I fried the arduino mega?

Ok i was using an arduino mega and ramps 1.4 motor controller for my home build cnc.During the time of testing ,there was ahuge back current and probably the mega is fried.

This is the state now,when i plug the mega on to my computer :

1)The Green ON led lights up
2)device detected ,but not recognized.( tried  re installing the drivers ,but no use )
3)Reset button does not make the L light blink.
4)RX-TX not lighting up.

I want to know if this arduino can ever be used again.

And for the safe use of the cnc,what micro-controller/micro-controller precautions/PLC   should be used.


Can i fix this MEGA by replacing some components , i really dont want to spend more on the cnc(i have already spend around 400$ till date)

Pardon me for asking ,but can you please explain what you meant by "I/P Side"

input=i/p

More then likely not - The I/P side is very current sensitive - you may have some functionality but it's not very useful.
