Power Supply Problems

After running a Hitec Digital Hi Torque Metal Gear Servo and a IR sensor on my Arduino, some weird stuff started happening. I tried to plug the board into my computer to figure out why nothing was working, but the "ON" and "L" leds on the board lit up for a second and then quickly faded away. I tried to plug in my 9VDC 650 mA wall supply into the board, which what was I was using when playing around with the sensor and servo, but the same two leds just started flashing, and nothing worked. What's happening? Did I break the board?

Did you connect the servo directly to the arduino output pin?

Show us how the circuit was wired.
