Grey screen, iPod nano 4g 8gb

I have an iPod nano fourth generation, 8gb. From what I can tell it can't retain a charge as it remains at a black screen when pressing any button. When I plug it into a computer, it flashes a grey screen for several seconds, turns black for several seconds, and cycles this until I press a certain combination of buttons.

Pressing the combination of menu and select prompts me with a reboot and another cycle of grey and black. Pressing back and select shortens the span of grey screens I get.

As for any recognition on my computer, I have gotten it to recognize it twice. After cycling reboots for a couple times, windows started to install the correct drivers for my iPod and iTunes prompted me for a restore. Which I did. Again, it cycled grey and black.

Second time was about the same, but with more frustration. Any help guys?
