• If you have defective memory modules, the system may not boot. One, two or three beeps at boot indicate
defective memory. To isolate a specific memory module as defective, boot the system with just one
memory module installed at a time.
Monitor Issues
No boot situations can be caused by monitor configurations. Check the following:
• Make sure the monitor is plugged in and turned on.
• Make sure the video cable is connected properly at the monitor and the computer.
• Check the brightness and contrast controls on the monitor. The monitor may be dimmed where you
cannot see anything on the monitor.
• Most monitors have a light indicating its current status:
• A green light indicates the monitor has sufficient power and is getting a video signal.
•
An amber light appears if the monitor has power but it is not getting a video signal
from the computer. This indicates the problem is most likely in the computer.
• If the light does not turn on at all, it is likely a problem with the monitor itself. Make
sure that the monitor is connected to a working AC outlet. If there is an on/off switch
for the outlet, make sure the switch is on. If the problem still persists, try replacing
the monitor or try the monitor on different AC outlet or a different system.
Power Supply and Chassis Issues
No boot situations can be caused by any of the following power supply, chassis or fan issues:
• Verify that your chassis and power supply is appropriate for the processor model and frequency and the
motherboard you have.
• Verify that the power supply has the capacity to power all the devices used in your system.
• Ensure the power cord is firmly connected to the power supply and the AC outlet.
• If the power supply or the AC outlet has an on/off switch, make sure that it is on.
Cable Issues
No boot situations can be caused by any of the following cabling issues:
• Make sure the drive ribbon cables inside the computer are attached correctly and securely.
• Check that the cables connecting the chassis back panel to the motherboard are plugged in properly to
the onboard headers.
