Application software problems
Make sure all cables are installed correctly.
Verify that your system hardware configuration is set correctly. In Setup,
check the values against the system settings that you previously recorded. If
an error is evident (wrong type of drive specified, for example), make the
change in Setup and reboot the system. Record your change.
Make sure the software is properly configured for the system. Refer to the
software documentation for information. Try a different copy of the software to
see if the problem is with the copy you are using.
If other software runs correctly on the system, contact the vendor of the failing
software.

Make sure your system's video adapter card is installed, enabled. Reboot the
system.
