My remote has suddenly stopped working. If I turn the box off and on again the remote works for a couple of minutes and then dies again. Help!!!

Guide to updating via PC:

Several times since the last software update this has happened. I turn on and press the guide. Sometimes there is no info. and I get the rotating "I'm thinking" icon. This just sits there. If I am lucky I can come out of the guide. Whether I can, or not, I then find that none of the buttons get a response
I can't call up recordings, or the guide. I can't even turn over the channels. I have tried a full switch off & on again. After reloading everything it is still stuck on the one channel.
If I then leave it, after about 15/20 minutes it suddenly works normally. Any ideas?

My 2 year old box worked ok until my wife started deleting 300 files of unwatched soaps. The box still receives and continues to give all functions except record and delete. When watching tv the deleting icon, revolving circle, is displayed at all times and no matter what function is being used the box is stuck on DELETING.
I have done all the switch offs, unplug, kick it around the room etc but no luck. It will not allow me to access 'system' or 'installation' or 'format disk' so I am stuck as well.
It would seem that the HDD is DAMAGED ?? so is the only solution to this to REPLACE the HDD ?? If I do this surely I will lose the OPERATING SYSTEM and then the box will have no function at all ??
Can anyone help me move forward with this ? Thanks WILLIE

I replaced the HDMI cable with a good quality one,I've not had a lock up or a freeze for about 12 days now.Before this I had to reboot most days.
