Depending on the beeps, you can actually know quite a bit. The most common cause is a Video Card but on a Mac it not turn on and beep three times, to indicate a RAM issue.


So A: Wont POST,wont Beep?


Its can still post with a dead or missing CMOS battery


I don't quite understand. Isn't the power on self test (POST) the reason for the beeps?
