macbook starting issues

Hey, I am new to mac's and am having issues. I currently have 2 macbooks... never really had any trouble


both have recently have leopard installed. I was about to transfer files over between the two, so one was on screen saver as I wasnt using it. When i went to pick it up it restarted for some reason. Then it did the usual apple logo and load up - and went to a black screen making the eject disk noise over and over. This is where I am stuck now, black screen with a constant eject noise.


I tried taking out the battery, resetting, powering on numerous different times.... nothing is working.

Any help is appreciated!

Try resetting the PRAM and NVRAM on your MacBook:

hmm okay. recent update.... out of frustration i hit the palmrest pretty hard when the eject noises were going.... it stopped so i restarted the computer and it boot up!!!!!! i went to go do a software update (hoping that it would fix any issues i was having) and just as the toolbar was pretty much all the way the computer restarted again..... it then booted up to a message on the desktop saying that i needed to restart.... and now im at the same black screen with the eject noises..
