    Did you try zapping the PRAM  ?

      And then doing an SMC RESET ?

        couldn't hurt to try..

     

    Command-Option-P-R keys at Startup..

    After zapping PRAM.. Unplug the power for 30 seconds.. Then restart it..

      SMC reset..

    1)  It is Important to get the Correct and Matching RAM

     

    Use this Link to check which RAM is suitable for your Mac...

    The site also have videos on how to Install RAM should you need it...

    2)  Check that the RAM is seated correctly.

     

    3)  Try it with only the Original RAM installed.

    Mac's are very picky when it comes to RAM.

     

    1. Did you get the correct RAM modules specific to your model?

     

    2. If so, did you make sure to fully seat the modules into the slots before locking them down into the clips.

    den.thed & AnaMusic pretty much nailed it. Your RAM is the wrong spec or possibly one or both are defective. Being improperly seated may be a possibility but typically that just results in the RAM not being recognized at all.

     

    Use AnaMusic's link to make sure your RAM is the correct kind. Just because it fits the slot doesn't make it right. If the RAM is the right kind then the best thing to do is to insert 1 chip and boot. Then insert the other and boot. If the computer starts up both times then insert both and boot. If it boots okay again then probably it was indeed a perfectly mis-seated chip. If it doesn't boot this time then return both to the vendor because one or both are marginal and there's no way of telling which is the problem.
