115Installation and Service Guide: Color Controller E-85
Troubleshooting
Startup (continued)
System hangs during
Windows control of startup,
during or after the Windows
logo screen.
See previous page. (Continued from previous page.)
7 If the problem persists, verify the CPU and CPU fan
connections, and verify that the CPU heatsinks are
securely installed (see page 69).
Test the CPUs by removing the CPU installed in socket
CPU1 and rebooting.
• If the system fails to boot up properly, the CPU in
socket CPU0 is faulty and should be replaced.
• If the system boots up properly, the CPU in socket
CPU0 is good and the CPU that you removed from
socket CPU1 may be faulty. To test this, remove the
CPU from socket CPU0, install the other CPU in
socket CPU0, and reboot. If the system fails to boot
up properly, the CPU currently installed in socket
CPU0 is faulty and should be replaced.
8 If the problem persists, you may need to replace the
motherboard (see page 56).
If replacing the motherboard does not correct the
problem, make sure you reinstall the old board in the
E-85.
