Black screen on Congo jr.

Hey guys,  

On one of our Congo Jrs when it boots up it will only boot into a black screen... but a mouse will appear.

My thought process is that windows is loading correctly but for whatever reason, cobalt will not load. 

Could this be a possibility? if not any ideas.  Also what could be some fixes.

P.S.  I did do a hard power reset 3 times to try to let it retry.
