100 Troubleshooting
Memory Issues
If you have installed incompatible memory modules, the system may not
boot. Verify the memory you've installed has been tested with your system
board. If the installed memory is compatible, remove and reinstall the
memory modules.
Defective memory modules may cause boot errors. To isolate a specific
memory module as defective, boot the system with just one memory module
installed at a time.
Monitor Issues
Monitor configurations can cause boot failure. Run through the following
checklist to verify monitor operation:
• Ensure the monitor is plugged in and turned on.
• Ensure all cables are connected properly between the monitor and the
system.
• Check that the brightness and contrast controls on the monitor are not too
low.
Most monitors employ indicator LEDs showing status. Refer to the monitor's
documentation to confirm operation. If the problem still persists, test or
replace the monitor on a different AC outlet or system.
Power Supply and Chassis Issues
• Verify if the chassis and power supply are compatible with the processor
model.
