Black screen with single repeated beep -- not starting up

I have a 2010 MacBook Pro that will not start. I have tried an SMC reset as well as a PRAM reset with no results. Battery removed and reinstalled with no effect. Ram removed and reinstalled as well. Any suggestions? Or are we talking a new mother board?

Answer this question I have this problem too

Is this a good question?

One tone, repeating every five seconds: No RAM is installed.

What is the history of the machine and what type of RAM is in it?
