I bought a A-320 brand new on news years day. It has worked fine up to last week. It kept wanting to reset all the time then it finally stopped working altogether?. It wont charge or be detected by my PC. It is stock standard with Firmware V1.2. The games and music is all fine on it?

Any ideas what I can do? Any button sequence or reset I can do to get it working again?
