Checking the Installed Devices List

If a device is installed but its icon appears in gray shade rather than in dark shade on the basic diagnostics test

menu, the device is defective. Reseat the device connectors. If the symptom remains, replace the device or the system board. If needed, adjust the contrast control to clearly distinguish the shades of the icon.
