Is there anything you can unplug from the ramps side of the power plug? Or to trouble shoot unplug everything but the drivers you are using and the steppers, nothing else. I am guessing you have an lcd plug that in next, it is probably the culprit. They draw a lot of power sometimes.

On one of my sdcards the card gets hot pretty fast and really cooks my arduino so I threw it away no problem since.
