Windows 7: Blue Screen - Graphics Card Possibly Related?

This has happened several times in the past few days. I fear my graphics card might need replacing? I've attached the error message below.

I logged in to play World of Warcraft and after a explosion of lines and abnormal colors, the screen went blank and then a blue screen showed up. Upon restarting regularly, I had repeated blue screens. I'm running in Safe Mode now. Thanks for any help, it would be greatly appreciated!
