I would first checking the power supply. The disk drives motors may be
operating ok if the regulated 12 volt supply is OK but I suspect that the
regulated + 5 volt supply is not working. That power is used to power most
of the cards, motherboard (and LED's on the motherboard) and drive logic
circuits. The same +5 volts gives the beeps too!
If you have volt meter you can check the power at one of the drive power
connectors. If you don't have a volt meter, the power supply is one of the
cheaper items to replace ($30 - 40 US).
Good luck,
