    I have a MacBook that I bought in 2011.

    Model Name: MacBook
    Model Identifier: MacBook7,1
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2.4 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2
    L2 Cache: 3 MB
    Memory: 2 GB
    Bus Speed: 1.07 GHz
    Boot ROM Version: MB71.0039.B0B

    I bought Crucial RAM:

    2- 2GB 1Rx8 PC3 - 10600S-9-10-B1

    Well when I install it I get beeps and the computer won't turn on?

    I'm no expert but it may be one of three things.

    1)Possibly the wrong RAM - I think that model takes 'DDR3 PC3-8500' type 1066 Mhz

    2) One of the sticks is bad. Take one out and try. If that fails take that out and switch.

    3) You may need to do a PRAM reset (which can't hurt to do in any case) - see below for instructions from Apple how to do that.

    Resetting PRAM and NVRAM
    1. Shut down the computer.
    2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    3. Turn on the computer.
    4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    5. Hold the keys down until the computer restarts and you hear the startup sound for the second time. 6. Release the keys.
    Your computer's PRAM and the NVRAM are reset to the default values. The clock settings may be reset to a default date on some models.

    Ram upgrade

    Well, did you replace both of the two old RAM with new ones? You must keep an old one and add another new one.I have the same model as you. I add a 4GB Samsung one, so I get 5GB.

    The other thing that comes to mind here is seating. The modules take a lot more force to seat and click in properly...Kernel panics are a symptom of this, but you don't say if you are getting these?
