STM32F429 Discovery OverCurrent LED

Hi everyone.

I'm not sure what I did, but my F429 Discovery board is drawing way to much current. The overcurrent light (LD6) turns on when I supply the board with power and U8, which I believe is a power distribution switch, gets very hot. The board still functions, and I can still draw on the LCD with the simple paint program I was testing. Does anyone know if my board is toast or if I can replace some component/s to save it? 

A bit of background if it helps:
Tried powering the board through a 5V regulator connected to an external power supply to the 5V pin. At this point, I noticed the current being drawn from my power supply seemed to be a lot (600mA). While trying to diagnose my circuit, I accidentally touched a wire from either the 5 or 3V pin to ground, and after that my board has been acting the way I just described. Any help would be appreciated.

Thanks

Stone
