Xperia Ray :: Battery Refuses To Charge When Drained To 0 Percent

I bought an Xperia Ray from Telus in mid-January this year. It was working fine until now. Today, the battery drained to 0%; it's done this before and I haven't had any prior issues with recharging. Now, when I try to charge, it won't do so. My computer won't recognize it ("USB device not recognized"), PC Companion doesn't recognize a phone, and it won't charge in any outlits in my house.

When plugged in, the phone flashes red and reboots itself constantly, making it past the start-up screen onto the main screen. It stays there for about 10 seconds loading my settings; however, I can't unlock the screen, the battery icon is red and not charging, and it goes from recognizing Telus to not recognizing a network or a SIM Card. I didn't download any updates manually recently. I tried removing the battery for a bit and then putting it back in.

I've tried removing and putting back the SIM Card. Nothing works. Randomly, the LED will be orange, and pressing the Power button shows the battery charging symbol; however, turning the phone on shows that the battery is STILL at 0% even after being on the charger for three hours. I didn't drop it, expose it to water, or do anything that may damage the phone. I'm on Windows 7 Home Premium 64x, if that means anything; also tried rebooting, but my laptop refuses to recognize the phone in any port.
