I have had a similar problem. My box froze on boot up and then after i tried powering it down and backup it came up with a message that the HDD was not formatted and to click on yes to proceed. I had not other option than to go ahead and reformat the HDD.
From then on on every boot up, it cam up with the same message. I eventualy had my box replaced with a new one. The old one had lasted 2 months!
During talking to the "Argos Technical" team they told me to turn the power off by the switch at the rear then to press and hold the power on button for at least 30 seconds whilst then turning the power on by the switch back on at the rear to force a hard reset.
They seemed to think that it would work in the same way as a sky box. It never worked for me, though it may work for you, but I would not hold out much hope.
Good luck
