Raspberry Pi won't boot

HI, our new raspberry pi won’t boot. We are powering it via a USB cable connected to a laptop. We know it is getting power because the red light near the power cable is on (see below). The HDMI cable is connected to a monitor that we know is working. We tried it while connected to the GoPiGo board and by itself. I am concerned that the SD card slot has a connector wire loose. If you look on the picture below there appears to be a loose gold wire showing through the small opening in the SD card slot.

Any help would be appreciated!

Hmm. What are you seeing on the monitor when you’re attempting to boot? Also is it a Pi2 or 3?
