Just had a weird graphics crash, sign of a failing card?

So I was watching youtube and all of a sudden the screen turned into very fine, multicolored lines with some sections vertical and others horizontal. Audio still worked and I could tell that when I hit ctrl alt delete that the colored lines turned more blue so the display kind of responded. i did a hard reset and it was normal on start up.

I have a sapphire dual-x 280x, does this sound like early hardware failure or a weird glitch that probably won't repeat often. I had no crash errors or weird messages upon startup.
