    Heard this twice now. First time I heard it a few weeks ago I was in Windows via Parallels and just thought that was it. It hadn't done it again until tonight. I was just watching a video, the screen scrambled and then 3 long beeps followed by a pause then 3 long beeps, etc.

    My MBP boots as normal and all is fine now.

    Getting conflicting info on what 3 beeps means. Memory? 6 months ago I upgraded from 4gb to 8 myself. I'll check the modules if that's what this sound code means.

    Three long beeps typically indicate faulty memory, have you tried running the Apple Hardware Test or another a memory testing tool such as Rember?

    Can't run Apple's Hardware Test for some reason. Tried Rember and all tests passed.

    Strange.

    Hey.

    Try taking out your RAM, and then puttting it back in. I had similar random problems with my macbook, the memory sticks might have shifted a tiny bit.
    but really make sure you do it correctly, guides are easy to find...

    Yep. Good advice. I'm wondering if when my motherboard heats up maybe the socket is swelling just enough to cause a loose connection.

    Yeah reset the position of your RAM and then try PRAM reset
