Fried my arduino (at least 13 pins)

G'Day gang,

I'm fairly new to the hardware side and didn't want to post anything till I had something really cool to show, but, well... I think I've fried my arduino. It appears that my LED's hooked up to pins 0-12 will give me a really dim light (if a light at all depending on what LED I'm using), on pin 13 however, it is very bright :). I then figured that it might be my resistor, so I removed it from the equation (I know, I know) but that didn't change anything. My question now is, what have I done/fried? What do I now replace, how expensive is that?

Oahh, and I know it's not a software issue (tested with the following code) Oahh, and pin 0 seems to be fairly decent

void setup()
{
for(int i = 0; i < 14; i++)
digitalWrite(i, HIGH);
}

hits forehead

This is what happens when you don't touch it for a while... Forgot to set pinmode as output...

Thanks xSmurf!
