--------- since it won't connect to a PC, then you can't do a restoral. And since your home button isn't working, then you can't do a hard reboot. Your only option left is to call Apple at 1-800myiphone and get a new iphone replacement via warranty… Not everything that comes from Apple is flawless kiddo.

if its made in a factory, then it mayhave an issue with it. Facts of life

Hold the lock button and home button together for ten seconds until the apple logo appears on screen and then release. This will reset the phone but you won't lose anything off your phone it just clears the memory.
This sorts out loads and loads of problems with ios products like the iphone and the ipad. Good luck however if this does not work I would suggest you take the phone back to the store you purchased it from.

Try using a different charger. My son had the same problem. He thought the phone was defective but it was the charger which had stopped working.
