    I recently upgraded my Unibody Macbook to 4gb of ram, and have had numerous problems with the computer freezing and the screen displays green or red dots everywhere, sometimes the speakers play a high pitch sound. I was wondering if anyone has had similar problems or any suggestions.
    Thanks for the help.

    The green/red dot problem sounds like the GPU overheating.
    Get it serviced.

    I suggest going to a genius bar or calling apple care to set up a repair/exchange.

    If you recently upgraded your RAM, and now you're having the problem, why not put the old RAM back and see if the problem goes away? If it doesn't, you'll know the problem isn't the RAM, wheras otherwise you wouldn't.
