For 2 days now my HD Box keeps rebooting on its own, comes back on but I can’t do anything on the remote then robots again then comes up with Shaw login error will retry in 5 mins etc. Over and over. Tried unplugging but it does the exact same thing again. Box screen says PSLd but it also resets to 24hr time. 

How can I fix this? It’s extremely annoying considering the amount I pay for service every month.
