Troubleshooting
n
Reconfigure the computer after installing a nonplug and play
expansion board or other option. See "Solving Hardware Installation
Problems" for instructions.
n
Be sure that all the needed device drivers have been installed. For
example, if you are using a printer, you need a driver for that model
printer.
¦
Remove all bootable media (diskette, CD, or USB device)
from the system before turning it on.
n
If you have installed an operating system other than the factory-
installed operating system, check to be sure that it is supported on the
system.
n
If the system has multiple video sources* installed and a single
monitor, the monitor must be plugged into the monitor connector on
the source selected as the primary VGA adapter. During boot, the
other monitor connectors are disabled and if the monitor is connected
into these ports, the monitor will not function.
CAUTION:
When the computer is plugged into an AC power
source, there is always voltage applied to the system board. You
must disconnect the power cord from the power source before
opening the computer to prevent system board or component
damage.
