Hi,
Please try out this solutions if this doesnot help then please take it to the nearest service center

1. Try charging and holding both buttons if nothing happens that means it is a hardware problem or the motherboard
2. Try resetting it by pressing and hold the Sleep/Wake button (on the top right of the unit) and the Home button (circular button on the iPhone?s face) simultaneously for at least 10 seconds, until the Apple logo appears.
3. Just try resetting it... Here's the logic: When your iPhone dies, the internal RAM shuts down after the reserve battery power is used. This in turn sleeps the motherboard, which is why it appears dead. Resetting the RAM on the motherboard will juice the very small amount of energy out of the battery to re-boot the motherboard. If resetting your iPhone doesn't work for you at first. Lay it in your cradle for approx. 10 minutes then try resetting. Although it doesn't appear so, you will actually be charging the battery, just without waking the motherboard.
4. Hold down the home button then plug the usb lead into the back of the computer at the same time. see if that helps!
