macbook is not starting at all
Dear All,
My MacBook white (early 2008) was working properly , but one day it stopped and started beeping. The reason was one of the RAM was damaged, and I changed it. after few months again it is stopped and started beeping. I again changed the RAM.
But this time it is not starting at all. When i press start button, there is just black screen and no starting tone. All I can observe is spinning of hard disk and fan. I tried few pairs of RAM, but result is same.
Also , i tried all possible shortcuts of booting options. But the MacBook is not responding to any of them. I have lion bootable USB, but system is not booting with it. it is just black screen all the time.
Please help me, if my MacBook can work again.
MacBook (13-inch Early 2008), Mac OS X (10.7.2)
