Wont boot past grey screen with no logo, chimes over and over
My customers 13" MacBook White will not boot up at all. Only a Grey screen, you get the first chime then it just keeps chiming over and over again but the rest are not as loud. I have removed the hard drive no difference. I have removed the memory and that's the only time it wont boot to a screen like expected. I have also tried one memory stick. The only key stroke that works is apple,option ,p,r but after it reboots it still the same thing.
So I have a Chime, Grey screen with NO LOGO, or POINTER btw. And constant chime at lower level after. I think its the board please tell me whats going on.
Owner states he thinks he got a virus on it, then the baby started hitting buttons. After a reboot machine never came back up. But i think I ruled that out by getting the same effect by removing the hard drive.
BIOS / Firmware problems? I have 18 years pc repair my first attempt at mac.
