problem installing - OrangePiPC

I have installed Dietpi on a SD card and manage to get logged and it started to update, after that a message appeared saying that i should reset it and log again and everything would be fine, it shut down but did not started up again. please help

Hi,

I tested our v127 OPi PC image (latest http://dietpi.com/downloads/images/DietPi_OrangePiPC-armv7-(Jessie).7z), seems to be working fine here.

Its most likely a unstable PSU and/or corrupt filesystem.
Can you please try downloading the image above, then, write it to a different SDcard (if possible)?
