Hi,
Stopping at "Starting up" may be a different error.
To fix,
1. Disconnect HDMI cable from Virgin Box (it runs to the TV).
2. Pull power cable out of the Virgin box.
3. Wait 10 secs and plug power cable back in.
4. Hit power button on Virgin box
5. Wait 10 minutes and plug the HDMI cable back into the VM box.
This process worked for me last week. Hope it helps, of course right now it may not make any difference!
