So I was trying to plug in something into the USB port and it wasn't fitting properly. So I lost my temper and forcibly jammed the cord into the USB port, which caused some kind of short. There was a plastic burning smell and then the computer shut off. I tried to push the on button and the button briefly lights up, but the computer still doesn't turn on. I opened up the cube and hit the rest PMU button. That didn't work... I'd appreciate any suggestions.
