What just happened? Can my H-bridge not handle the load?

I used the sketch stepper_oneStepAtATime.ino to test and check if all my wiring is right, and that is when the H-Bridge wend up in smock. Note, I am using pin 7 through 10, not 8 through 11 as suggested in the original sketch; but that should not matter.
#include <Stepper.h>
const int stepsPerRevolution = 200; // change this to fit the number of steps per revolution
// for your motor
// initialize the stepper library on pins 8 through 11:
// >> I am using pin 7 through 10 - not 8 through 11:
Stepper myStepper(stepsPerRevolution, 7, 8, 9, 10);
int stepCount = 0; // number of steps the motor has taken
void setup() {
// initialize the serial port:
Serial.begin(9600);
}
void loop() {
// step one step:
myStepper.step(1);
Serial.print("steps:");
Serial.println(stepCount);
stepCount++;
delay(500);
}
