iphone 5 wont charge or turn on help please

my iphone 5 wont charge I tried everything to turn it back on. It was working one minute but then I went to go use it and it wouldn't turn on, 10 hours later and it STILL won't turn on. It was fully charged, but I charged it some more just in case - didn't work. Then, I plugged it into my computer while holding the home button down in order to update/restore it. It updated but never restored, and after that it STILLLLL won't turn on. I then tried holding the home and lock button down together for a few minutes in order to restart it, yet it still won't turn on. It is getting extremely frustrating at this point. I googled any other solutions to this problem, but all of the solutions I've basically already tried, and ended up never working.

Help, please?!
