If possible, back up the contents of the systems hard drive to some other media before removing the system board. Also, record the CMOS configuration settings, along with the settings of all jumpers and switches, before exchanging the system board.
Remove the video and disk drive controller cards from the system boards expansion slots. Disconnect the system board from the power supply unit and the system board front panel connections. Take care to make any connection removed from the system board, and its connection point, to ensure proper reconnection. Exchange the system board with a known good one. Reconnect all the power supply and front panel connections to the system board. Reinstall the video and disk drive controller cards in the expansion slots and try to reboot the system.
Reconfigure the system board to operate with the installed peripherals. Reset the video and disk drive controller cards in the system unit. Reset the CMOS setup to match the installed peripherals and turn on the system.
When the system boots up, reinstall any options removed from the system and replace the system units outer cover. Return the system to full service and service the defective system board. If the system still does not boot-up. retest all the system components one at a time until you find a cause. Check the small things such as cable connections and key switches carefully.
