Make sure the SPEA board is firmly seated in its expansion slot, and that it is not touching other boards in your system.
Be sure your monitor cable is properly connected to the SPEA board and that your monitor power switch is on. You may also need to verify your cable pinout, since some monitors use a non-standard configuration.
Recheck your computer's switch and jumper settings.
Run the SPEA board Diagnostics Program (S3TEST.EXE). It is located in the directory C:\SPEA\GDC.
Make sure other peripherals such as EMS cards, disk controllers or LAN cards are not using the same memory address as the SPEA board. Check with the manufacturer or your user's manual for information about designating exclusions for memory locations when invoking your device driver.
