Undetermined problems

You are here because the diagnostic tests did not identify
the failure, the Devices List is incorrect, or the system is
inoperative.
Notes
1. If you suspect a software mismatch is causing
failures (solid or intermittent), be sure to see
"Resolving configuration conflicts" on page 36.
2. A corrupt CMOS can cause undetermined
problems.
Check the LEDs on all the power supplies. If the LEDs
indicate the power supplies are working correctly, return
here and do the following:
1. Power-off the computer.
2. Be sure the system is cabled correctly.
3. Remove or disconnect the following (one at a time)
until you find the failure (power-on the computer and
reconfigure each time).
