LattePanda now randomly shutting down.

In the beginning I used the include power supply that was bundle with my LattePanda 2GB RAM and 32GB EMMC storage from the kick starter campaign, which it seem to work okay with. The only issue I had was the fact that if I tried to use the 7" screen, it would show the windows logo, and then shutdown.

Then when I saw a form post that said you could power the LattePanda through the CN2 on the motherboard, I tried that. Which allowed me to get into windows, and then the screen would start going jittery, so I stopped using the CN2 connector and decide to go back to powering it through the micro-USB port.

Now this is when the problem beginnings, as now when I power it through the micro-USB port, it shuts down the second it shows the windows login screen.
Then when I tried it though the CN2 connector it does the same thing as the micro-USB port, it shuts down the second it shows the windows login screen, and sometimes being about to get into windows.

Is there something that I can to make it work, or is the board broken?

Thanks in advance for any suggestions!
