Hi! My Arnova 7 G2 which comes preloaded with Android Gingerbread OS started to have the problem that when I power it on the usual pre boot black screen with Arnova logo on it appears and it stays that way for ever it doesn't progress to the home screen. It won't even turn off. The only way to turn it off is using the small pin button on the back which turns it off. It's a new tablet used for 2 weeks only please tell me how to fix this problem. Thanks!
