Macbook will not boot

I have a macbook that will not boot. This is a 2008 aluminum macbook.  When i boot the machine it beeps 3 times.  Which according to other articles has to do with the RAM.  I tried reseating the RAM.  

When I did that now the Macbook just goes the the grey apple screen and reboots itself.

Any ideas?

The RAM could be faulty. Remove a stick of memory and try to boot, swap if unsuccessful. If it boots without one module,the RAM itself is faulty.


I tried changing out sticks of RAM. when I do that the beeps go away the machine still boots only to a grey screen.  

I tried the Pram, nothing changed

I tried booting to the system disk, It boots to a blue screen but that is as far as it goes. Its doesn't allow you to do anything.

Do the beeps go away with either of the sticks of ram out or just one?

if you manage to get no beep, hold down shift for safe mode and see how far you get with that. This will load just basic kexts which if successful indicates a software problem.


The beep goes away with either sticks of RAM out.  When they are together it comes back.  As for the boot in safe mode I can't seem to get there.  I also can not get the CD out.  I am not sure if that is preventing this issue or not.

To get the CD out, hold down the option key and boot.  A boot menu should appear, when it does, hold the F12 key to eject the media or click on the eject icon if it appears on the screen.

if only one stick of RAM is working, you have possibly bad RAM or a bad memory slot on your logic board which would require you to your system to a an ASC


I went out and bought new ram.  Still does not boot.  I did finally get the CD out using the option key.

Just does the apple grey screen and eventually reboots

Ok next do this open the disk utility and do a check and fix permissions.

After that is done, do a check repair disk.


RAM was bad but so was the hard drive.
