White screen with no response to any input or hard reset.

Question

I recently tried using my iPhone, and shortly after using it the screen began to malfunction, it stopped responding to touch, froze entirely, then did some of the normal LCD breaking stuff (strobes of colours, etc).
it is now stuck on a pure white screen, I cannot get any form of response from it, or even restart it, the entire system has frozen up. After a quick Google I found most people with this problem have dropped their phones in water or another fluid, and checked the water sensor they mentioned, just to see if anyone had dropped it in water and not told me, it does not seem to have been triggered (or even exist on this model from what I saw).
I am worried about leaving it on overnight as it won't shut down and seems to be putting off a small amount of heat (minuscule amounts). I know Apple have a habit of using batteries that like to go out in style, so I'm hoping this doesn't use on of those batteries.
Does anyone have any ideas of what could be the cause and any possible solutions? iTunes won't pick the phone up, my PC cannot either, not even in a Linux distribution (and that has picked up many devices Windows won't).
I would rather not have to send it in to be repaired or replaced as there are files on the phone I need but cannot access thanks to this problem.

Sorry, never heard of a blue water sensor. I'd plug your phone in to mains, leave it overnight and try again tomorrow.
There are many places other than Apple that repair iPhones. Here are a few...
