Troubleshooting
CPU Frequency Ratio
The system did not boot up with the frequency ratio I selected.
Selecting a higher frequency ratio may result to the CPU’s or
system’s instability and are not guaranteed to provide better system
performance. Power off the system and set SW1 pins 1-5 to Off
(Auto).
Monitor/Display
If the display screen remains dark after the system is turned on:
1. Make sure that the monitor’s power switch is on.
2. Check that one end of the monitor’s power cord is properly
attached to the monitor and the other end is plugged into a
working AC outlet. If necessary, try another outlet.
3. Check that the video input cable is properly attached to the
monitor and the system’s display adapter.
4. Adjust the brightness of the display by turning the monitor’s
brightness control knob.
The picture seems to be constantly moving.
1. The monitor has lost its vertical sync. Adjust the monitor’s vertical
sync.
2. Move away any objects, such as another monitor or fan, that
may be creating a magnetic field around the display.
3. Make sure your video card’s output frequencies are supported
by this monitor.
The screen seems to be constantly wavering.
1. If the monitor is close to another monitor, the adjacent monitor
may need to be turned off. Fluorescent lights adjacent to the
monitor may also cause screen wavering.
Power Supply
When the computer is turned on, nothing happens.
1. Check that one end of the AC power cord is plugged into a live
outlet and the other end properly plugged into the back of the
system.
