Mine came in yesterday, I set it up and it was working fine.

Overnight it stopped hashing. A reboot brought it back. Was working fine for a little while (no idea how long) and I got an offline message from litecoin pool again.
Changed pools, added pools did some other things. Now I am getting massive HW errors after the last reboot.
Made no changes to any of the settings just the pools.
Power supply has more then enough power to run it so I know that is not it:
(I cut the pool URLs out of the image but they are there)


Any thoughts on what to check?

Thanks,
Dave
