My MacBook won't boot - HDD and fan spin, but no chime!
My Macbook doesn't want to turn on - at all! Pressing the power once causes a few mechanical noises, white light comes on, then within a second powers off again.
If I press a *second* time, it usually stays on, but there is a blank screen, no chime and no response to PRAM/SMC reset or anything.
The hard drive is spinning up, as is the fan.
Battery is charging when connected to mains.
Powering on without the top cover ribbon cable connected is pretty much the same deal, so I don't think it's stuck buttons or anything.
I've tried reseating the RAM, and combinations of different RAM sticks in both slots. Running out of ideas here... :(
