No catch up TV, recordings or Internet channels

Hello,

Since Monday morning we have been unable to access any of our internet channels (Sky 1 etc) and I have also noticed we cannot access any of the catch up TV services (iplayer or 4od etc) and recordings are no longer happening saying that the program cannot record as it has "finished" before it has even started recording

The box has also failed to start up on a few occasions, I have tried every method listed but it fails to start up each time unless I turn it off and on again, changing channels can sometimes freeze the TV as well, it also sometimes doesn't bring the guide up.

Any Help?
