Question Ainol Novo 7 Crystal QuadCore Problem

I've recently been having problems with my Ainol Novo 7 Crystal QuadCore running JB 4.1.1. I've been having allot of problems with it in the past ever since I got it, random apps disappearing from the apps drawer, files and folders disappearing randomly. Now it won't boot and all it does is hang on the Ainol Novo 7 Crystal QuadCore start up screen! I've tried restoring it to factory default but I haven't been able to get into the factory restoration prompt.

Can anybody help me?
