I have a macbook running the santa rosa chipset with the intel x3100 GMA GPU. I purchased 2X2gb ram chips for it last night, but when I put them in, the screen doesn't come on, and i get three beeps and 3 flashes of the LED. If i put my 1 gb back in, it boots right up.
 
Put one chip in at a time to narrow it down.

Same thing happened to me with 2 chips from OWC. Turned out one chip was faulty.

If you try to put one in at a time, try each port as well.

My PowerBook has one port go bad. The other one worked fine. Apple ended up replacing the Logic Board. Now it works fine.
 
What's happening is you are not pushing the RAM fully into the socket.

When you push the RAM in, it goes in 1 inch and stops. You're not done.
Get both thumbs on the RAM and push it harder, it will go in another 1/8th of an inch. If you don't have dents on your thumbs, you didn't push hard enough.

It doesn't 'click', and you can;t see what you are doing, so you have to go by feel.
 
If you haven't already, I would definitely try to carefully re-install them. I had something similar when I upgraded my MBP from 2GB to 4GB (OWC Memory). I carefully removed the 4GB and re-installed it making sure it was seated properly, hit the button and it booted up. I've changed memory before on plenty of machines, so I'm not sure what was wrong the first time, but it never hurts to verify.
