Unhappy Macbook 1278 RAM problems

Hey all-

I have an aluminum unibody Macbook that all of a sudden is giving me the 3 beeps indicating bad RAM. If I remove both sticks, I get the one beep indicating that there's no RAM like I expect. But, if I put any RAM into either slot, 3 beeps. Even with known good RAM. It was running for a while with just the bottom slot working, so I bought a new Crucial 4 gig stick, and put it in the bottom slot. It booted once, then the next time I tried to boot it made kind of an alternating POST chime / weird screeching sound / POST chime / screech sequence until I held the power button to shut it down. Now, it won't boot at all. Anybody have any ideas?
