So the cord and graphics card came today, I turned it on only to be greeted by 3 beeps. According to the Service Manual, "3 Flashes: No RAM banks passed memory testing." I immediately took out the RAM to see what may be wrong and just left the 2x 256mb sticks, and got 2 beeps, "2 Flashes: Incompatible RAM types are installed or RAM installed in wrong slots." When I only left the 2x 1GB sticks, there were 3 flashes again. So I think that it may be the RAM, but the slots themselves are a possibility. The 2x 256MB sticks are PC2-3200 and the 2x 1GB sticks are PC2-5300.
