How to unfreeze mp3 player

Hi, I have a failry new mp3/mp4 player, I've had it working fine for months, even had it playing three days ago. I went to turn it on yesterday and instead of coming up with the 'hello' screen, it went straight to a blank screen with a egg timer on it, then it doesn't move from this screen. Can you please give me suggestions as to how to fix it? There's no reset button, only a on/off switch not button. I've tried pressing either the menu of play button for a while but that doesn't change anything.
Thanks,
Heather
I have the same problem, it has froze up and tried holding down the menu and record button at the sametime, even let the battery die and no luck. Please assist. Fusion mp3/mp4 player (looks like a old generation ipod). Dawn
