regular beeping sound every 4 seconds with the sleep LED blinking
I am also having a similar issue. When starting up, I get a regular beeping sound every 4 seconds or so with the sleep LED blinking. I reset both RAM sticks but had the same problem. Interestingly, when I leave the lower (looking at the backside of the macbook) slot empty, I don't get the beeping sounds but still the computer won't start. Screen stays black and the fan is doing its rounds. Any idea what the problem might be?
Thanks for your help!
Is this a good question?
