• Media in DVD drive during startup
• Corrupt system software
• Missing or faulty DIMMs
• Faulty HDD
• Faulty or overheated CPU(s)
• Faulty motherboard
Suggested action
1. Make sure that no media is in the DVD drive during
startup, and then reboot the system.
2. Recheck all cables and connections.
3. If the problem persists, reinstall the system software
(see
page
132).
Corrupt system software may cause the system to hang
at this screen.
4. Check the DIMMs and reseat them to remove any
oxidation on the connectors (see
that the DIMM configurations in both socket sets are
identical (see
page
100).
5. If the problem persists, test the DIMMs by removing
all DIMMs except for the one installed in J11, and
reboot the system.
If the system boots to Idle, install a different DIMM in
J11 and reboot the system. Continue to install a
different DIMM in the socket and reboot the system
until the system fails to reach Idle. The last DIMM that
you installed may be faulty and should be replaced.
N
:
If the system fails to reach Idle with each DIMM
OTE
installed in J11, the DIMM socket may be faulty and you
may need to replace the motherboard.
