Power – set the DMM to a range that includes 5V DC, then measure on the pins.
I2C – Most modern DMMs have setting where it beeps when it is a short. If not you can just set it to measure resistance. Then (with no power to the board) check the connection between the pins. Also, check that it is _no_ connectivity between SCL/SDA and any other point that looks suspect.
