4.4 Troubleshooting
PROBLEM: The system will not come up at all, the display is blank and the computer does not make
any beep sounds from the speaker.
First steps if the Board does not boot:
• Check the power connectors to the board, monitor and additional devices.
• Are all cables plugged on the correct connector and in the correct orientation? The board
may not boot if some of the cables are not plugged in correctly!
• Check the power supply. Is the supply voltage correct for the board? If you are not sure,
read the manual. Try plugging in a different power supply or multi-meter to check the
power a wrong supply voltage can easily FRY a computer and other electrical devices.
• Is your display ok? Is the monitor powered on? Is the monitor's video cable plugged into
the video connector? Double-check the brightness and contrast settings. Plug the monitor
into another computer if possible to verify the monitor isn't the problem.
• Apply power to the board while pulling down the BIOS_INIT# signal at pin B95. This will
load the manufacturer BIOS defaults.
• Remove all additional devices from the system. Only the processor board, power supply,
monitor and the keyboard should remain in the system.
• If all else has failed, replace the CPU Board itself.
• If system comes up then load at first the OPTIMIZED DEFAULTS in the BIOS setup and
reboot.
