Macbook Pro 15' (Late 2011)

My macbook suddenly randomly shuts down or goes black screen. Upon hard reset I get the boot sound but no screen. Sometimes after a few tries I can log into my laptop but after some light use black screen again.

Anyone know what this could be?

Interesting thanks, just got it to boot again but it's out again, the startup sound was in a loop, I think it might be more than gpu
