Pink stripes on startup screen, then all grey

Hi forum. This is what my MBP 17" early 2011 looks like when I try to boot it.

Never seen this before. After the progress bar has filled up, the screen goes all grey and then nothing more happens. If I leave it for a while, the fans rev up, but no other signs of life. This happens regardless of boot disk, I've tried a few. Does anyone have a tip or some kind of input?
