do you say that even if you power the board via USB you get this problem?
Yes any power given to the Arduino causes this issue including battery, regulated power supply, and usb.
so you should check all wires and maybe there is some metal on the back of the board that should not be there?
I don't have the board connected to any circuit, just powering it causes this issue. It was working fine before, but then this issue abruptly occurred when I was running some code on the Arduino. As far as I can tell there is nothing wrong with the board, I didn't even smell or see anything get damaged when this first occurred. I also have another Duemilanove and compared it to this one and saw no difference.
