PowerPC :: Repairing EMac 1.25 - 3 Beeps After Capacitor Replacement

have been repairing a 1.25 GHz eMac with the documented capacitor plague problem, and have managed to replace the capcitors within the logic board, however now when I attempt to boot up the eMac it gives 3 beeps and will not start, having looked up the condition I found it meant that it could detect no good RAM, so I purchased a 1GB DIMM from OWC and replaced the 2 x 512MB sticks in there previously, however the problem still persists and the machine won't boot.
