Default N7 Won't turn on or charge

So the other morning I wake up. I grab my tablet off the charger, click the lock button, and notice it was off. I figured it must have crashed overnight. I hold down the power button, and it doesn't turn on. I try again this time holding it down longer. It then turns on, but as soon as the lock screen shows up, the screen freezes and I can not do anything. I hold the power button down for an extended period of time, but it turns off and wont reboot no matter what. It wont charge (I assume), it isn't recognizable by my PC, and it won't turn on. I have no clue what happened. This happened randomly. I doubt it matters, but I'm running a CM11 based ROM (I think? Haven't changed it in a while, can't remember) and I have no clue what Kernel. I also noticed that the power button doesn't click as "nicely" (can't think of another word) as the vol. up and vol. down buttons. Could the power button be stuck? Any help or will I have to return it to my warrantor and start over? Thanks in advance.
