Yesterday I saw that I had about 45mb of free memory and the memory started to swap from the hard drive so I rebooted my classic 15" mbp. On the reboot, I can hear the superdrive making the startup noise but the screen is black and there is no startup chime sound. I did a PRAM and SMC reset, swapped out the ram stick on both solts, and tried to boot to safe mode but no cure.
