The board doesn't work.

I got the board (UP² Pentium Ultra Starter Package) now. But unfortunately I don't get any display on the screen. The blue LED lights up and the two yellow LEDs of the network interfaces flicker (it doesn't matter if a cable is connected or not). That's all that happens. It also does not boot from a USB stick and the screen does not notice that a device is connected.
What now?

Simply unscrew the heatsink a little bit, and it should work.
