problems while using your system are listed below.
1. The power switch of each peripheral device is turned on.
2. All cables and power cords are tightly connected.
3. The electrical outlet to which your peripheral devices are
connected is working. Test the outlet by plugging in a lamp or
other electrical device.
4. The monitor is turned on.
5. The display’s brightness and contrast controls are adjusted
properly.
6. All add-in boards in the expansion slots are seated securely.
