How do I fix my machine???

I have a he3d ei3 tri color 3d printer and its not working properly. I get 2 or 3 layers and it starts to skip layers as it prints. The bed plate stays hot... it gets up to over 100 ° C and I have no control over that. It actually melted my roller carriage holding the bed plate. Not sure what to do. And to top it off... i can't transfer g code files from my sd card... it just goes from 0 to 100% in seconds without having any movement from the machine.
