STM32F4 Discovery not working without reset

I have an STM32F4 Discovery board; recently I just had uploaded some code pertaining to the PWM example where I made PD12-15 some PWM signal so I could see it working with the LEDs on board.

The program uploaded and now the board is not detected unless I hold the reset button. In Windows the device is said to be unknown. When holding the reset button the device comes up and after uploading the discovery code it does not change the behavior of the board.

Without pressing the reset button the board just acts the same no matter how much I program it.

Any help would be appreciated.
