Solution
Turn off the computer, turn on the external device,
then turn on the computer to integrate the device
with the computer system.
Reboot the computer and follow the instructions for
accepting the changes.
Use Windows Device Manager to deselect the

basic configuration that does not cause a resource
conflict. You can also use Computer Setup to
reconfigure or disable devices to resolve the
resource conflict.
Enter Computer Setup (F10) and enable the USB
ports.

system to determine if you are using the
correct memory modules and to verify the
proper installation.

installed.
2. Observe the beeps and LED lights on the
front of the computer. Beeps and flashing
LEDs are codes for specific problems.
