WHATS WRONG WITH MY IPAD?

Ok, so, I was just sitting there playing a game on my Ipad (the older one, if that makes a difference) and then all of a sudden it starts fuzzing and its like a greenish color. Its really staticy, its like one of those old tv's that have fuzzy, staticy, jagged things. I'm really scared. I cant do anything, not turn it off or anything. none of the buttons work. I tried plugging it in to the charger just to see if it would do anything. nothing. what do I do? is there a way to fix it?
