^Agreed

From what I can tell, you are saying the computer shut down and said it was trying to prevent damage? This can be a multitude of things, but before anyone is going to be able to help you, we need to make sure what you are saying.

Try to run memtest86+ three times over for good measure. If there arn't any errors, I highly doubt its the RAM.
