When
disconnecting drives, disconnect the data cables
but leave the power cables attached.
3. Remove auxiliary video card if integrated video.
4. Remove cache module on Deskpro 2000 models
(if installed).
